Seagate Ironwolf 525 NAS NVMe SSD Revealed

20 septembre 2021 à 15:25

Seagate PCIe Gen 4 NVMe for NAS on its Way – The Ironwolf 525 SSD

Continuing their reputation for bringing new media releases to the market before everyone else, Seagate seemingly has a PCIe Gen 4.0 NVMe SSD in the pipeline for NAS/SAN server use in their Ironwolf series, known as the Seagate Ironwolf 525. Although little is publically know about this new SSD, the Ironwolf 525 has already begun to appear on numerous stock management and distribution sites in Europe, so this seems to indicate a likely release before the end of 2021. Seagate was one of the first brands in storage media to introduce a server dedicated class of SSDs for home and prosumer users (with a U.2/SAS series already in place for enterprise in their Nytro series of course) in both SATA and NVMe m.2, however even in this early leak of information, a few unique or interesting details have already emerged. So, let’s go through everything that we know so far and whether the Seagate Ironwolf 525 SSD will deserve your cache* later in 2021/2022

The Seagate Ironwolf 525 SSD – What Do We Know?

As mentioned, details on specifications of the Seagate Ironwolf 525 NVMe SSD are remarkably thin on the ground. Clearly, release and a formal reveal should not be too far ahead, as even a casual search online reveals that a number of European sites are listing the drive:

As it stands, there are no official datasheets for the Seagate Ironwolf 525 SSD available, but a lot of the specifications that ARE available (across all listing sites), as well as going by the Seagate model ID naming convention used in the Ironwolf 510 and Firecuda seemingly indicate the following:

  • Seagate Ironwolf 525 NVMe SSD
  • Available in 500GB, 1TB and 2TB Capacity
  • PCIe Gen 4.0 x4 Architecture
  • NVMe 1.3 (TBC)
  • 2280 M.2
  • 3D TLC NAND (96L or 176L TBC)
  • 0.98/1.0 DWPD (TBC)
  • 850/1800/3600 TBW (TBC)
  • 1.8M Hours MTBF (TBC)
  • 5 years Warranty
  • Rescue Data Recovery Services (2/3yrs TBC)

Of course, these should be taken with a huge grain of salt until a formal release is made, but even tentatively, compared against the Seagate Ironwolf 510 Gen 3 SSD, the Ironwolf 525 is much more comparable to the Firecuda 520 in architecture and almost certainly will feature the Pison E16 controller. A VERY important factor to keep in mind right now is that in Autumn 2021, there are very, VERY few PCIe Gen 4.0 equipped servers (and practically zero M.2 PCIe 4×4 equipped systems). PCIe Gen 4 upgrade cards are very gradually appearing, but this seemingly looks like it will be a much later winter 2021/2022 hardware change from the big names in NAS, SAN and custom servers. Therefore, as appealing as the Seagate Ironwolf 525 PCIe Gen 4×4 SSD sounds right now, it is worth remembering that very few server systems will be able to fully unlock its potential and if you are considering the Ironwolf 525 for a NAS/Server released before Summer 2021, then you would likely be better off opting for the current Seagate Ironwolf 510 NAS SSD which is PCIe Gen 3×4 and has incredibly high durability taken into account.

The Seagate Ironwolf 525 SSD – Price & Availability

Details regarding when this drive will be available to buy are incredibly thin on the ground. As mentioned, the low number of PCIe Gen 4.0 server systems, the continued high suitability of the Ironwolf 510 and the storage media market that is only starting to bounce back from over a year of shortages (at least!) all add up to the Seagate Ironwolf 525 not being a drive that needs to arrive in a hurry! The current PCIe Gen 4.0 favourite SSD, the Seagate Firecuda 530 and 520 still continue to support the existing PCIe4 client market in desktop and laptop forms, but for NAS (and indeed all server types) this switch is still very much ‘in progress’. Prices however seem to be a little clearer, with individual distributions sites appearing to agree on the pricing for each capacity at the moment of 500GB being €104 (€125 inc.TAX) 1TB at €173 (€208 inc.TAX) and 2TB arriving at €359 (€430 inc.TAX). Of course, these prices are subject to change, but do serve as an early guide on the pricing of the Seagate Ironwolf 525 and how that price sits with the Ironwolf 510 and Firecuda 520 that are currently available. We will keep an eye on this and update you on the Ironwolf 525 as we learn more, so stay subscribed!

