Synology DSM 7.0 – How Well Does It Run?

18 juin 2021 à 01:10

How Well Does Synology DSM 7.0 Run on Different NAS Drives

It’s been a long road and we’ve waited close to 3 years since its initial reveal, but the release of the DSM 7 RC, the latest generation of Synology software and services, is here and Synology users new and old are getting ready to upgrade to significantly improved software platform. Unlike previous firmware updates that predominantly focused on improvements in stability, tweaks to security and adding features to existing services, this new Synology firmware update is genuinely massive by comparison (a tad like moving from Windows 8 to Windows 10). Of course, even though the software will be near enough the same for all Synology users, the extent to which it will perform, the applications available and how well DSM 7.0 runs on your NAS will depend a great deal on the NAS system you own and it’s hardware. One look at the download section from Synology reveals that the software is available across most NAS servers, big and small, released in the last 6 or 7 years, which is quite impressive given that even the lowly DS115j support it. So today I am selecting many of the latest and most popular NAS solutions from Synology and testing the extent to which they use DSM 7. From 1-bay dual-core ARM to Quad-Core 8-bay Ryzen, there is a huge degree of options to go through, so let’s get started.

How DSM 7.0 was Tested for Each Synology NAS

In order to make sure that each NAS was tested with a fair degree of comparison, each NAS tested below is using the same version of DSM 7.0 (Version: 7.0-41882). Additionally, each system used the exact same test files and were distributed throughout the system indexes identically. The following parameters for tests were measured:

  • The speed with which the user’s login was verified and access to the DSM 7 GUI was granted
  • How responsive the desktop GUI was and how quickly the system allows access & configuration via the control panel
  • How quick and responsive file management in file station was conducted
  • The performance and responsiveness of photo media in Synology photos
  • The indexing and playback speed of Synology Audio Station media
  • The playback and responsiveness of videos in the Synology Video Station Player (plus transcoding where supported)
  • Access and responsiveness of two live camera feeds in Synology Surveillance Station
  • Performance and Responsiveness from the NAS in DSM 7.0 when most/all of the above services and actions are conducted simultaneously

So, as you see, a fairly standard range of software and services to measure how different NAS systems from Synology handle and operate DSM 7. As tempting as it might be too to measure DSM using virtualisation or ISCSI benchmarks, the range of different capacity NAS, CPU choices and network connectivity in all these systems make any comparison between them largely incomparable. I consider the above services an acceptable benchmark for most home and prosumer users who want to take advantage of the DSM 7.0 and are curious about whether to upgrade or not. Let’s get started.

Synology DSM 7.0 on the DS120j – Should You Upgrade?

The Synology DS120j is a remarkably modest NAS system in size, capacity and internal hardware. This is precisely why it really surprised me when I saw that it too would feature a DSM 7.0 upgrade.

CPU Model Marvell Armada 3700 88F3720
CPU Quantity 1
CPU Architecture 64-bit
CPU Frequency 2-core 800 MHz
Hardware Encryption Engine YES
System Memory 512 MB DDR3L non-ECC

It performed surprisingly well and below you can find the video detailing how well it performed:

Synology DSM 7.0 on the DS220j – Should You Upgrade?

By far the most popular cost-effective entry in the Synology desktop portfolio is the DS220j 2 bay NAS box. Arriving with the popular Realtek CPU, but just 512MB of DDR4 memory, it is a fairly low powered server drive and despite the clear need for Synology to look after this popular tier of affordable solutions, even here I am surprised that it supports DSM 7.0 – but in a good way. 

CPU Model Realtek RTD1296
CPU Quantity 1
CPU Architecture 64-bit
CPU Frequency 4-core 1.4 GHz
Hardware Encryption Engine YES
System Memory 512 MB DDR4 non-ECC

Indeed, Synology themselves do highlight that DSM 7.0 operates at its best when using at least 1GB of memory to ensure that all of the system services operate to the best of their ability, which is double that of the default memory in the DS220j. Nevertheless, despite a few limitations in Synology Photos and the system slowing down a pinch when simultaneously using surveillance cameras, it performed surprisingly well and you can find out more below in the video.

Synology DSM 7.0 on the DS220+ – Should You Upgrade?

For many users, the Synology DS220+ is the entrance point for those who are looking at multimedia use or who were looking to migrate away from Cloud services like Google Drive, Google Photos and Dropbox, in favour of their own private cloud that is still rather capable. The DS220+ is also the most affordable solution in the brand’s current modern releases to feature an Intel Celeron processor and DSM 7.0 is definitely able to take advantage of this.

CPU Model Intel Celeron J4025
CPU Quantity 1
CPU Architecture 64-bit
CPU Frequency 2-core 2.0 (base) / 2.9 (burst) GHz
Hardware Encryption Engine (AES-NI) YES
System Memory 2 GB DDR4 non-ECC
Total Memory Slots 1
Maximum Memory Capacity 6 GB (2 GB + 4 GB)

Although there are numerous individual apps and services built into Synology DSM 7 that are available on pretty much any NAS, there are several more SMB (Small-Medium Business) products on the platform that require an x86 64-bit processor minimum. Services and features such as Virtualisation and more enterprise level backups from Active Backup Suite immediately become available at this tier of Synology NAS hardware. Unsurprisingly, DSM 7 ran well on the DS220+, multitasking beautifully even with the default 2GB memory. Likewise, the Synology Photos application performed very well, even when it was live recording from two IP cameras in surveillance, transcoding a 1080p video file, playing back an audio file and duplicating 50GB of data – all at the same time. For more information on how the DS220+ performed with DSM 7, watch the video below.

Synology DSM 7.0 on the DS920+ – Should You Upgrade?

The Synology DS920+ 4 bay NAS system is BY FAR the most popular desktop NAS in the brand’s portfolio. This NAS is also considered the last genuinely prosumer grade solution in the portfolio, before things get a little bit more business and enterprise at the higher tiers. The system hardware on offer in the DS920+ give you access to the entire range of Synology software and services available in DSM 7.0 that you find in all other NAS systems in this article so far, but also so provides additional information, settings and functionality in the storage manager. 

CPU Model Intel Celeron J4125
CPU Quantity 1
CPU Architecture 64-bit
CPU Frequency 4-core 2.0 (base) / 2.7 (burst) GHz
Hardware Encryption Engine (AES-NI) YES
System Memory 4 GB DDR4 non-ECC
Total Memory Slots 1
Maximum Memory Capacity 8 GB (4 GB + 4 GB)

DSM 7 alongside general improvements in access time and responsiveness of the system compared with DSM 6.2, also makes vast improvements in caching in a number of ways. From the general intelligent memory utilisation of the system and in the case of the DS920+, its 4GB of memory and how DSM 7.0 takes advantage of the NVMe slots. DSM 7 should run perfectly on a Synology DS920+ and in our comparison testing, this was well established with the system performing all tasks incredibly quickly and simultaneously with little to no aggressive increase in hardware resource consumption. As before, I recommend you check out the video below for more information on just how the DS920+ performed with DSM 7.0:

Synology DSM 7.0 on the DS1621+ & DS1821+ – Should You Upgrade?

Synology introduced the AMD embedded Ryzen processor to their range of SMB solutions in late 2020 and despite the development cycle of DSM 7.0 taking several years prior to this, it is completely supported on these newer gen CPU devices. The V1500B processor is found on the DS1621+ and DS1821+, among many others in the last year or so and given the business class services and and office collaboration tools included in DSM 7.0, its performance on these new small-medium business class servers is remarkably important for Synology’s continued growth into pre-existing SaaS integrated environments (whether to replace or exist in parallel as bare-metal)

CPU Model AMD Ryzen V1500B
CPU Quantity 1
CPU Architecture 64-bit
CPU Frequency 4-core 2.2 GHz
Hardware Encryption Engine (AES-NI) YES
System Memory 4 GB DDR4 ECC SODIMM
Memory Module Pre-installed 4 GB (4 GB x 1)
Total Memory Slots 2
Maximum Memory Capacity 32 GB (16 GB x 2)

Although only the 6 bay NAS was tested in the video below, it shares a near identical hardware architecture to the 8-bay desktop alternative and several rackmount Ryzen powered rackstation solutions. This was the best example of DSM 7 that I tested in the videos and it was easily the least resource impacted NAS of all. Although CPU utilisation spiked briefly during video playback, this was largely due to the non-embedded graphics CPU of this system than anything to do with a DSM7. Below is the video of how how this NAS handled DSM 7.

QNAP QMiroPlus-201W & QMiro-201W Mesh Router & NAS Review

16 juin 2021 à 16:00

QNAP QMiroPlus-201W & QMiro-201W Mesh Router+NAS System Review

Of all the devices that I talked about here and on YouTube, there is one device that I would wager is inside 99% of people’s homes these days, namely a router. For most users, the router provided by their internet service provider is more than proficient for the day-to-day handling of network and internet traffic in their home. After that, you enter the realm of prosumers, businesses and enterprise whereupon the typical low-level ISP router just will not cut it. It is at this point when premium and fully-featured routers enter the market and it is with this audience that we find QNAP launching their latest mesh router and combined NAS system. I say latest, as this is in fact the second router that QNAP has ever launched (the first being the QHora-301W – Review HERE) and the QMiroPlus-201W and QMiro-201W router systems are an impressive entry into this slowly growing product family. With the primary hub unit arriving with Intel-powered NAS architecture alongside RAID storage options and expandability, combined with the mesh connection and business class router software available in the QMiro-201W satellite pods, this is clearly something a little different to the mesh routers discussed throughout 2020/2021. QNAP has a long-established reputation in the NAS market and has expanded it noticeably with a significant range of network switches now in their portfolio. Are this new mesh router and NAS combination system a smart move by the brand or are they stretching themselves too far? Does the QNAP QMiroPlus-201W and QMiro-201W mesh system deserve your data?

QNAP QMiro-201W Mesh Router+NAS Quick Conclusion

QNAP has presented a fantastically unique router here and included hardware features that are genuinely unavailable from any other brand in the world like this right now in a single package. As mesh router systems go, it does seem a little pricey and given its lack of Wi-Fi 6 as available in the Qhora-301W, this may struggle with beating other solutions that support 802.11ax to the checkout. However, the QNAP QMiroPlus-201W and QMiro-201W mesh router system is at its best when it is purchased and deployed as a combined NAS storage system and intelligent mesh router. Indeed, an Intel quad-core 4GB memory 2-Bay NAS system will already set you back around $300-400 on its own and looking at this system in terms of purchasing it as an alternative to a NAS and router separately does makes that price tag a little bit more palatable. The QNAP QMiro-201W satellite modules on their own are perhaps a little underwhelming, but utilising them in conjunction with a QMiroPlus-201W unit, with its advantages in QTS for backups, multimedia, Plex media server, containers, surveillance and more 4K media and you’ll find that QNAP has really built something fantastically unique here. I just wish it had Wi-Fi 6…


  • Router & NAS solution in one
  • Slick Router GUI with easy access
  • Mesh Support with Easy Connect
  • NAS has 2.5Gbe
  • FAST setup and inc wall brackets
  • Satellites are fanless/noiseless and ‘Plus’ is quiet
  • USB 3.2 Gen 1 Ports on Plus and Nodes
  • Works straight out of the box
  • Free SD-WAN software and services included
  • QTS on the PLUS is a FULL version and Intel Powered
  • Design and colour will split opinion
  • 2 Year Warranty is shorter than 53D with similar hardware
  • Nodes (non-Plus) are pretty underwhelming as standalone routers without PLUS hub

QNAP QMiro Mesh Router+NAS – Packaging

Understandably, QNAP has put a little bit more presentation into the retail packaging of the QMiroPlus-201W and QMiro-201W, given that this system is more likely to be sold on the shelf of your local I.T shop than many of their primary NAS solutions. Arriving with plenty of brand livery, product images and descriptions, this is all fairly standard and tells you plenty about the product’s hardware and software capabilities.