SSD Caching On A NAS? What Is It and Should You Use It?

17 septembre 2021 à 01:17

Should you bother with SSD cache in on a NAS?

Most modern generation network attached storage NAS drives include the option of utilising SSD cache, which promises to improve file access and general system performance in a number of ways. Is by no means a new concept and has existed in one shape or form for more than a decade in modern server utilisation. However, in order to take advantage of SSD caching on your NAS, there are a number of hurdles that will often increase the price point of your ideal solution and potentially lower the capacity that you can take advantage of long-term. This leads many users into wondering whether SSD caching is anywhere near as beneficial as brands like Synology and QNAP would have you believe. So today I want to discuss what SSD caching is, who can benefit from it, who definitely won’t and hopefully help you decide whether you should consider SSD caching on your NAS.

What is SSD caching on a NAS?

The majority of NAS systems are comprised of multiple hard drives supported in a single enclosure that are combined together in efforts to increase capacity, performance and redundancy in a configuration commonly known as RAID (Redundant Array of Independent Disks). The more hard drives you have, the larger and more advantageous the RAID configurations you can create. However, these only marginally increase the performance available to you, multiplying performance on hard drives by a factor of the total number of hard drives. Ultimately, you are still using hard drives for your file system which will always pale in comparison to the performance available via solid-state drives SSD but this group of HDDs will result in higher throughput than any single hard drive. The obvious alternative of course is to replace all of the hard drives in your NAS with SSD and therefore reap the benefit of both SSD performance and RAID combination advantages. However, in practice, the main reason that no one does this is that the price point of SSD is significantly higher than hard drives and although the performance benefits would be greatly increased, the price would rise 5-10x times higher at least and the total available capacity would be significantly reduced – as general commercial and SMB SSDs currently max out at 4TB capacity, rather than the 18/20TB available in modern hard drives. NAS/Servers being fully populated with SSDs is still done though on less common setups which are highly enterprise and more commonly known as flash servers – fast but fantastically expensive!

SSD caching was designed as a hybrid storage media solution to this dilemma and involves pairing a small percentage of SSD storage space together with a larger area of hard drive storage space. Typically recommended at around 10% SSD to 90% hard drive, the NAS system will gradually learn over time which files on the total storage system are the ones being accessed most frequently. These files can range from tiny system files, indexes, thumbnails, directories and minor background data, all the way through to larger files that are in shared drives between multiple users, OS-related files that live on a central server and website files that are constantly being referenced for your domain (depending on the I/O configuration of your SSD cache). As the system constantly learns which files are the ones being constantly accessed, copies of these files are made on the area of SSD cache and in future when these files are requested by connected hardware clients, these faster-accessing copies will be targeted instead. Although this is a large oversimplification of the process, it is generally accurate. Not to be confused with tiered storage, which moves commonly accessed files to areas of SSD (not making a copy in 2 locations), SSD cache has numerous advantages and disadvantages that many users would do well to learn before embracing this storage media process. Let’s discuss this a little further, as there are multiple types of SSD cache options available from most modern brands.

What is Read SSD Caching on a NAS?

The easiest but least beneficial type of SSD cache for a mass is read-only cache. This can be implemented with even a single SSD and much like the description above, involves the system moving copies of the most frequently accessed data onto the SSD. Read-only SSD cache on a NAS prevents editing or modifying of files that are being accessed on the area of the cache. Read-only cache is only of benefit to users who are accessing larger databases of preset data that is not often modified and although improves access to these more common files, limits the overall benefits of SSD caching in most NAS systems long term. Also known/referred to as Write-around SSD caching, this too writes data to the primary storage first instead of to the cache. This gives the SSD cache time to analyze data requests and identify the most frequently and recently used data. The SSD cache efficiently caches high priority data requests without flooding the cache with infrequently accessed data

What is Write Caching on a NAS?

Write Caching on a NAS can actually be broken down into two types. The first, Write-through SSD caching, writes simultaneously to the SSD cache area and to primary storage. The cache enables faster data retrieval, while the primary storage writes safely retains the data even if a system interruption affects the cache (eg a power failure). Write-through SSD caching does not require additional data protection for the cached data (so you can use one or more SSD in a Single/RAID 0 Config), but does increase write latency (i.e write time). The alternative is Write-back SSD caching, which writes ONLY to the SSD area first, then confirms that a block is written to the SSD cache, and the data is available for usage before writing the block to the main storage RAID array of HDDs afterwards. The method has lower latency than write-through, but if the cache loses data (i.e. critical system failure, power loss, etc) before the data writes to primary storage, that data is lost. Typical data protection solutions for write-back SSD caching are redundant SSDs or mirroring (i.e. MASSIVELY recommended or enforced that SSDs in a Write Through config are in a RAID 1/5 at the very least).

The application and customization of SSD caching in modern NAS software are incredibly diverse and in most cases, you can create a very bespoke SSD caching config for your system that integrates one or more caching read/write methods taht are best suited to your system setup, data types and access routines. So, now you know what SSD caching is and the types that most commonly exist, what are the advantages and disadvantages?

Guide to Seagate SSDs Guide to WD SSDs

What Are The Advantages of SSD Caching on a NAS?

The benefits of SSD caching on a NAS are often tough to measure, as the resulting improvements are the culmination of multiple smaller improvements at once. So the benefits are more often FELT than actually seen, as latency will be reduced throughout the overall access of the data on your NAS. Compressed data like thumbnails, indexing information and system reference files that a NAS will refer to in a given process will be turned around much quicker in the background and therefore will reduce wait times on instructions given by you to the NAS. Typically larger databases in scale rather than individual file volume will reap the most benefits, and therefore the advantages of SSD caching on a NAS are:

  • Faster Access to Larger databases made up for many smaller files
  • More cost-effective than an all-SSD system
  • Write-Cache/Write-Through Caching benefits more traditional one-way activity
  • Cache is largely self-managed, so once set up, will choose/drop important cached data on its own
  • The bulk of Porsume/SMB and higher NAS hardware arrive with dedicated SSD Cache bays, so no loss of traditional storage bays
  • SSD caching is becoming increasingly available on ARM-powered devices

What Are The Disadvantages of SSD Caching on a NAS?

It is very important to understand that SSD caching is not some kind of magic wand that will suddenly make your NAS significantly faster. Indeed, SSD caching will be of little to no use to the majority of home and prosumer users on a smaller scale, as larger files will rarely be moved to areas of cache and most home users will use a NAS predominantly for multimedia use, large-scale backups and surveillance in home or office environments. Not only do these processes use significantly less frequently accessed data (more likely resulting in the CREATION of new data) but as they are often more ad-hoc in nature, aside from some early write-caching, the benefits of SSD caching will be all but useless to you. Then there is the added cost, added system overhead resource use and more. Here are the main disadvantages of SSD caching on a NAS:

  • Increases Costs of your Storage Setup
  • Not all NAS M.2 NVMe SSD bays are the same bandwidth, some are capped to 1000-2000MB/s, bottlenecking some SSDs
  • Cache Data benefits are HEAVILY dependant on storage user type/files
  • Some Cache methods (i.e Write-Back) store data in the cache, THEN move to the system as it is written and susceptible to loss in the event of a power failure

M.2 SSD Vs SATA SSD Caching on a NAS?

As mentioned in the introduction to today’s article on SSD caching, the majority of NAS drives in the market right now support SSD caching. However, though many have adopted NVMe M2 SSD bays to allow users dedicated ports to do this, many other more affordable or smaller scale NAS hardware systems (2-Bays, ARM CPU devices, etc) still require the end-user to occupy existing traditional hard drive media bays for SSD media for caching instead. Obviously, this can be a significant disadvantage to your overall total maximum capacity when losing main storage bays to smaller capacity SSD for caching. But is there any difference in performance benefits by opting for significantly faster M2 NVMe PCIe SSDs for caching over traditional SATA SSD? Well yes and no. The data stored on the SSD cache has the potential to be delivered to the NAS physical interfaces at whatever maximum speed the SSD can output, so NVMe SSD will always technically push that data faster. Likewise, as the library of cached data and metadata is compiled in the system’s usage, its creation will be markedly faster on the NVMes than SATA SSD which is going to be advantageous to numerous types of write-caching. However, if you are only utilising one or more gigabit ethernet connections, then the difference felt by the end-users when read-write caching is applied between either SSD media type will be practically unnoticeable. Therefore the noticeable differences between SATA SSD and M2 NVMe SSD caching only really apply to use us who take advantage of a larger external network interface or are running larger database operations inside the NAS architecture, containers and virtual machines.