Removing the outer packaging, we find that QNAP has packed the QMiroPlus-201W and QMiro-201W in exactly the same way that most routers are packed (thin card moulded frame box) which bears stark contrast against how their NAS drives are packaged. Is this some kind of industry-standard or just the most effective way to package items like these? Who knows.

The included accessories for the QMiroPlus-201W and QMiro-201W are similar but with certain distinctions that are relevant to the scale of each device. The QMiroPlus-201W unit arrives with a cat5e 1M cable, screws for 2.5″ SATA drive installation, information on first-time setup incl, information on the inclusive 2-year warranty and an external PSU rated at 60W.

The QMiro-201W has near enough identical accessories, though understandably this unit does not feature the ability to install storage media aside from USB, the QMiro-201W simply has as the manuals, Ethernet cable and more modest external PSU at 24W.

As mentioned earlier, the QNAP QMiroPlus-201W allows you to install two hard drives or SSD inside the main chassis. This storage media needs to be purchased separately and QNAP has no plans to include the storage media in the system by default, which I think most users will be pleased with as it allows a certain degree a flexibility in its deployment. Additionally, as the QMiro-201W lacks the SATA storage bays, it is noticeably smaller in size. Let’s take a look at the design of the QNAP QMiro-201W and QMiroPlus-201W mesh router NAS combo systems.

QNAP QMiro Mesh Router+NAS – Design

Taking a closer look at the design and casing of each QNAP mesh router, you can see that it bears more than a striking resemblance to a number of their systems. Featuring a huge degree of ventilation to help maintain system temperature throughout the fanless QMiro-201W modules and fan-assisted QMiroPlus-201W hub, each unit is quite boxy in design and arrives at roughly the same height and width as a traditional hard drive. Though noticeably deeper. I’m still not a huge fan of the light blue colour scheme, but I know I am very much in the minority.

Taking a look at the QMiro-201W first. In all likelihood, this is the unit that will be most visible throughout your home or business if you deploy this system. There are no external antennas and the system is fanless. With a lot of mesh router providers creating much rounder and smaller mesh node points, QNAP has opted for a tall and narrow chassis design, likely because unlike a lot of other mesh node points, this has a noticeably larger degree of local connectivity over LAN and USB available.

The main QMiroPlus-201W unit however is significantly more capable and arrives in a larger chassis. This central unit features the same internal network processor and memory, but also features the parallel NAS storage system with its own dedicated CPU, memory and storage bays. Although the general design and shape on each unit are similar, the pub unit is around 3x larger in-depth and also features active calling internally.

The internal active cooling is assisted throughout the entire system by plenty of passive cooling throughout the entire external casing, with vents on almost every side. Indeed, the removable front panel only serves to cover the internal storage media days and does not cover any ventilation even when applied.

The QNAP QMiro-201W unit on the other hand relies exclusively on passive cooling due to its fanless design, with even more vents and physically large heatsinks internally. As mentioned, the individual QMiro-201W units may seem a tad larger than average mesh router points but there is a lot contained within each unit and needs appropriate heatsink coverage to maintain optimal efficiency one would assume.

The difference in scale between the QMiroPlus-201W and QMiro-201W is actually quite noticeable and the larger QMiroPlus-201W unit is as big as a regular NAS system.

Removing that front panel shows us the twin removable SATA storage bays. One main difference between this and most typical 2-Bay NAS’ is that this system utilizes more compact 2.5″ in storage media, which although more power-efficient and makes less noise, means that it does limit the available storage capacity that this system will be able to support at maximum. That said, this system does support 15mm height drives and therefore means it will support noticeably larger small form factor drives, as well as bulkier SATA SSD which marginally makes up for the total reduced capacity. 

Inside these two storage bays, we find combined SATA power connectors and no unnecessary loose wires for installation. Indeed when installing the storage media inside, the system allows utilisation of individual drives or combined drives in a RAID 0/1 set. The storage media in these bays is primarily used by the parallel QTS NAS software for hundreds of different modern NAS purposes, as well as supporting snapshots and multiple types of backup operation between this, the router and other storage platforms like cloud, USB, cloned directory, other NAS and other client devices.

Although the use of 2.5 in SATA drives is a little underwhelming, it kind of makes sense in the stature of this device and the low-level discreet build of your average router. Also, 15mm height 2.5″ drives are pretty affordable these days and available from numerous brands. Personally, I would probably install a couple of SATA SSD in this system as then you can really take better advantage of the NAS architecture internally.

QNAP QMiro Mesh Router+NAS – Connections

Taking a look at the rear of the QNAP QMiroPlus-201W and QMiro-201W, not only can we see plenty of ventilation but we can also see far more familiar connectivity as is found on typical QNAP systems. Even the relatively understated mesh satellite node QMiro-201W unit is a little bit more upscaled in design on the rear than a lot of other mesh router extras. Once again, I am still not a tremendous fan of the colour scheme, but I do like tonnes of passive ventilation and the good balance of functional yet compact design. It might be a little boxy for some, but I like it.

Taking a closer look at the QNAP QMiro-201W module on its own we find and that it arrives with multiple gigabit connections and the option to make local USB storage network accessible. Indeed, I like the fact that this system features twin RJ45 ethernet ports, one for WAN and another for LAN (though both can be used for typical LAN if preferred), it allows a decent depth of coverage across the three-band frequencies over Wi-Fi and these two local wired connections. Of course, giving this is Wi-Fi 5 in architecture and that this is going to be a mesh node point, it is pretty unlikely that this system could fully saturate both 100 Megabyte wire connections, but nevertheless, with the right port priority settings and the right mesh node layout in the environment, these would still prove very useful.

The system also arrives with USB 3.2 Gen 1 connectivity at 5Gb, which allows you to attach an external drive to be accessed via the QNAP QMiro-201W network. However, it is worth highlighting that when utilising just the QMiro-201W router, access to this drive is a great deal more limited than in the NAS software and hardware equipped QMiroPlus-201W system. Utilizing just QuRouter on the QNAP QMiro-201W will result in only having low-level breadcrumb style browser access to the USB drive and definitely not anything approaching the slick layout of File Station.

Switching over to the QNAP QMiroPlus-201W and things are noticeably ramped up in terms of port and connections. The system features a great combination of NAS and router style connectivity, from significantly more ethernet ports to local storage connectivity improvements. There is the active cooling fan, of course, something that is absent from the QMiro-201W unit, but this does not make much noise when in operation thanks to the system using rather modest style hard drives. The fans certainly ramped up when system was first initialising, but this soon passed.

Additionally, the main QMiroPlus-201W system arrives with two USB ports that are once again 5Gb in architecture, but this time the drives you attached can be utilised in creating a wider backup strategy, for use in virtual machines and containers on the NAS router, can be used for external storage and additional ethernet adaptors up to 2.5GbE and 5GbE. Lastly, QNAP also provides a range of USB expansion devices that allow you to add additional bays of storage to Venus and expand the storage pools and raid options available to you. Once again this is a significant jump over the available additional storage options available on most router systems and even a lot of 2 bay NAS systems in the market.

In terms of network connectivity, the QNAP QMiroPlus-201W has 5 available Ethernet ports. These can be broken down into 1 port for the NAS and 4 ports for the router, however, the router ports still allow complete access to the NAS GUI and system in general. The internet ports are all gigabit ethernet in architecture which is fairly predictable, however, the single dedicated NAS ethernet port is a 2.5GbE port, allowing connectivity of up to a potential 270MB/s per second. It is worth highlighting that both the NAS and router run parallel and both systems can be powered down or restarted for updates etc without it automatically affecting the other, something that will be hugely useful and relieve potential frustration in busier moments. 

The active cooling fan mentioned earlier can have its RPM adjusted on the fly quite easily but it is recommended to leave the system running at automatic to ensure the system maintains perfect internal working temperatures. Also, we have to be realistic here and know that this is both a router and a NAS system, the latter of which can generate an impressive amount of heat whilst on for days, weeks and months at a time. This is made infinitely more important when you consider the system utilizes an Intel Celeron processor, which works at its best when the system has a clear and well-ventilated working environment.

That’s about it for the external connectivity on this rather innovative device and now I want to take a little look at the insides, the antenna and see how well organised the QNAP QMiroPlus-201W is internally.

QNAP QMiro 201W Mesh Router+NAS – Internal Hardware

Unsurprisingly, once we removed the external chassis of this rather compact NAS router combo, we find that the internals are packed together quite neatly in order to maximize available space. There are numerous smaller heatsinks around the system that cover the important dual CPU design and the storage media area, just above this large baseline heatsink for the controller board.

A closer look at the top of the device reveals the four antennas that provide full coverage across this system when in operation, not external antenna that allows a more customisable area of coverage control, which may disappoint some users. Alongside this, there is a slight concern about the heat and efficiency of a system like this in such a compact chassis with the antennas so close by. However, this is largely ignorable as even early testing of this system both in and outside of mesh setups proved very stable and in our software review, we were able to test this further with file uploads to the NAS. The lack of Wi-Fi 6 is still a bitter pill to swallow though.

The large silver heat sink that occupies the majority of the base of the system is where the bulk of the performance components are located. Considering the scale of the unit, it seems rather aggressive but given that you have the active cooling fan drawing are over this and the twin SATA storage bays, the more cooling, the better!

Both the QMiroPlus-201W and QMiro-201W use the same Qualcomm quad-core processor for handling the router operations, which also features 512MB of DDR3 memory too. As meagre as this might sound, this is pretty impressive for just handling the router side of things and along with the support of multiple SSIDs, different LANs supported and configuration options available in the QuRouter software for MAC Address/client device handling/IP tracking, that means this system can handle a decent number of simultaneously connected clients with ease and your network environment can be adjusted on the fly quite well.

The network-attached storage side of the QMiroPlus-201W on the other hand uses that Intel J4125 processor that hugely popular at the moment in a number of SMB NAS systems, with integrated graphics for 4K and 1080p video, handling of virtual machines and containers, supporting several surveillance applications and of course all of the multifaceted means with which to create a multi-tier backup strategy, there is a lot that this system can do and that this CPU supports in QTS. This CPU is further improved with the inclusion of 4GB of DDR4 memory to keep things running across multiple users and multiple services at once. Though it is worth highlighting that despite the fact that this CPU support up to 8GB of memory, the system cannot be upgraded from the standard 4GB in the baseline model. Not a huge deal breaker, but those of you that will expand the business utilities found in the NAS software may find 4GB a limiting long-term.

Overall, the internal hardware of both the QMiroPlus-201W and QMiro-201W is fairly impressive, though clearly the QMiroPlus-201W has the lion’s share of innovative internal tech. Arguably the QMiro-201W units are much less impressive when seen as stand-alone units, but the integrated hardware of the QMiroPlus-201W and then its scalability used in conjunction with one or more QMiro-201W units changes thing is dramatically for the better. However, good hardware is nothing without decent software and the new QNAP mesh router and NAS system are technically two parallel operating systems in one. So let’s take a look at both QTS and QuRouter.

QNAP QMiro 201W Mesh Router+NAS – Software

The QuRouter software that is included on both the QMiroPlus-201W and QMiro-201W is functional if arguably fairly standard router control deck. There are a few features such as easy remote access, VPN integration, profile control and file management with the connected USB drive that are quite unique to the system and presented very well. But the rest of the features presented here are all quite standard for a paid router compared with that of your bog-standard ISP router. I have touched on the software side of things on the QNAP QMiroPlus-201W a little already, but to go into them in more detail, you need to look at them from two different end-user perspectives, home and business (enterprise really). Tools for both and the services are available to both, but each certainly has appeals to its own audience. The QMiroPlus-201W’s primary interface for most small-mid level users will be the new QuRouter software it arrives with. I will certainly go into more detail on the software review coming soon on the QMiro on Youtube, but even in this short stint of time using it, I am impressed by the GUI. Compared with the Netgear router management (looking remarkably 2000s even now in 2020) and my Virgin ISP router (fantastically limited UI), the QuRouter software is very clear, arriving with guides, tips and pointers – each allowing the user to create a very unique and secure setup that fits their needs. This software controls and manages all 4 of the LAN/WAN ports, allowing you to create quality of service protocols, priority assignment to ports and devices, as well as create virtual NETWORKS (vLANs) inside your main network, so you can group devices appropriately to their status in your home/business. Though the biggest question for many users looking at this system is not the LAN connectivity, but the choice to NOT include WiFi 6.

WiFi 5 vs WiFi 6

The QMiro is advertised as a AC2200 router which (as already touched on) means that you have blanket wireless coverage of a shared 220MB/s. This does not include the 400MB/s wired coverage via the 4x 1Gb LAN potential, but it is worth noting that no single band 5Ghz A/C/N connected client over wireless can get higher than 768Mb/s (76MB/s). The benefits of WiFi 6 in terms of data packet handling, both in rapidity and simultaneously are quite well noted, though the distance is not quite as broad as the older wireless protocol. Additionally, that wireless coverage in the QNAP Qhora-301W released last year is spread across multiple bands, with the system supported 3x 2.4Ghz and 3x 5Ghz bands, over MU-MIMO. It is still a tremendous achievement and still comfortably meets the WiFi 6 standard. So if QNAP could include it in the QHora, then why not the QMiro? Who knows. Another handy advantage of the QMiroPlus-201W is the ability to create 3 separate SSIDs (wireless networks) each with its own wireless connection name and security login credentials. The separate wireless networks use separate frequency/bands with 1 on the 2.4GHz band and 2 on the 5GHz band. Most routers include the ability to create a ‘guest’ SSID on the single lower 2.4GHz band, but on the QMiroPlus-201W, you can create fully featured wireless networks and give them appropriate security privileges and access to the selected wired networks and vLANs you create via QuRouter.


Under the traditional enterprise network architecture, multi-site connections must be connected back to the head office, which often suffers from insufficient bandwidth. In addition, the price of VPN equipment on the market is expensive, which is far from the load of ordinary SMEs. With QNAP SD-WAN technology (QuWAN), multi-point units can flexibly form a network at any point, realizing a low-cost and highly flexible network deployment architecture.

QuWAN Orchestrator provides a convenient and powerful cloud network centralized deployment and management platform. IT personnel can remotely deploy all local network equipment at each branch in the headquarters, without having to travel to various locations The network deployment of ZTP truly achieves zero-touch deployment (ZTP, Zero Touch Provisioning), and can perform multiple functions such as bandwidth monitoring, parameter setting, and traffic analysis on a single platform. Endpoint devices can directly connect to QMiroPlus-201W via wireless or wired LAN, and easily join the SD-WAN network. This is achieved with the three first-party tools:

QuWAN Orchestrator

Log in to , you can view the connection status of all devices that have joined the network, and apply network settings to all devices in batches. You can also set up real-time notifications for real-time remote troubleshooting and control connection problems

QuWAN Agent

You need to enable QuWAN Agent on the QNAP device and add your device to the Mesh VPN networking environment (that is, join QuWAN Orchestrator).

QVPN Client

After installing QVPN Client on mobile phones and computers, and connecting with QHora-301W, you can access multipoint intranet resources.

In addition to being built in QMiro and QHora routers, QuWAN is actually FREE and can also run on compatible devices such as QNAP NAS, QGD switches and QuCPE series servers. It also works with exclusive QVPN Client software to enable teleworkers/WFHers to pass Terminal devices such as computers, laptops, and mobile phones are connected to SSL VPN, which facilitates the formation of a micro-segmentation network architecture that is separated by different departments as large as a state or country, as small as a single site, and through the central cloud Unified management of the platform. QuWAN is now available for free in QNAP App Center, and the license fee is free of charge.

And the rest:

  • Dynamic Frequency Selection (DFS) channels (Auto, custom)
  • RTS/CTS (Request to Send/Clear to Send) function
  • Guest wireless options
  • Wireless scheduler
  • Protocol-based firewall (TCP, UDP, ICMP, TCP+UDP)
  • Firewall rules based on domain names and IP addresses
  • Port forwarding and Network Address Translation (NAT)
  • Support FTP ALG, PPTP ALG and SIP ALG
  • Secure remote access with L2TP, OpenVPN and QBelt (QNAP proprietary) protocol
  • VPN client management
  • USB Settings: FTP Server, Device User, USB usage condition

So, the QMiroPlus-201W really is a fully-featured router for home and business. This review is primarily centred on the hardware of course, but the software review below should give you a better understanding of what the QMiroPlus-201W and QMiro-201W can do in both router services and NAS:

The QTS NAS software included on the QMiroPlus-201W, on the other hand, is a great deal more unique and despite its rather modest stature and the fact that it shares billing with the router OS, this is not a pared-down version of the fully-featured NAS Software. The QMiroPlus-201W arrives with QTS 4.5 and access to all of the software and services that you would have in a prosumer class system. There are a few small differences such as the use of QVR elite and not QVR Pro for reasons of hardware efficiency, but all in all, this is a complete system server and cloud management user interface. For those unfamiliar with the QNAP operating system, it arrives with hundreds of free applications, can be accessed from a web browser or desktop client, arrives with many, many apps for mobile on IOS and Android and is definitely in the top two operating systems you can get for network-attached storage devices. Often compared with their biggest rival Synology NAS and DSM, QNAP QTS GUI is designed in a way that will definitely appeal more to Android and Windows users, giving you everything you will need from a network-attached storage device in 2021 and arrives with constant updates for added features and security.

QNAP File Management Highlights

  • File Station – File Browsing and Management Tool
  • QSirch -Intelligent and Fast System-wide search tool
  • QFiling – Smart and customizable long term storage and archive tool
  • SSD Caching Monitor and Advisor – Allowing you to scale your SSD cache as needed, or get recommendations on how much you need
  • Microsoft Active Directory– Support and cross-platform control of Active Directory processes
  • Access-Anywhere with myQNAPcloud – Safe and secure remote access over the internet to your storage systems, apps or just file storage
  • Qsync for multiple hardware environment backups and Sync – Client applications that can be installed on multiple 3rdparty devices and create a completely customizable and scaled back up network between your devices

Then you have KEY applications that are used on the QNAP NAS system that moves into tailored data access and use, such as:

  • Hybrid Backup Sync 3 – Allows you to Backup and Sync with Amazon Glacier, Amazon S3, Azure Storage, Google Cloud Storage, HKT Object Storage, OpenStack Swift, WebDAV, Alibaba Cloud, Amazon Drive, Amazon S3, BackBlaze B2, Box, Dropbox, OneDrive, Google Drive, HiDrive, hubiC, OneDrive, OneDrive For Business, ShareFile and Yandex Disk. As well as backup to another NAS over real-time remote replication (RTRR) and USB connected media. All scheduled and all accessible via a single app user interface.
  • vJBOD and Hybrid Mount – Gives you the ability to mount cloud storage as a visible drive within the NAS (and the apps access it as if it was local) or mount a % of space from your NAS onto another as a virtual chunk of space to use
  • Multimedia Console – one portal access point to manage media access, searching, indexing and transcoding on your NAS device.
  • Photo, Video and Music Station – Multiple file type tailored applications to access data in the best possible way that is suited to their output – along with smart searching, playlists and sharing
  • Virtualization Station – Used to create virtual computers that can be accessed anywhere over the network/internet with the correct credentials. Supporting Windows, Linux, Android and more. You can import an existing VM image to the NAS, or you can even download Linux and Windows VMs directly to the NAS for trials for free
  • Container Station – much like the VM app, Container station lets you mount and access smaller virtual tools and GUIs, then access them over the network or internet.
  • Linux Station – Handy application to deploy multiple Linux based Ubuntu VMs from the NAS, all easily and within a few clicks
  • QVR Elite and Surveillance Station – Surveillance applications that allow you to connect multiple IP cameras and IP speaks to your network and manage them with the applications. Arriving with 4 camera licenses for Surveillance Station and 2 licenses for QVR Pro (the better one IMO), QNAP is constantly updating this enterprise-level surveillance application – adding newer security hardware and software tools for 2020 (see QVR Face and QVR Door)
  • QuMagie – Facial and Thing recognition application to help you retrieve, tag and catalogue photos by its use of AI to actually ‘view’ all your years of photos and let you search by the contents of them, not the file names.
  • Download Station – A download management tool that can handle HTTP, BT, FTP and NZB files in bulk to be downloaded to your NAS drive and keep safe. As well as keeping an eye on your RSS feeds and keeping your podcast downloads automatically updated with every episode
  • Malware Removers and Security Councillor – Along with Anti Virus software trials on the app centre, QNAP also provide numerous anti-intrusion tools and even a whole app interface to monitor in/outgoing transmissions with your NAS. It can make recommendations to beef up your security and keep you safe

You cannot really fault the level of software and service available in this single package solution. The fact that you only have access to QNAP QTS software platforms on the QMiroPlus-201W and not the QMiro-201W is disappointing but understandable. And the QuRouter software, despite still falling behind in a few key areas compared with Synology Router Manager, is still an excellent and functional router management software platform.

QNAP QMiro 201W Mesh Router+NAS – Conclusion

It is genuinely hard to dislike or write-off the QNAP QMiroPlus-201W system, giving it wide-ranging software abilities and impressive hardware available on both the router and NAS side. The capability, design and features of the QMiroPlus-201W do somewhat overshadow the QMiro-201W module, clearly leading to this system only really reaching its potential when purchased as a multi-node kit, but it is still a capable and functional system independently. The QuRouter software, although clear, user-friendly and functional, has perhaps not evolved as much as I would like in the six months since I first saw it, but QTS for NAS runs on this system beautifully and delivers everything I expected. Much like the QNAP guardian series that combined NAS and switches to relative success, the QMiro’s attempt to merge a separate private server and router purchase into one is still yet unproven in the eyes of the public, so its effectiveness will likely vary from user to user. Clearly, the lack of Wi-Fi 6 on this system is going to be a deal-breaker for many and the choice of media drives and inability to upgrade memory is definitely an area that QNAP dropped of the ball on here but nevertheless, I do recommend the QNAP QMiroPlus-201W and QMiro-201W as certainly your next NAS and as a viable alternative to separate hardware in your home or office.