It is also worth remembering that despite many NAS systems releasing with NVMe SSD bays, their architecture might not have sufficient PCIe lanes on the CPU and assigned chipset to allow maximum NVMe SSD performance. In short, not all NVMe slots are created equal and although you may purchase a 3000-4000MB per second SSD for your NAS and its caching, don’t be surprised if that PCIe m.2 physical revision caps your performance much lower (I strip-down of the hardware inside most home/prosumer NAS systems like the DS920+, TS-473A or Lockerstor 4 will show that the M.2 NVMe slots inside can only reach 1000-2000MB/s at most as they are PCIe 2×2, PCIe 2×4 or PCIe 3×2. In short, NVMe SSD slots for caching are a good thing and can certainly provide better performance over SATA SSD in a number of ways, just be aware that sometimes the way you use it or the hardware of the NAS itself will potentially limit this.

OpenSSL Vulnerabilities in Synology & QNAP NAS – What Is Going On?

9 septembre 2021 à 15:06

The Current Synology & QNAP NAS and OpenSSL Security Issues Explained

As many of you may have heard, in recent weeks there were two vulnerabilities identified in the OpenSSL encryption platform, a popular SSL option for many sites and servers, that provided an opening for particularly industrious interlopers to access a site via a weakness in the platform. Although not a service that is developed by Synology or QNAP NAS, it is used in several smaller areas/applications in their respective DSM and QTS software platforms. This is not uncommon for a brand to use a third-party provider and OpenSSL is one of the most popular open-source SSL platforms in the world. This vulnerability in OpenSSL was identified in late August and although alot has happened in that time, though the vulnerability is beginning to be resolved, it is still not fully resolved on the Synology or QNAP NAS affected software and services. So, today I wanted to go through what an SSL is, what OpenSSL is, the nature of the vulnerabilities, what has been resolved, what hasn’t and ultimately explain where things are right now. Let’s get started!

What is an SSL certificate?

You know when you browse the internet and there is that little padlock next to the www.website bit? That symbol indicates that communication between your web browser and the website/server you are communicating with is encrypted. This padlock identifies the SSL certificate, or Secure Sockets Layer and in recent years it has become heavily encouraged that any website you visit has a valid and secure SSL in place (with google warning you if you go to an ‘unsecure’ site and openly recommending SSL engaged sites higher on page 1 of Google. If you are choosing to access your NAS via the internet, then then it is recommended (and set as a default on the NAS platforms in many ways) to access your server via an SSL equipped connection, as this adds a valuable security protocol and creates an encrypted link between a web accessed server and a web browser.

What is OpenSSL?

OpenSSL is a open-source encryption tool/library – released in 1998 and REGULARLY updated, it is regularly used by both Synology and QNAP in a number of their software and services that feature a remote access component. It is not just them and many, MANY others use OpenSSL in PARTS/ALL of the architecture of their remote connections for encrypted data transfers. The use of OpenSSL is by no means a negative mark on any brand, as it has been developed over an exceedingly long time and is regularly updated.

What was the Vulnerability with OpenSSL?

In August, two vulnerabilities in the OpenSSL platform were identified and OpenSSL themselves were contacted immediately. The “CVE-2021-3711” and “CVE-2021-3712” security holes were in the as-then-latest release of OpenSSL and in their own security updates and advisory, were listed as Moderate and Severe in importance. Likewise, OpenSSL (among others no doubt) contacted Synology and QNAP to highlight this vulnerability and each brand added entries into their security advisory and posted on their own platforms about this, adding that they were working on a resolution (almost certainly to be based on the resolution formed and executed by OpenSSL themselves). The two vulnerabilities were still remarkably small and required a rigid-set scenario and knowledge in order to be in any way usable. However, they did open the door to the following negative actions and allowing attackers to:

  • Carry out DoS attacks on the server
  • Execute malicious code into the server
  • Gain remote access to the Server through a buffer overflow.

In the case of Network Attached Storage (NAS) from the likes of Synology and QNAP, it was highlighted very early on that it could only effect NAS systems with internet connectivity. On August 24th 2021, OpenSSL was able to resolve these vulnerabilities, closing the matter and issuing a patched update to OpenSSL that removed them both. However, at the time of writing, both vulnerabilities are listed as ongoing on both the Synology and QNAP Security Advisory page (where they highlight any/all security issues on their platforms that have been resolved/worked on).