  • Router & NAS solution in one
  • Slick Router GUI with easy access
  • Mesh Support with Easy Connect
  • NAS has 2.5Gbe
  • FAST setup and inc wall brackets
  • Satellites are fanless/noiseless and ‘Plus’ is quiet
  • USB 3.2 Gen 1 Ports on Plus and Nodes
  • Works straight out of the box
  • Free SD-WAN software and services included
  • QTS on the PLUS is a FULL version and Intel Powered
  • Design and colour will split opinion
  • 2 Year Warranty is shorter than 53D with similar hardware
  • Nodes (non-Plus) are pretty underwhelming as standalone routers without PLUS hub

Synology Upgrade Cards Guide – 10G, NVMe, 25Gbe and More

14 juin 2021 à 16:00

A Guide to Synology PCIe Upgrade Cards

There comes a point in the lifespan of most Synology NAS drives, big or small, that the performance, bandwidth and general throughput that the device is capable of hit a bit of a glass ceiling. Perhaps it is those rather restrictive 1Gbe ports in 2021, hardware features like M.2 slots of more modern systems that are sadly missing from your own older release or simply that your own external network hardware environment has scaled up noticeable and your Synology NAS is now a bottleneck? Sometimes replacing the NAS with a newer model is the only answer, but sometimes the operational lifespan of your NAS can be noticeably extended by installing a PCIe Upgrade card. Synology NAS for Prosumer/SMB users and above (typically 5-Bay upwards) have included PCIe upgrade slots for many generations previously and the range of Synology Add on cards available have grown to meet demand. So today I want to go through the current range of cards, which what each type can do, what it cannot do and help you choose the right PCIe Upgrade Card for your Synology NAS Server.

Important – An upgrade card in your Synology NAS does not AUTOMATICALLY mean you will achieve the maximum reported speed/performance (i.e installing a 10Gbe PCIe Upgrade Card does not immediately make your data externally accessible at 1,000MB/s. Upgrades, ranging from network interface improvements to internal SSD performance cards, will only provide you with the BANDWIDTH the achieve that speed, you will still need high-performance media and/or multiple media drives in a RAID to fulfil this bandwidth. So, in water simple terms, the majority of cards will increase the WIDTH or the pipe, but you still need to make sure you provide enough water and pressure to go through it!

Additionally, sometimes you are best served to increase the memory on your Synology NAS in order to get better performance on key applications and services. Use my Synology NAS Memory Upgrade Guide to help choose the right Synology or Unofficial Memory for your needs.

Synology Copper 10Gbe Upgrade Cards

Likely the first Synology Upgrade card that you looked at and certainly one that is favoured by users who are scaling up from a small home/business/shop solution and into something with noticeably higher bandwidth, 10Gbe network cards are becoming increasingly affordable. There are two main versions of 10G on the market, fiber optic-based (know as SFP+ and we will touch on that later) and copper-based (typically known in tech as 10GBASE-T). Most users who are scaling up from 1Gbe for the first time will opt for copper-based 10Gbe on their Synology NAS, as it uses near-identical cables to the typical RJ45 found in all their other kit (the only small difference being that in order to use 10Gbe at longer distances, you should use a Cat 6 cable, whereas most 1Gbe devices arrive with Cat 5/5e – looks IDENTICAL and will still work regardless, it’s just a latency thing). Synology has released several versions of 10Gbe copper cards over the years, refreshing the range every few years to ensure the best controllers are used and supported by the newer NAS systems. Synology has two different dedicated 10GBASE-T PCIe upgrade cards in the E10G18-T1 and E10G18-T2, which are 1 port and 2 port respectively. Both are PCIe Gen 3 x4 and x8 respectively (but will still work on PCIe Gen 2 x2 slots and above without a bottleneck (pre-2017 series devices). Additionally, like all the cards in the Synology PCIe Upgrade Guide today, drivers for these cards are already included in the Synology DSM software.

Currently Available 10GBASE-T 10Gbe Cards

E10G18-T1 1-PORT CARD – $163 E10G18-T2 2-PORT CARD – $309

Pros & Cons of Synology 10Gbe Upgrade Cards

  • Supported on pretty much ALL Synology NAS with a PCIe Slot since 2010/2011 series
  • Auto-Negotiation Enabled (so will scale to 1G-2.5G-5G in line with clients
  • Dedicated onboard Aquantia Controller
  • 5 Year Warranty is first class at this level
  • Quite Expensive for 1/2 Port 10G Card in 2021/2022

Synology 25Gbe E25G21-F2 Upgrade Card

A relatively new add on for the Synology PCIe Upgrade range (thanks to their embracing of SAN protocols in a bigger way in DSM 7.0, even renaming iSCSI manager to SAN Manager), the new E25G21-F2 card is a fibre optic-based 25 Gigabit Ethernet, 2-Port (so potential 50Gbe) card that is designed specifically for Synology NAS systems. Clearly (and as mentioned in my introduction) this card opens the pipeline for 2500/5000MB/s speeds, but you will need some SERIOUS storage media configurations in your NAS in order to saturate it! Supporting a range of ethernet connectivity and transceiver types (including Optical SR, LR and DAC hardware), this card is clearly designed with massive 12-Bay+ Xeon equipped and large distance setups in mind. The Synology E25G21-F2 card also supports auto-negotiation (i.e backwards compatible and will automatically switch to) 10Gbe SFP+, so for those who are considering upgrading their rackmount to 10Gbe over fibre and have a decent budget to play with, might benefit to spend a little more on this 25Gbe alternative, as there is only around $120-150 between them). Unlike other PCIe cards in this list, the compatibility of the E25G21-F2 25G card is a little thinner, largely down to the forced need to have a PCIe Gen 3 x8 slot (potentially 8000MB/s card-to-board bandwidth), which only really appeared on Synology systems since 2016/2017 onwards. Additionally, you are going to need at least 12-14 Enterprise-grade (Pro/Data Center) Hard Drives or 8+ Pro class SSDs in order to make the most of this card on your fiber network. A very impressive card, but as upgrades go, arrives with a number of high price system/media caveats too.

Currently Available SFP28 E25G21-F2 Card

E25G21-F2 2-PORT 25Gbe CARD $369

Pros & Cons of Synology 10Gbe Upgrade Cards

  • 25Gbe and potential LAG/Trunk 50Gbe is just awesome
  • 5-year Warranty and Still Supported by older systems as far back as 2017 Series
  • Can be used as a 10Gbe x2 Port card and then scaled up as your network hardware environment grows
  • Although Supported by some SMB systems (e.g. DS1821+), they will NEVER reach the full performance this can offers
  • 25GBASE-T Copper – Never say never!
  • FS series:FS6400, FS3600, FS3400, FS3017, FS2017, FS1018

  • 17 series:RS18017xs+, RS4017xs+, RS3617xs+, RS3617RPxs, DS3617xs

Synology Fiber 10Gbe Upgrade Cards

Much like the previous card, the range of fibre 10Gbe cards that Synology offer are ONLY available in 2-Port builds in 2021/2022. You can use some 3rd party 1-Port SFP+ cards, but in recent years Synology has become very strict on upgrades on their systems being 1st party (highlighting that it’s difficult to support NAS users who run ‘unsupported’ configurations – make of that what you will). The two available 10Gbe cards are the 2017 series E10G17-F2 and 2021 series E10G21-F2. Both cards are PCIe Gen 3 x8, support low and full height profile installation, and both have 5 years warranty – however, the 2017 series card is around £50-60 cheaper. This is because the newer card uses a better heatsink, and seemingly supports more offload protocol/setups. In most cases, however, either card (as long as it is on the compatibility lists below) will be sufficient for a potential 2,000MB/s external throughput.

Currently Available SFP+ 10Gbe Cards

E10G17-F2 2-PORT CARD – OLD GEN – $230 E10G21-F2 2-PORT CARD – NEW GEN – $269

Pros & Cons of Synology 10Gbe Upgrade Cards

  • 10G SFP+ Still has a lot of flexibility in its deployment
  • Glad to see the old card still available for a small £ saving
  • PCIe Gen 3×8 is excellent and more than this card needs
  • No inclusive DAC type cables, even as an optional purchase
  • Not Supported outside of NAS, so you will likely buy 3rd Party Cards for your client hardware – so might be easier to just buy +1 of those

Synology SSD Caching and Combo Upgrade Cards

In the latest desktop NAS releases from Synology, we have seen the appearance of dedicated M.2 NVMe slots that allow you to install super-fast PCIe based SSDs inside, which you can then combine with your slower (but larger capacity HDD RAID) in a system known as caching. In brief, this utilizes the much, much faster SSD access speed towards storing copies of more frequently accessed data (typically hundreds/thousands of smaller files) and thereby improve performance – both in general feedback/utility and general Read and Write. Older generation devices before around 2017/2018 (which the exception of around 2-3 devices) did NOT arrive with this feature and in efforts to allow users to have this feature, Synology has released a couple of versions of this hardware in PCIe add-on form. The latest of these is the M2D20 2xNVMe card (also supports the larger 22110 M.2 SSD too). Support and compatibility on your NAS are more centred around the CPU inside than the PCIe, but this has allowed a number of users to take advantages of the improvements in caching that are being rolled into DSM 6.2 and DSM 7.0. It is also worth highlighting that the previous generation of this card, the M2D18, is still available and is a PCIe Gen 2×8 version that is better suited to the 2016/2017 series Synology SMB systems, though only supports to 2280 length m.2 SSD. Synology NAS users could always choose to occupy their available SATA SSD bays and use SATA 2.5″ SSDs, but these do not quite provide the same level of boost and still require you to lose an available storage bay. See a little more on this in the video below:

However, in mid-2020 the next generation in this hardware arrived from Synology in the form of the new E10M20-T1 PCIe Card. This PCIe Gen 3 x8 card provided 2x 22110 M.2 NVMe SSD bays for caching AND it included a 10Gbe Copper ethernet port TOO! This card allows users to enjoy super-fast caching AND 1,000MB/s external connectivity AND only use a single PCIe slot. This is especially useful, given the bulk of SMB solutions that had neither of these features would typically have only a single PCIe upgrade slot available. If you can spare the budget, I STRONGLY recommend choosing the E10M20-T1 over the M2D20 (even after the price increase). As usual, it is worth highlighting that 1) the card only officially supports Synology’s own SNV3400 & SNV3500 SSDs and 2) you cannot use this card in a NAS system that already has m.2 slots (i.e you cannot add this and have 4x NVMe SSD slots. Still, it’s a very well made card and highlight recommended for significantly boosting an older generation SMB NAS that can get a PCIe upgrade.

Currently Available SSD Cache and Cache+10G Combo Cards

M2D18 2x NVMe 2280 Card – $169 M2D20 2x NVMe 22110 Card – $219 E10M20-T1 2x NVMe 22110 +10G – $289

Pros & Cons of Synology SSD and SSD+10Gbe Upgrade Cards

  • M2D20 & E10M20-T1 both are PCIe Gen 3×8 and support 22110 M.2 NVMe
  • 5year Warranty on both cards
  • Easy Install and No Drivers Needed for Instant Ue
  • M.2 ONLY Card is too close to the M.2 SSD+10G Card in Price to Justify
  • Lack of ability to use the NVMe M.2 Slots for Storage Pools

Synology DSM vs QNAP QTS NAS 2021 Part III – Backup Tools, Surveillance, Virtual Machines and Conclusion

11 juin 2021 à 16:00

Synology DSM vs QNAP QTS NAS Software & Hardware Comparison

Welcome back to the final part of my Synology vs QNAP NAS comparison, where I go through the main differences between the two biggest brands in the world of NAS in 2021/2022. So far we have covered the brand’s rhetoric, the hardware, the graphical user interface (GUI), how they approach storage, mobile applications, multimedia sharing/streaming and desktop clients! In this final part, I will be moving into much more business-led subjects to compare the Synology DSM NAS systems and the QNAP QTS NAS devices and then conclude with which areas either brand excelled, failed or are identical. Both brands have a fantastic range of backup tools for home users to enjoy (with Synology Hyper Backup and QNAP Hybrid Backup Sync being the too most popular of course), but we are seeing a real emergence of cloud integration on either platform, as software as a service (SaaS) grows in viability – with either brand shouting loudly how they are the perfect bare-metal system to run parallel (bare metal = hardware server that is sync’d with your cloud services, among other things). So today I want to discuss their support of SaaS services, Virtual Machine self-hosting and migration from the likes of VMware and Hyper-V and a better look at Surveillance on each platform, AI-supported services and more. It is ALOT to pack into our final part before we conclude, so let’s get started.

LINK to PART II – Storage Control, Mobile Apps and Multimedia


Synology DSM vs QNAP QTS NAS Software – Backup Tools

This is an interesting area to compare the Synology DSM and QNAP QTS NAS Software and services, as although at a balance it looks like the two brands provide the same functionality, there are a few tiny differences that (if you are not aware) may annoy yours later. As touched on early, the Synology NAS platform arrives with Hyper Backup and Active Backup Suite, whereas QNAP arrives with Hybrid Backup Sync and Hyper Data Protector. BOTH Synology and QNAP across their respective two apps each provide support of:

  • Multi-site backups that can be scheduled, have filters applied, utilize deduplication and support NAS-to-Cloud/NAS/USB/Folder operations
  • Can Backup VMs from VMware and Hyper V and (in the right format) restore the VM image on the brand-specific VM app on either brand NAS
  • Support Version retention on regular bare metal backups and VM backups
  • Guide you through a 3-2-1 Backup System using 1st party resources and applications only
  • Supports numerous backup protocols/methods that include RSync, RTRR, Differential backups and TCP BBR

So, that just about covers 95% of traditional and most frequently asked backup methods. However, this is where the brand’s differing ideas of what users want/need step in. The Synology Backup applications are definitely the better looking of the two, with the Hyper Backup tool being the more chewable/easy one of the two, supporting quite a few cloud platforms (which obviously giving their own C2 service a decent bit of space – can’t blame them), and active Backup Suite ramps things up a bit for business, allowing a larger degree of business targets/sources to implemented. One particularly attractive feature of Synology Active Backup Suite is the Google Workspace and Office 365 addons that are license-free (ie provisionally free) that allow you to connect and sync your cloud software services with the NAS to act as a SaaS local syncing system (besides subscription costs and security, internet downtime is the biggest Achilles heel of Office 365/Google Workspace). This is available on QNAP too (with BoXafe) but requires additional license fees for cloud connections. To counter this, although both Synology and QNAP support inline deduplication, the QNAP ZFS based QuTS Hero platform provides it to a much better degree right now, with additional QuDeDupe software and inline compression too (with saving in data being visible analytically) and even handles encrypted backups better with localized client software that you can install on your business devices.

There are lots more that could be covered here (Synology Drive and its client apps, QSync Pro and its improved mobile client-to-NAS services, etc) but these are when we move into the subject of synchronization, file streaming and are less about backups and more about remote level access and synchronicity in your storage. Although the QNAP Software is still very good for numerous backup methods, ZFS and its file transmission benefits still shine and the support of more kinds of 1st/3rd party external storage and cloud are available – the Synology Backup tools and services are a tad better divided between home and business needs with which services are included in Hyper Backup and Active Backup Suite respectively.

Why Choose Synology NAS? – Active Backup Suite, Hyper Backup, Licence Free Office 365/Google Workspace Sync and Synology C2

Why Choose QNAP NAS? – Hybrid Backup Sync, Many More Cloud Services Supported and Hyper Data Protector has Better Retention Policies


Synology DSM vs QNAP QTS NAS Software – Surveillance

Many users who are on the verge of buying a new NAS drive for home or business will often justify the purchase (to themselves or their finance manager) by factoring in that alongside the backup software safety, the multimedia streaming potential and potential saving versus long term cloud storage by ALSO considering using it as a Surveillance system. Both Synology and QNAP provide a genuine business class surveillance software package with their respective systems that allow you to utilize numerous IP Cameras, IP Speakers, network door locks and bring it all together with a single standalone security deck/feed that can be accessed locally over the network or remotely over the internet. Although both brands have done an incredible job with their respective software, over recent years we have seen a real divergence on how each brand has proceeded in their respective software. One very, VERY clear difference is that QNAP Surveillance gets spread across browser and local client app (windows, mac, phone, etc) less evenly, with adding cameras, extensively changing camera alert functions and customizing the setup being almost exclusively done in the web browser GUI but the local client allowing full camera access, PTZ control and actioning being almost exclusively on the client apps. Whereas Synology and Surveillance Station allow ALL of this to be done on the browser client and MOST of it to be possible on the desktop client app too. The Mobile client for QVR Pro and Surveillance station is a little more limited, but in terms of full software access,  think the Synology platform keeps it a little more even. Here is a breakdown of the main benefits/PROs of each surveillance NAS software:

PROS of Synology Surveillance

PROS of QNAP Surveillance

Considerably Better Browser Access & Controls

Beter 3rd Party Software integration with the Surveillance station API

Better Camera Feed Accessibility in the Browser & Clients

Fast Search Runs remarkably Smoothly

LiveCam converts a Mobile to Live NVR IP Camera Feed

Share Live Feeds to YouTube for Fast/Easy Sharing

 More Camera Licences (8x in QVR Pro)

Technically 3 Surveillance Platforms to Choose that vary in complexity

Better Client App Control and Analytics

Local KVM (Keyboard/Video/Mouse) Support

AI Surveillance services can be added on Integrated CPU NAS, Google TPU card or a GPU Card

USB Web Camera Support

CONS of Synology Surveillance

Only 2 Camera Licenses included

AI Surveillance Services are ONLY available on the DVA3221 NAS

Practically no KVM setup on Diskstaiton NAS systems

CONS of QNAP Surveillance

QVR Elite for QuTS Hero Only has 2x Licenses

Camera Feeds Cannot Natively be used and controlled by QVR Pro in the Browser

Bulk of AI Supported Services are Annual Subscription Fee-Based

Straight away, despite a rocky start, QNAP and QVR Pro grab a lot of the PROs back with their QTS QVR Pro version arriving with 8 Camera licenses (at the time of writing) which is massive compared with the 2x that Synology provides (bear in mind, a camera licence will cost between £30-50 depending on how big a multipack you buy). Likewise, the support of keyboard, video and mouse (thanks to QNAP NAS having HDMI on a large % of their systems) provides the means to interface with the system for surveillance if your network fails and the recordings are needed. Finally, a big, BIG appeal is that the AI-supported surveillance services that are growing in popularity in modern business class NVRs are available on QNAP NAS that has a decent enough embedded graphics CPU (i.e. an i3 and above), the google TPU M.2 Coral upgrade or a graphics card installed – whereas Synology has locked AI surveillance into ONLY two of their NAS systems that have a GPU card installed by default (and cost ALOT). These AI-supported services are pretty niche of course (facial recognition, people counting, zone management and object recognition) but still. many will find this hugely appealing. Here is my video breakdown comparing the two popular surveillance services for QNAP and Synology:

It is worth highlighting however that the AI-supported services on the QNAP QVR Platform are not technically ‘completely free’ and before you think that the Synology DVA3221 near £2K box is an overspend, it is worth highlighting that in order to use all the same AI-powered services on the QNAP NAS platform, you will need a NAS that either has a decent embedded CPU (starting at just over £1K for the QNAP TVS-472XT to start with) and/or a GPU card installed. Then you have to factor in the licences. Not just the camera licences (although both the DVA3221 and any QTS NAS have 8 camera licences for adding camera) but the license to use the AI services on the QVR Surveillance software. Somewhat annoyingly, QNAP has put each of the AI services (tracking faces, people recognition, AI recording analysis, Smart AI Door unlocking, etc) behind individual licenses that (for the most part) are all ‘annual’, so you will need to renew them (see below for current pricing and terms). This is quite a bitter pill to swallow in the long term and although the saving versus the Synology DVA system seems good at first, if you want to run a 4 Bay AI-Powered Surveillance system on the QNAP NAS system with 4-8 cameras, it ends up costing just as much (maybe even more once you factor in the annual fees) and only partially mitigated by the flexibility of the system you want to use.

Overall, it is pretty clear that QNAP gives the end-user ALOT in terms of surveillance for their money (although that licensing model structure gets a thumbs down from me), as well as allowing access to many modern AI CCTV services that Synology either choose to not pursue or only allow on a select few systems. Maybe you are reading this in the future and Synology have opened up this logic to allow ‘Synology supported GPU Cards’ to be installed, which would certainly give this comparison a different outcome, but there is no denying that the QVR Pro surveillance platform allows more flexibility in its setup. Alongside this, the QVR to software right now has a lot more camera licences included (though this drops to x2 on QVR Elite on the QuTS Hero platform – which though admittedly has higher performance on the local client integrated, is a bit of a shame) and many will end up seeing the potential savings being enough to overlook that Synology Surveillance station is the better Surveillance tool in terms of the GUI, supported service add ons and in how user-friendly it can be.

Why Choose Synology NAS? – Better Surveillance Software Overall, Especially in the Web Brower GUI

Why Choose QNAP NAS? – More Camera Licenses, QVR Pro has KVM Support, Wider AI Surveillance Support and Upgrade Options


Synology DSM vs QNAP QTS NAS Software – Virtual Machines

It wasn’t such a long time ago that the use of virtual machines (VMs) was exclusively in the business sector. The ability and utility to create a virtual and remotely accessible version of a computer (giving you need a terminal in order to utilize them in most cases) was simply not of use to the average home or even small business user. However fast forward to 2021/2022 and you find that they have accelerated in popularity, thanks to businesses requiring centralized data storage for both the convenience of duplicating computers AND to simplifying the backup/restore process. Then you have the simple appeal for prosumer or small business users to be able to create an emulated version of their own computer in order to access it anywhere in the work, run test with software/updates that they are hesitant to run on their core system OR simply to allow them to create an accessible VM of an operating system that can be run parallel to that of the core hardware (i.e. a Linux/Unbuntu VM that runs in a window, on a Windows/Mac matching). Most high-end business users in recent years have used one of two popular 3rd party client TOOLS for this, VMware vSphere and Hyper V (with other smaller tools like VirtualBox popping up). Where a NAS can be integrated into this is actually pretty cool, such as:

  • A NAS can be used as a backup target (with versioning, snapshots, etc) for the virtual machine, so you have a local restorable copy
  • A NAS can be used to run the core VM files as a remote target, whilst still using the 3rd Party Software
  • A NAS can have the 3rd Party VM data sent over to it and then the NAS can host the Virtual Machine in its very own premium VM Software
  • A NAS Can combine all three of the above to create a backup access point to a VM (in supported formats and correctly imported) that allows remote accessing VM users, in the event of disconnection or forced restoration, to switch over to the NAS based VM and continue working

Now it is worth highlighting that BOTH Synology and QNAP have excellent VM hosting applications, in Virtual Machine Manager and Virtualization Station respectively, which perform all of the above services, however, they do it in slightly different ways (involving other applications in the system that are integrated) but for VMware/HyperV, the restoration is arguably handled smoother with the Synology Virtual Machine tool and Active Backup Suite tool working together to allowing exclusive integration with Synology Virtual Machine Manager (VMM) as the temporary disaster recovery solution allows you to instantly restore services to the Synology storage server even when the production environment is down. QNAP have very similar services to this, but not the same fast, easy and integrated pass-over system. For a better understanding of the GUI of Synology Virtual Machine Manager vs QNAP Virtualization Station, take a look at the video below:

There are several very unique and arguable superior elements to the QNAP VM software that are worth highlighting. First off there is access to a VM marketplace from within the app that allows you to install Virtual Machines directly on the QNAP NAS without having to obtain the VM Image/ISO independently. These include firewall and network management virtual images such as Pfsense, RouterOS and Zabbix, but there is also a 3-click Windows VM installation option too. This allows users who just want to try out a Windows 7/8/10/Server VM before committing fully to a NAS based VM environment for business/home use and includes a 90-day trial (you can use your existing windows registered key/login if you want. Alongside this, there is also the improved VM-to-Hardware integration available on Synology Virtual Machine Manager and QNAP Virtualization station that allows you to connect USB ports to a VM and allow that virtual desktop environment to access physical local USB devices, however, QNAP takes this a noticeable degree further with the support of PCIe-to-VM connectivity that allows you to connect a Graphics card (or other suitable PCIe to that VM architecture) and allow the virtual environment to scale up considerably (perhaps for video editing or gaming, if the CPU is appropriate). Then there is the flexibility of setup on the QNAP, with Virtualization Station supporting a KVM environment and QVM (QNAP Virtual Machine) to allow a NAS with connected Keyboard, HDMI Video monitor and Mouse to have a local VM that can ALSO be accessed remotely too. Finally, QNAP has a dedicated Ubuntu application that allows you to create VMs of version 18, 19 or 20 of Ubuntu (the free Linux alternative to Windows and MacOS) in around 3-4 clicks of the mouse! This is a very rare occasion in this Synology vs QNAP comparison where I can genuinely 100% say that QNAP spent much, much more time working on 1st party support and Synology keeping it a little more openly supported with 3rd parties – though, given the maturity of the likes of VMware, this is understandable. This is also demonstrated on the subject of container image and deployment (if a VM is an entire OS, then a Container is an application or program that is running without an OS to live on to off) where the QNAP platform has its own Container Station application and download center/marketplace and Synology use the industry popular Docker tool.

Synology’s Virtual Machine Manager is a fantastic tool and definitely one that has enterprise users in its sights! With that improved integration with existing enterprise VM software providers in the market, they have made a very clear decision that their free VM software still has a business feel, whereas QNAP has shaped their VM tool to something more accessible for all tiers (though lacking the snap cloud-to-local VM deployment – which is a real shame). Much like AI surveillance on the QNAP platform, a few of the biggest features of Synology Virtual Machine Manager are license/subscription fee-based (which is a shame, but understandable given the target demographic and its scope when FULLY deployed, these include:

Synology VMM


Synology VMM Pro

(License Required)

Supported Operating System Windows, Linux, and Virtual DSM
Cluster Management Included Included
QoS Settings Included Included
CPU Overcommit Physical CPU threads x2 Physical CPU threads x4
Max Virtual Switches 4 4096
Max Snapshots per VM 32 255
VM Share Links per Host 1 16
Remote Replication Plan Not Included Included
Remote Storage Migration Not Included Included
Run VM on Remote Host Not Included Included
High Availability Not Included Included
Live Migration Not Included Included

Overall, it is going to be a case of whether you are coming into the subject of virtual machines as a completely fresh start, coming from a moderately experienced background or are looking for a system to integrate into your already well established VMware or Microsoft VM environment. QNAP and Virtualization station provides a huge array of self-hosted VM deployment options, connecting with numerous 3rd party download centers to easily pull a VM image onto their system, restore an existing VM image, convert VMs into QNAP supported images and then allows you to integrate a greater deal of hardware resources towards them (GPU card, KVM, etc). They are certainly supporting those bigger VM platforms out there and allow backups, snapshots, faster restoration and making big moves into that SaaS and reducing downtime practices that businesses want, but this is where the Synology Virtual Machine Manager tools shine. With a grander focus on those Hyper-V/VMware VSphere established systems and presenting themselves as a failure and support system, they make their integration a great deal easier for companies to choose. They still take a big advantage by allowing a VM live backup to be stitched over to Synology Virtual Machine Manager as a viable recovery and restoration option, which is likely going to be the clincher for many.

Why Choose Synology NAS? – Synology Virtual Machine Manager is VERY intuative, Cloud VM-to-Local VM Migration & Restoration

Why Choose QNAP NAS? – QNAP Virtualization Station supports more OS/Formats, 3 Click VM download & Install, Dedicated VM tools for different VM Images and has Better Hardware Configuration Options Overall


Synology DSM vs QNAP QTS NAS Software – Conclusion

It’s been a very, VERY long road but we can finally look just how Synology DSM and QNAP QTS for NAS (as well as all the hardware and services in between) compare. There has been a long-running theme all the way through that where Synology has focused on FIRST-PARTY (i.e. Synology-brand) software and hardware priority, then supporting THIRD-PARTY services/hardware when they haven’t got a viable alternative in-house – to mixed degrees of popularity. Whereas QNAP has been a much more level playing field where they have released their own innovative hardware/software (occasionally a little too quickly) and singing its praises, but also tried to keep customization and flexibility for 3rd parties as open as possible and shouting loud-and-proud about that too – which can be a tad overwhelming for the less tech-savvy. Both brands have done an incredible job evolve their platforms as much as they have in 2021/2022, especially when Microsoft, Google and Amazon are pouring BILLIONS into the SaaS (and PaaS and IaaS – Platform and Infrastructure as a Service) in order to create entirely streamable ecosystems for businesses, with NAS brands like Synology and QNAP not only integrating with them but also thriving alongside them as a local/bare-metal failsafe.

These are all very lofty ideas and ones that most home or small business users will likely have little time for right now (aside from where NAS fits in with their Google/Office 365 office tools like documents, email and spreadsheets at a pinch) and for those users, who the NAS stands on its own two feet is what is going to matter most. Synology is earning its position in the market as the complete 1st party software and hardware package in 2021/2022, with a genuinely groundbreaking range of available services, but still managing to make NAS accessible for all in DSM 6.2/7.0. That said, the trends we are seeing in those sub-enterprise services that are slowly receding in support of popular 3rd party hardware, software and services, making using a Synology NAS alongside your own existing setup in a frictionless way cannot be ignored and leading some to think Synology is shifting their industry position towards something higher.

QNAP NAS on the other hand, although maybe trying to cover too many bases at once, is still trying to cover as much as it can to appear to their audience. Their support of considerably more 3rd party platforms/software/services, even when they have their own software available, is certainly admirable and aside from rather aggressive pricing on their QVR Pro surveillance platform, are still the better choice for those who want a much more adaptable and customizable platform. Its a pretty understandable fact that most people who buy a NAS will be arriving with an existing collection of software in their daily workflow (Office 365 for docs, Gmail for their email, Plex for their media, Chromebook for their commute, Skype/Whatsapp for their communication, TB3 for their editing, etc) and it has to be said that QNAP keeps a more open platform to adapt a NAS into this mix than Synology – occasionally less intuitively and not without a little setup-friction, but certainly to more customizable results.

Unsurprisingly, I am going to tell you that both Synology and QNAP NAS are good NAS brands and have earned their place at the top of the industry (whilst both making their own respective moves to integrate into the next tier – ie SaaS providers, Hyperscale environments and Boundless cloud storage), but there is no denying that no one brand has managed to do EVERYTHING to perfection. So, if in double, below is how I would recommend QNAP and Synology NAS to you, for each user case scenario and I hope this guide and my recommendations help you with your next big data storage purchase.

Quel NAS Synology choisir ?

10 juin 2021 à 09:00
Par : Korben

J’ai acheté mon premier NAS en 2010 pour un besoin assez basique de pouvoir réaliser des sauvegardes à la maison et éventuellement de m’en servir comme hébergeur de documents. Mon choix à l’époque a été un DS710+ permettant d’avoir 2 disques durs en RAID, que j’ai ensuite étendu des années après avec une extension DX510 me permettant d’ajouter 5 disques supplémentaires.

Nous sommes aujourd’hui en 2021, soit 11 ans plus tard, et mon DS710+ fonctionne toujours aussi bien. Il est évidemment terriblement lent, et ne dispose plus d’aucune mise à jour, ce qui en fait une machine à risque en matière de sécurité. Sans parler du risque pour la préservation de mes données.

De plus comme il est lent et âgé, je ne peux pas, hormis pour du stockage, l’utiliser véritablement pour d’autres besoins autohébergés plus gourmands.

J’ai donc pris la décision d’en racheter un… après 11 ans, faut savoir se faire plaisir de temps en temps. Et évidemment, face à la robustesse et à la qualité de ma première expérience avec Synology, j’ai de nouveau opté pour un serveur NAS Syno : Le DS1821+.

J’y reviendrai après.


Que faire avec un NAS ?

NAS, ça veut dire Network-attached storage. En gros, stockage réseau. C’est donc un ordinateur relié à votre réseau, qui dispose d’une grande quantité d’espace disque et qui peut être utilisé pour tout un tas de choses que je vais essayer de lister ici. Évidemment, l’un des gros avantages du NAS, c’est que son espace de stockage peut être mis en RAID, c’est à dire rendu redondant pour que justement, si un disque dur lâche, aucune donnée ne soit perdue. Et ça c’est cool.

Donc ce qu’on peut faire avec un NAS, évidemment, c’est avant tout du stockage de données. C’est-à-dire des sauvegardes (time machine ou classique), mais également en tant que serveur de fichiers dans les petites entreprises où chez les particuliers qui veulent à la fois partager des documents avec toute la famille, désengorger leur ordinateur de bureau et évidemment ne pas perdre de données.

Au-delà de ça, on peut aujourd’hui faire des tas de choses super cools avec un NAS sans pour autant avoir besoin de mettre les mains dans le cambouis.

On peut par exemple en faire une station de téléchargement qui récupérera pour vous automatiquement les derniers torrents récupérés manuellement ou à travers un flux RSS. On peut ensuite aller un peu plus loin en y installant un Plex ou ce genre de chose pour en faire son propre service de streaming perso. Même chose avec la musique et les MP3.

On peut également l’utiliser pour faire de la surveillance vidéo en y connectant ses caméras IP, y stocker toutes vos photos, mais aussi héberger des sites ou des services pour développer une alternative autohébergée au cloud…etc. pour vos emails par exemple ou pour remplacer Google Docs et ce genre de choses. Et si vous êtes développeur, vous pouvez évidemment vous en servir comme dépôt Git mais également serveur de test pour le déploiement de votre code.

Sans compter sur le fait qu’aujourd’hui, les NAS supportent également Docker, ce qui permet de déployer à peut prêt tout et n’importe quoi en terme d’applicatif sans se prendre la tête, grâce à la virtualisation.

Quel type de NAS choisir ?

Alors je vais parler beaucoup de Synology pour plusieurs raisons. D’abord, c’est le matos que je connais le mieux. C’est également l’une des marques les plus robustes au niveau du matos et les plus fiables au niveau du logiciel. Ça tourne comme une horloge suisse.

Mais vous pouvez évidemment vous intéresser à d’autres marques comme les NAS Qnap qui sont également très bien ou si vous aimez bidouiller, recycler un vieux PC et y installer TrueNAS pour faire votre NAS DIY. Je n’ai pas opté pour cette dernière option qui bien qu’économique, demande pas mal de temps pour choisir le bon matos, mettre tout ça en place et surtout en maintenance au fil du temps pour assurer la sécurité de mes données.