What Is Synology NAS Doing About the OpenSSL Vulnerability?

Both Synology and QNAP have been updating their users on the resolution of these OpenSSL vulnerabilities, though both brands have yet to implement a full fix at this time for all vulnerabilities across their software platforms. Given that both brands use a unique/modified version of Linux to create their software and services, a simple application of the OpenSSL fix issued on the 24th August is likely incredibly difficult and modification, application and testing of any resolution needs to be conducted by both internally before a widespread software update is issued. While Synology or QNAP does not provide an estimated timeline for these incoming updates being fully concluded, last month Synology told BleepingComputer that it generally patches affected software within 90 days after publishing advisories. Fairplay to Synology publishing information on this immediately.

Product Severity Fixed Release Availability
DSM 7.0 Important Ongoing
DSM 6.2 Moderate Ongoing
DSM UC Moderate Ongoing
SkyNAS Moderate Pending
VS960HD Moderate Pending
SRM 1.2 Moderate Ongoing
VPN Plus Server Important Ongoing
VPN Server Moderate Ongoing

Indeed, below is a statement issued online from Synology to be.hardware.info responding these vulnerabilities and why the brand is handling them internally this way (translated from German to English):

Synology-SA-21:24 OpenSSL includes two vulnerabilities, CVE-2021-3711 and CVE-2021-3712.

CVE-2021-3711 does not affect most Synology devices as they do not use SM2 encryption by default. Although our NAS devices are currently sold with an affected version of OpenSSL, there can only be said to be a security risk if administrators use third-party software with SM2 encryption.

CVE-2021-3712 addresses specific functionality related to the creation of x509 certificates (used for security protocols such as https) that may cause denial-of-service on the affected device. It is difficult to abuse this as it requires administrator privileges.

Furthermore, the manufacturer emphasizes that the priority of updates is based on the frequency of the affected configurations, the complexity of exploiting the vulnerability and the extent of the potential damage that can be caused. In its own words, it should be sufficient to remedy the aforementioned risks within the usual 90-day period.

What Is QNAP NAS Doing About the OpenSSL Vulnerability?

QNAP stated on their own security advisory last month the following two potential consequences of these vulnerabilities if pushed to their fullest extent:

An out-of-bounds read vulnerability in OpenSSL has been reported to affect QNAP NAS running QTS, QuTS hero, and QuTScloud. If exploited, the vulnerability allows remote attackers to disclose memory data or execute a denial-of-service (DoS) attack. Additionally, an additional out-of-bounds vulnerability in OpenSSL has been reported to affect QNAP NAS running HBS 3 (Hybrid Backup Sync). If exploited, the vulnerabilities allow remote attackers to execute arbitrary code with the permissions of the user running the application.. QNAP is thoroughly investigating the case. We will release security updates and provide further information as soon as possible.

A Guide to Rackmount NAS – Sorted by Size

25 août 2021 à 16:00

Choosing the Right Rackmount NAS – Understanding the Importance of Depth

There was once a time when owning any kind of rackmount based storage and/or computer equipment was squarely aimed at high-end business and data centres. Unlike the desktop PC, laptop keyboard or touch screen device that you are likely reading this on, a rackmount scale hardware device is HUGE, can be noisy and is designed for a 24×7 environment that we once considered business-only in both price and size. However, fast forward to 2020/2021 and we find that because of the advances in both the efficiency and capability of the hardware, that rackmounts are affordable to even the most modest of home user – often rivalling the suitability of a more commonplace desktop/tower device. However, rackmounts are generally very awkward in size – either too long, too wide or too deep for most normal deployment. Luckily most NAS hardware developers (Synology and QNAP more so than most) have provided a huge range of different scaled rackmount devices, that vary in capacity, power and (most important of all for today’s article) in physical size. They have produced so many options in fact, that there are now too many to choose from. So, today I want to look at all of the more compact rackmount NAS servers and help you choose the right one for your physical hardware environment.