En gros, avec Synology, je paye un peu plus cher, mais je ne me casse pas la tête.

Quel stockage choisir ?

Je parle de RAID depuis tout à l’heure, mais une petite explication rapide s’impose. Le RAID (pour Redundant Array of Independent Disks) est une technologie de stockage de données qui permet de combiner plusieurs disques durs en un seul espace de stockage. Il existe différents types de RAID qui offrent des niveaux différents de performance, de capacité de stockage et de fiabilité.

Je ne vais présenter que les RAIDs qui offrent de la redondance en matière de données. Les RAID 0 et JBOD n’offrent pas de redondance, donc c’est pas ouf.

RAID 1 : Celui-là c’est simple. Les données sont écrites à l’identique sur les deux disques durs simultanément. C’est ce qu’on appelle du data mirroring.

RAID 5 : Le RAID 5 permet de répartir les données sur minimum 3 disques durs et de calculer des données de parité qui seront également distribuées sur tous les disques durs appartenant à la grappe de disques. Ainsi il est possible avec 2 disques intacts d’en reconstituer un 3e à partir des données de parité. Moins d’espace disque perdu qu’en RAID 1, et des temps d’accès plus rapides. Pour faire du RAID 5, il vous faudra 3 disques durs minimum.

RAID 6 : Pareil que le RAID 5, mais avec 2 couches de parité ce qui permet de supporter la panne en simultanée de 2 disques durs maximum. Pour faire du RAID 6, il vous faudra 4 disques durs minimum.

RAID 10 : Le RAID 10 permet d’avoir des performances équivalentes à celle d’un RAID 0 et le niveau de protection des données d’un RAID 1, en combinant les disques durs en groupes de deux dans lesquels les données sont mises en miroir.

RAID F1 : On est là sur un besoin un peu plus particulier, qui équivaut à du RAID 5 sauf que les données de parité sont davantage écrites sur un disque en particulier pour éviter le vieillissement prématuré de tous les disques. C’est un système de RAID à utiliser sur des systèmes utilisant des disques Flash.

Maintenant Synology propose son propre format baptisé le SHR pour Synology Hybrid RAID : C’est celui pour lequel j’ai opté, car il présente certains avantages que je vais vous présenter

À propos du SHR / SHR-2

Le SHR permet de combiner des disques durs de différentes tailles et modèles, ce qui permet de faire évoluer progressivement l’espace disque sans se ruiner. Le SHR permet également de disposer de capacités et des performances optimisées, avec moins d’espace perdu. Et en fonction du nombre de disques durs que vous avez, il peut supporter 1 à 2 disques défaillants en simultanée.

Pour simplifier les choses, le SHR c’est l’équivalent du RAID 5 utilisable à partir de 3 disques, avec d’excellentes performances et beaucoup de souplesse et tolérant à une seule panne. Le SHR-2 c’est l’équivalent du RAID 6, à partir de 4 disques durs, donc tolérant à 2 pannes simultanées.

Si vous hésitez entre le SHR et le SHR-2, optez pour le SHR-2 qui apporte une meilleure protection des données, et des performances d’accès beaucoup plus rapide. Donc à envisager si vous voulez accéder à distance au NAS. Après pour ce qui est optimisation du stockage et espace perdu pour la redondance, SHR et SHR-2 se valent.

Personnellement, je vous conseille donc ce format SHR / SHR-2, car cela vous permet de mélanger différents types de disques durs, c’est un RAID facile à étendre, aussi rapide que le RAID-5 et RAID-6, la redondance est bien gérée donc très peu d’espace « perdu » (quand je dis perdu, vous comprenez évidemment que ce n’est pas vraiment perdu, mais utilisé pour la redondance, donc de l’espace non dispo pour y stocker vos données) et cerise sur le gâteau, si un disque lâche, vos données restent quand même accessibles.

Bref, je vous recommande vivement d’utiliser ce format de stockage si vous optez pour un Synology.

Si vous voulez mieux vous rendre compte des différences entre les RAIDs, je vous invite à jouer avec le simulateur de Synology qui vous permet de choisir des disques durs et un format de RAID et ainsi estimer les différents espaces occupés pour la protection ou le stockage des données.

Les critères de choix d’un Synology

Il existe de très nombreux modèles de Synology et choisir n’est pas toujours très simple. Mais pour résumer, ils ont 2 types de NAS : Les rackables qu’on peut mettre dans une baie à destination des entreprises (gamme FS, SA, RS) et les NAS Desktop pour les PME et le grand public dans la gamme DS.

Je vais m’intéresser uniquement à cette dernière gamme. Chez Synology, ils ont beaucoup de modèles et ce n’est pas forcément simple de savoir lequel choisir. Donc je vais vous aider en passant en revue les critères principaux.

Critère N°1 : Le nombre de baies

Les baies, ce sont les emplacements pour mettre les disques durs. Plus y’en a, et plus vos données seront en sécurité, car mises en redondance correctement, et plus vous pourrez atteindre un espace de stockage important. Synology propose par exemple 2 NAS avec une seule baie : Le DS120j et le DS118, qui n’offre pas spécialement de sécurité pour la préservation de vos données. Si le disque dur à l’intérieur lâche, vous perdez vos data. Évitez ceux-là à moins que vous ne vouliez qu’un serveur applicatif et que vous disposez d’un autre moyen pour mettre en sécurité vos données.

Si vous passez sur un 2 baies, vous pourrez alors avoir du RAID 1 maximum, ce qui consiste à disposer des mêmes données sur les deux disques durs. Ainsi, si un disque lâche, les données restent accessibles sur l’autre disque.

Au-delà de 2 baies, ça commence donc à devenir intéressant, car on peut avoir une redondance plus optimale selon le RAID choisi. Sur du Desktop, vous pouvez monter jusqu’à 12 baies max nativement et au-delà avec les extensions.

Critère N°2 : Les performances de la machine

En fonction de votre budget et de ce que vous voulez faire avec un NAS, il faudra opter pour une machine plus ou moins performante. Synology propose des NAS Desktop avec un CPU 2-Core ou 4-Core, de la RAM qui commence à 2 GB et qui est la plupart du temps extensible sans trop de problèmes. Et certains modèles comme le DS420+, le DS920+, le DS1520+ ou encore le DS1821+ permettent l’ajout de M.2 NVMe pour avoir du cache SSD sur le NAS et ainsi accélérer les temps d’accès en lecture et écriture. C’est top !

Critère N°3 : La vitesse réseau

Si vous optez pour une machine puissante, mais que vous avez un réseau local lent ou mal foutu, vous risquez d’avoir des performances dégradées. Pensez donc bien à mettre à jour votre réseau local si nécessaire et regardez ensuite les différents modèles proposés par Synology, qui disposent de 2 à 4 ports RJ45 à 1GbE permettant de faire de l’agrégation et donc d’avoir des temps d’accès réseau optimaux.

Voilà, au-delà de ça, le reste c’est du détail. À savoir le nombre de décibels de la machine, sa consommation, son poids…etc. Il y a bien sûr des fiches techniques pour chacun des modèles sur le site de Synology.

Les fonctionnalités du Synology

Globalement, en termes de fonctionnalités, tous les modèles se valent puisque dessus, il y a Disk Station Manager (DSM), le système d’exploitation de Synology qui vous permet de profiter des outils Synology et tout un tas d’autres classiques de l’auto hébergement.

Nativement, DSM vous permet donc de faire :

Du partage de fichiers rapide et sécurisé avec notamment File Station qui permet de partager vos documents en choisissant les droits d’accès, aussi bien en local qu’à distance, au travers d’une variété de protocoles supportés tels que FTP, SMB2, SMB3 (chiffré), AFP, NFS et WebDAV, sur tous les OS. Il y a même une fonctionnalité de « corbeille » qui permet de récupérer des fichiers en cas d’effacement involontaire.

De la synchronisation de fichiers avec Synology Drive qui fonctionne comme un Dropbox ou un Google Drive auto-hébergé avec la petite application desktop ou mobile qui va bien. Mais également à l’aide de Cloud Sync qui permet de synchroniser votre NAS avec vos services de cloud en ligne comme Amazon Drive, BackBlaze B2, Dropbox, Google Cloud Storage, Microsoft Azure, OpenStack Swift. etc.

De la sauvegarde soit native avec de la copie de fichiers sur un répertoire partagé ou de la Time Machine pour ceux qui sont sous macOS. Mais également de la sauvegarde complète de vos machines physiques et virtuelles avec l’outil Active Backup de Synology. Synology propose également des outils de sauvegarde pour vos outils Microsoft 365 et Google Drive. Cela permet de conserver une copie locale de vos données stockées dans les clouds.

De la virtualisation avec tout ce qu’il faut pour stocker et gérer des machines virtuelles VMware, Citrix, Hyper-V ou encore OpenStack et bien sûr le support de Docker pour vos conteneurs. Attention à l’architecture de votre NAS car si c’est de l’ARM, tout ne fonctionnera pas à ce niveau là.

Des outils bureautiques pour ceux qui veulent justement auto-héberger certains aspects de leur vie numérique sans se prendre la tête ou offrir des solutions communes à leurs collaborateurs avec des outils comme MailPlus pour l’hébergement de boites mails, Contacts pour centraliser les contacts, un chat pour les discussions entre utilisateurs, le calendrier pour synchroniser les événements, Synology Office pour travailler ensemble sur des documents sans oublier un système de prise de notes. Tous ces outils sont accessibles au travers du web, mais également avec des applications dédiées disponibles sur les stores.

Du multimédia avec la gestion de votre bibliothèque musicale, de vos photos, mais également de vos vidéos sans oublier la possibilité de télécharger des fichiers ou des torrents directement depuis le NAS.

De l’accès à distance évidemment pour vous connecter en toute sécurité sur votre NAS même quand vous n’êtes pas chez vous ou dans votre entreprise, notamment avec QuickConnect. Et pour ceux qui veulent héberger des services, il est également possible de disposer d’un DNS dynamique pour ceux qui changent d’IP afin d’avoir toujours un nom de domaine accessible, même sur une IP dynamique.

De la gestion utilisateur bien sûr ce qui sera utile si vous destinez votre NAS à une PME ou à votre famille. Ainsi vous pourrez créer des comptes users, utiliser votre NAS comme contrôleur de domaine, offrir un espace de stockage limité ou non à chacun ainsi que l’ensemble des outils Synology.

De la sécurité, car oui c’est super important surtout si vous exposez votre NAS sur le net. Synology intègre plusieurs systèmes renforçant la sécurité de votre NAS. De la protection des comptes (pour empêcher le bruteforce de mots de passe par exemple) au firewall, en passant par le SSL, le blocage automatique des IPs suspectes et le routage spécifique des ports pour justement exposer uniquement les services nécessaires. Il n’y a pas mal de choses, et même un outil d’audit qui scanne votre NAS à la recherche d’éventuels malwares, de choses suspectes dans les logs et de problèmes de configuration qui pourrait mettre à mal la sécurité de votre NAS.

Les applications sur DSM

Hormis les applications officiellement supportées par Synology dont j’ai déjà parlé et que vous pouvez installer via le Package Center, il est également possible d’ajouter des dépôts tiers. Pour cela, allez dans « Settings » au niveau du Package Center, puis cliquez sur l’onglet « Package Sources ». Vous pourrez alors ajouter ces dépôts :

Ils vous donneront accès à des applications alternatives intéressantes comme Duplicity, Mutt, TVheadend, ZNC, Adminer…etc.