Using the Rackmount Size Guide Below

Much like looking at any physical object, there are the typical parameters of measuring scale (generally measures in millimetres or inches), but in the case of rackmount NAS there are also more hardware-specific ways to measure the suitability of a rack mount NAS device. Here are the ones you need to focus on:

Height – This is a figure that is measured in two ways. First is the physical height that is increased as more and more bays are included for storage. Generally 44mm for a 4-Bay, the 88mm for an 8/12-Bay, 130mm for a 16-Bay and 175mm for a 24-Bay. However, they also use the measurement of 1U, 2U, 3U, etc. These correspond to the number of ‘slots’ in a rack cabinet.

Width – In most cases, this is largely identical on all NAS devices, as a rackmount is designed in rows of 4 bays horizontally, at 481mm – but there are exceptions as you will need to factor in rails and if some devices have handles and/or rails pre-attached.

Depth – This is incredibly important and one of the main driving forces behind how rackmount NAS has evolved. In most cases, the more powerful the NAS – the deeper it is (in order to fit in larger CPU+Heatsinks, Increased PSUs and larger internal cooling). The majority of half depth rackmounts on the market arrive with mid-range hardware inside, but recent years have provided quite a few 10Gbe and Large solutions from companies like QNAP and Synology.

Below is a breakdown of the available rackmount solutions that you can sort by their size.

Should You Buy a 2-Bay or 4-Bay NAS Drive in 2021?

26 juillet 2021 à 01:57

Choosing Between Buying a 2-Bay or 4 Bay NAS

For many users who decided to make the switch from subscription-based Cloud services and to their own private NAS server, it can be tricky to understand exactly what they need in terms of storage and power. Network-attached storage NAS has evolved rapidly over the years and now there is a tremendous range of solutions that vary in size and ability to choose from, often resulting in the most expensive servers not always being the most capable. One of the first hurdles that many users encounter when choosing their first NAS drive is choosing between a 2-bay NAS and 4-Bay. With the majority of NAS brands out there offering most standard solutions and across different hard drive scales, choosing between these different sized NAS is not as straightforward as one might think. So today I’m going to talk to you about the differences between each, which one is the best value, their advantages and hopefully help you decide which one best suits your storage needs. Let’s start.

2-Bay vs 4-Bay NAS – Storage, Expandability and Capacity

On the face of it, it seems pretty obvious that a 4-Bay NAS model with its increased storage bays will be the better storage option overall. How on earth can a NAS device that is 50% less in media bays possibly compete?!? Well, in recent years the largest available capacity in hard drives has massively increased and therefore the total potential terabytes available for each media bay has grown drastically. Yes, you could fully populate a four-Bay NAS with 4TB hard drives, but you could always just use a single 12TB hard drive at a lower price per TB in 2021 and regardless of whether you use RAID 0 or RAID1 with two disks, still have a huge capacity in a 2 Bay NAS. Additionally, these days a number of brands provide the same level of external enclosure expandability on both the 2-Bay and 4 Bay NAS systems (eg DS920+ / DS720+ and TS-253D / TS-453D), therefore 2-Bay NAS does not have the lower metaphorical glass ceiling that it once had in terms of additional storage down the line. Indeed, you can even expand a RAID 1 to a RAID 5 on a 2-bay but spreading it over both the NAS and expansion enclosure at once, to provide an excellent way to still increase the storage on your 2-Bay later on and not feel trapped within its dual media design architecture.

However, this is not quite as cut and dry as it appears. Despite the improvements in 2-Bay NAS architecture in recent years, there is always going to be one big day 1 advantage in the flexibility of 4 Bay NAS that 2-Bays cannot really match. That is that you do not necessarily need to fully populate a 4-bay on day one and many users go ahead with just putting two hard drives inside a 4-Bay NAS in a RAID 1 at the start. Not only does this give you exactly the same level of storage and performance that you would find in 2 Bay NAS, but it also allows you to add drives to this partially populated NAS and expand its storage pool from a RAID 1 to a RAID 5, increasing the total storage gradually throughout the lifespan of the system, WITHOUT buying a whole expansion chassis. This allows flexibility in how much storage you use now and how much you need to graduate to later at a minimal cost at the start. In summary, although 4 Bay NAS is still technically the better storage, flexibility and capacity option, a 2-Bay is not necessarily as inferior as it once was.

2-Bay vs 4-Bay NAS – Price and Value

This is an often underestimated factor in choosing between a 2-bay or 4-bay NAS system. Many people assume that a 4-Bay NAS costs more money to buy and even more money to populate. Although this is still technically true, it is hardly any more expensive to operate a 4-bay NAS 24×7 than a 2-bay. As far as actual day 1 costs go, notwithstanding the flexible storage installation mentioned in the previous subject, 4-Bay NAS systems allow you to use smaller capacity hard drives in order to match the same storage on larger hard drives. What this means is that a 4-ay NAS allows you to install four 4TB drives inside in a RAID5 and arrived at a lower price per terabyte than 2x 12TB drives. Depending on how you scale your storage and the number of drives you use, 2-Bay shares and 4-Bay NAS can retail at a similar price point and will differ only depending on the drive you choose and the RAID configuration you opt for.

Likewise, returning to the point of the cost of 4-bays as being more expensive than 2-bays, the newest generation NAS drives will often barely be more than $100-150 difference in their prices between 2 and 4 bays and are largely identical in CPU, Memory and ports in every other way. 4-Bays may seem like a bigger chunk of money (especially for those already feeling stretched on a prosumer 2-Bay) but if you are prepared to perhaps drop the capacity you have in mind 1-2TB  (i.e purchase 4TBs, not 6TBs)  to compensate this price difference, the result will be that your 4 Bay NAS can achieve much higher read and write speeds with more drives being accessed simultaneously, whilst also opening the door to dual-drive redundancy configurations (i.e RAID 6) and will ultimately provide a more responsive, higher performing and data safe NAS for all of your needs.

In summary, the savings available in choosing a two-bay over a four-bay can easily be countered in the grand scheme of things by scaling the capacity or architecture of the HDD you choose to put inside. The money saved in a 2 bay might well be money you need to spend a year or two down the line.

2-Bay vs 4-Bay NAS – Power, Performance and Speed

As mentioned, using 4 hard drives in a RAID 5 will likely provide better performance than two drives in a RAID 1 environment. This performance can be measured by traditional direct read and write activity between your client hardware and your NAS, or it can be measured by the performance of individual applications and services from within the network-attached storage drive itself (i.e the NAS software and services). When looking at buying your first NAS, many will overlook 2-Bay’s simply because of this performance boost available in the 4-Bay alternative models. However, enterprise-grade/Pro hard drives Seagate ironwolf Pro or EXOs) will often provide performance benefits in a RAID 1 environment that can surpass the use of standard hard drives in a RAID 5. Of course, Pro series drives cost $40-50 more per drive, but also have longer warranties, data recovery services, more onboard cache and faster rpm to increase that read and write speed, so you get more for your money ultimately. Additionally, if you plan on taking advantage of 10Gbe, either with a port already on your NAS or as an upgrade down the line via PCIe, then you are much, MUCH better off with a 4-Bay NAS, as a 2-Bay (even if populated with the latest generation SATA SSDs) cannot fully saturate 1,000MB/s.

Finally, it is worth discussing that a large number of modern 4-Bay NAS systems in 2021/2022 arrived with dedicated SSD caching bays. These bays do not replace the existing SATA hard drives and are parallel media bays that allow you to install M2 NVMe SSD to improve the internal performance of your NAS by copying more frequently accessed files partially or fully onto the SSD to reduced access time to these more popular pieces of data. Although a handful of 2 Bay NAS systems have arrived on the market with support of dedicated SSD caching bays (Lockerstor 2 and DS720+), the feature is still more available on foUr Bay solutions and for many users that want to graduate the utility of their NAS from home to prosumer and inevitably into business use, the ability to upgrade internal performance in this way can often sway buyers to opt for a 4-bay NAS.

2-Bay vs 4-Bay NAS – Power Use, Noise and Deployment

Unsurprisingly, the bigger the NAS drive, the more power it will consume. When comparing like-for-like deployments in similar architecture on 2-Bay and 4-Bay NAS, the latter will always use a little bit more. This is the reason that you will generally find that the PSU on a 4-Bay NAS is always of a higher what rating. However overall, unless you are pushing the system particularly hard, the simple act of adding two more SATA hard drives will generally make a minuscule difference and is hardly a reason to compare these two overall – A PSU power rating is the MAXIMUM draw it can make, not the amount it will be using constantly! However, in terms of vibration generated when the system is in operation and the rise in assisted fan operation as usage increases, generates more heat which makes a noticeable impact on the ambient noise generated when you are running a 2-Bay vs a 4-Bay.