Quel modèle de NAS choisir ?

Alors globalement, en termes de fonctionnalités, tous les modèles se valent puisque dessus, il y a DSM, le système d’exploitation de Synology qui vous permet de profiter des outils Synology et tout un tas d’autres logiciels. Notez que les NAS sont en général vendus sans disque dur. Dans la suite de l’article, je vous explique quels disques durs choisir.

Un NAS pas cher

Voici une sélection de 3 NAS qui font bien le job et dont le prix reste raisonnable.

Le DS220+ : Le Synology DS220+ est équipé d’un processeur 2 core cadencés à 2 GHz, capables de monter à 2,9 GHz dans les moments nécessaires, notamment en cas de streaming. Il dispose de 2 Go de RAM, de 2 ports réseau à 1 GbE et offre 2 baies pour faire du RAID 1. Vous le trouverez pour moins de 350 euros.

DS218Play : Le Synology DS218 Play est conçu pour le multimédia, permettant un streaming fluide sur tous vos appareils que vous soyez à la maison ou en déplacement. Il gère bien sûr très bien le partage de fichiers et les sauvegardes. Il dispose d’un processeur Quad Core cadencé à 1,4 GHz, de 2 baies, de bons taux de lecture / écriture sur les disques, d’une puce de décodage vidéo (H.265, MPEG 4, MPEG 2, VC-1, support de la 4K, 60FPS max), 1 GB de RAM, des ports USB, un port RJ 45 à 1 GbE et consomme peu surtout lorsqu’il est en veille. Vous le trouverez pour moins de 250 euros.

DS220j : Le Synology DS220J est idéal pour du cloud personnel. Quad Core 1,4 GHz, RAID 1, 512 Mo de RAM, 2 bais, un port RJ 45 à 1 GbE. Il est assez similaire au DS218Play, mais sans la puce multimédia. C’est donc un excellent NAS pour de la bureautique et du stockage de documents. Vous le trouverez autour de 170 euros.

Un NAS performant

Pour ceux qui veulent de bonnes performances avec leur NAS, je vous ai sélectionné ces 3 modèles qui me semblent assez cools pour pouvoir lancer des applicatifs gourmands ou du Docker.

DS720+ : Le Synology DS720+ dispose d’un processeur Intel Quad Core capable de grimper à une cadence de 2,7 GHz en cas de besoin. Il est également équipé de 2 GB de RAM DDR 4, extensible à 6 GB. Vous pouvez y mettre 2 disques et y ajouter 2 NVMe ce qui va grandement booster les temps d’accès (lecture / écriture) à vos données. Vous pouvez le trouver à moins de 760 euros.

DS920+ : Le Synology DS920+ c’est le même que le DS720+, mais avec 4 baies, ce qui permet d’utiliser SHR-2 et donc d’avoir une meilleure redondance pour vos données. Vous pouvez le trouver à moins de 580 euros.

DS1520+ : Le Synology DS1520+ c’est aussi le même que les 2 précédents, mais avec 5 baies et 8 GB de RAM DDR 4, ce qui en fait une machine encore plus performante que les 2 précédentes. Vous le trouverez à moins de 800 euros.

Un NAS avec beaucoup d’espace de stockage

Pour ceux qui veulent des téraoctets et des téraoctets d’espace libre pour stocker beaucoup de vidéos, de photos ou de documents, voire disposer d’un max de machines Dockers, je vous en ai sélectionné 2 qui me paraissent intéressants.

DS1621+ : Le Synology DS1621+ dispose d’un processeur AMD Ryzen quad core cadencé à 2,2 GHz, de 4 GB de RAM extensible à 32 GB et de 6 baies pour y loger vos disques durs. Cerise sur le gâteau, ce NAS dispose de 2 slots NVMe pour faire du cache SSD et ainsi grandement accélérer les lectures / écritures sur le NAS. Niveau débit, vous pouvez agréger jusqu’à 4 liaisons RJ45 à 1 GbE et le NAS dispose également de 3 ports USB 3.2 ainsi que 2 ports eSATA pour y connecter des baies d’extensions. Ainsi, avec 2 extensions DX517 en complément, vous pouvez monter jusqu’à 16 disques. Vous le trouverez pour un peu moins de 980 euros.

DS1821+ : Le Synology DS1821+ est celui que j’ai choisi pour mes besoins quotidiens. Il est identique au DS1621+ sauf qu’il dispose nativement de plus de baies : 8 au total. Il est également extensible avec la possibilité d’ajouter 2 NVMe, la possibilité d’ajouter du support 10 GbE et si vous ajoutez 2 extensions DX517, vous pouvez monter jusqu’à 18 disques. Vous le trouverez pour un moins de 1050 euros.

DX517 : Attention ici il ne s’agit pas d’un NAS, mais d’une baie d’extension qui se connecte en eSATA à votre NAS. C’est un bon moyen d’étendre largement les capacités d’un petit NAS comme le DS720+ par exemple. Vous le trouverez à un peu plus de 500 euros, ce que je trouve quand même assez cher pour une extension.

Un bon NAS qui fait un peu tout ça

Maintenant si vous n’arrivez pas à vous décider et que vous voulez un NAS avec de bonnes performances, un peu de stockage et pas trop cher, jetez un œil à la série des DS4xxx.

DS420+ : Le Synology DS420+ a tout d’un grand puisqu’il propose 4 baies, un processeur 2 core capable de monter jusqu’à 2,9 GHz en cas de besoin, 2 GB de RAM extensible à 6 GB et 2 slots pour y mettre des NVMe. C’est un bon compromis. Vous le trouverez à moins de 500 euros.

DS420j : Le Synology DS420j est également une entrée de gamme avec un processeur quad core à 1,4 GHz, 1 Gb de RAM et 4 baies. Il est silencieux et conçu plus pour des usages multimédias. Vous le trouverez à un peu plus de 300 euros.

La migration de votre NAS Synology

Concernant la migration des données pour ceux qui s’interrogent, sachez que je suis passé d’un DS710+ de 2010 à un DS1821+ de 2021. J’avais un peu peur que ce soit galère, mais en fait, pas du tout. J’ai simplement remis mes disques de l’ancien NAS dans le nouveau NAS. Celui-ci a alors détecté la présence de mes fichiers et a effectué une migration. Y’avait qu’à attendre. J’ai même récupéré ma configuration avec les comptes utilisateurs et tous mes paramètres. 11 ans plus tard, c’est magique !

Quels disques durs choisir pour votre NAS ?

Alors il faut savoir que même si vous pouvez mettre des SSD dans un NAS, ce n’est pour le moment pas très recommandé, car vous risquez de les flinguer. Il vaut mieux rester aux bons vieux disques dur à plateau. Évidemment, les NAS actuels de Synology fonctionnent tous en SATA, et comme ils peuvent accepter des disques de différentes tailles, c’est le bon moment pour recycler des anciens disques et progressivement augmenter l’espace de stockage en achetant des disque de 4 To, 6 To voire plus…

Seulement, tous les disques dur ne se valent pas et certains rendent l’âme plus vite que prévu. Heureusement, Synology propose un outil permettant de trouver les disques les plus adaptés à votre NAS. Seagate, Toshiba, ou encore Western Digital, ils sont tous là.

Pour ma part, je n’ai pas testé les Toshiba, mais j’ai testé énormément de Seagate et de Western Digital et je dois dire que je n’ai eu aucun retour en 11 ans avec les Western Digital alors que des Seagate, j’en ai renvoyé quelques-uns en garantie. Ce n’est pas une étude scientifique que je vous donne là, juste mon expérience perso, donc je vous invite évidemment à faire vos propres recherches. Cela dit, maintenant, je prends uniquement des disques conçus pour les NAS, à savoir des Iron Wolf chez Seagate et des Red Plus chez Western Digital qui utilisent la technologie CMR. Je trouve leur durée de vie meilleure que des disques traditionnels. En effet, ces disques NAS sont conçus pour tourner H24 contrairement aux disques durs classiques.

Concernant le rapport prix / capacité, j’ai fait un petit comparatif perso il y a quelques semaines, et les 4 To sont super abordables… Autour de 100 euros le disque dur. Les 6 To ensuite, ça peut aller si vous voulez investir un peu d’argent. Parce contre, à partir de 8, 10, 12, 14 et 16 To, je trouve les prix encore un peu salés. Donc je préfère prendre un NAS avec plus de slots pour le remplir de 4 To plutôt qu’un NAS avec moins de slots pour y mettre 2 disques de 16 To. Les prix ont le temps de baisser et je pourrais ainsi augmenter la taille des disques progressivement. C’est là, l’avantage du SHR qui permet de mixer les modèles et tailles de disque dur.

Concernant les NVMe que vous pouvez rajouter dans certains NAS pour du cache SSD, Synology recommande essentiellement les IronWolf de Seagate dont le tarif démarre à moins de 75 euros pièce.

Le turn-over des disques durs

Vous pouvez imaginer que les disques durs quand ils sont fortement sollicités, et bien ça tombe plus souvent en panne. En vrai ça dépend des modèles, mais en 11 ans, j’ai du en changer 5 ou 6. Et sur ce nombre, je crois que 4 ou 5 disques étaient encore sous garantie.

Car oui, peu de gens le savent, mais les disques durs ont une garantie assez longue. 3 à 5 ans en fonction des modèles. Donc le turn-over sur un NAS, même s’il est fréquent, n’est pas forcement synonyme de disque à la poubelle et ne vous coûtera pas forcément plus cher. Référez-vous à cet article pour tout savoir sur les garanties constructeurs.

La sauvegarde hors site

Maintenant attention, un NAS à la maison c’est cool, mais pas suffisant pour vos sauvegardes. Si votre maison brûle ou si des voleurs vous prennent votre matériel informatique, vous n’avez plus de backup. C’est donc le moment de penser à de la sauvegarde hors site. C’est-à-dire hors de chez vous. Pour cela il y a plusieurs méthodes. Soit vous mettre un second NAS ailleurs, dans votre famille par exemple, et vous configurer une réplication entre les 2 NAS. Cela peut se faire facilement et nativement avec du Synology. Soit vous partez full cloud… Et là les solutions sont nombreuses. La plus facile d’accès et l’une des moins onéreuses est la solution proposée par Backblaze que je vous recommande également.

Et avec Synology vous pouvez même sauvegarder directement votre NAS sur Backblaze avec l’outil Hyper Backup et ça c’est royal.

En conclusion

Synology propose une gamme assez large de NAS et il y a beaucoup de modèles donc pas faciles de s’y retrouve, mais j’espère qu’avec mon article vous y verrez plus clair. Quoiqu’il en soit, une fois votre budget et vos besoins déterminés, vous trouverez forcément chaussure à votre pied. Tout se joue sur le nombre de baies et sur les performances. Autrement, l’OS et les fonctionnalités restent les mêmes sur tous les modèles. Globalement les Synology sont assez chers comparés à d’autres marques de NAS, mais on paye la qualité du produit qui saura durer dans le temps. Pour ma part, le mien (DS710+ acheté en 2010) ne m’a jamais fait défaut et aura quand même fonctionné sans interruption ou presque durant 11 années. Je compte d’ailleurs encore m’en servir pour d’autres choses plus annexes. Je l’avais également payé assez cher à l’époque, mais finalement, il est depuis largement amorti donc je suis très content de ce choix.

Voilà, j’espère que ce petit tour d’horizon des NAS Synology vous aura plu. À demain !