The power difference will still remain rather small as these are still quite small components but if you are especially sensitive to noise then the increased drive and fan-based sound will annoy you. Additionally, this increase in ambient noise generation scales accordingly if you use larger capacity drives or more enterprise-level hard drive builds. So therefore if you are looking at a 2-Bay NAS with bigger capacity hard drives, it will still generate a comparable level of ambient noise that a 4-Bay would when populated with standard class NAS media or smaller capacities. Now that brands like Seagate and WD have reshaped their respective portfolios for NAS hard drive media in a way that ALL large capacity hard drive (eg 10TB and above) are Pro class (i.e noisier), it makes the lines increasingly blurry between 2-Bay and 4-Bay NAS noise levels. Below is an example of the noise difference between a standard class and pro class drive noise generation in just a single drive. It may seem a tad irrelevant, but it’s important if you are a user looking to go for a smaller NAS with BIGGER drives:

2-Bay vs 4-Bay NAS – Conclusion

So as you can see, the difference between a 2-Bay and a 4-Bay NAS is a great deal more than the number of available hard drives you can use. Each kind of NAS system can have its performance, capacity, ambient noise and power consumption scaled in a multitude of ways in order to facilitate the best possible network attached storage solution for you. Users on a tight budget might all too soon end up purchasing a 2 Bay NAS without realising that a 4-Bay has scalability that can save you money down the line. Likewise, users who like to invest a little bit more long term or prefer their NAS investment to be a little bit more spread over the lifespan of their product will tend to err towards a 4-Bay solution, without realising that a 2-Bay is still quite viable in the short term and modern scalability of NAS means taht a 2-Bay NAS is not quite the dead-end it once was! Below I have detailed some of the BEST examples of 2-Bay and 4-Bay NAS Synology, QNAP and Asustor that are great examples of margins between each tier has become spectacularly narrow.  If you are still unsure on how to proceed, be sure to take advantage of the free advice service here on NASComapres using the boxes at the bottom.

Best Plex NAS to Buy for over £2000 in 2021

Top 3 NAS Drives for Plex Media Server for £2000

How many of us have decades of media in our homes? Somewhere between hard drives and USB that are full of cinematic enjoyment, collections of boxsets, music cluttering up CDs and hundreds of DVDs all over the place has led to most users sitting on hundreds or thousands of their favourite bits of media. Nevertheless, the convenience of services like Netflix and Amazon Prime video has led many users to abandon this hardware media in favour of watching the same multimedia streamed online. However subscription-based streaming services are far from perfect, with available media rotating and the availability of TV shows changing from month to month, results in a multimedia experience that can be at best diverse and at worst rigidly controlled. This is one of the main reasons that many users have made the switch from paying monthly for the likes of Netflix and switching over to their own Plex media server on a NAS. Aside from the ability to enjoy the media that they already own and grow that collection organically, Plex media server also provides the slick and attractive graphical user interface (GUI) found on those streaming services. Rather than traditional file folder access, a Plex media server NAS will scrape online databases for information such as thumbnails, cast information, trailers, reviews from reputable websites, extra behind the scenes footage and does this using the media that you own! The one barrier that stands between you and your perfect Plex media server is the amount you are prepared to pay for the hardware that the server utilizes and, in short, the scale of the NAS drive you purchase. NAS Drives have fast become one of the most popular ways in which people create their own ‘set-up and forget’ Plex media server and previously we have discussed the best Plex Nas for £500-1000. However in order to truly have a uncompromising Plex media server that will comfortably stream 1080p and 4K media to multiple client devices at once (at a variety of scalable quality levels) requires a noticeably larger investment and today I want to discuss my top 3 NAS drives for £2000 THAT will provide the very best Plex media server for you, your family and friends in 2021. Let’s take a look.

Note – it is worth bearing in mind that a NAS drive will still require you to purchase hard drives and although all NAS drive servers for Plex can run with as little as a single hard drive (and then add more later) this still means that you have to factor this into your budget.

What should I be looking for in a Plex NAS?

Any NAS that is going to be used as a Plex media server needs to have certain hardware and software options as standard, to skip even one of these will severely bottleneck your performance from Day 1. Although most of these are available in more affordable NAS drives, the extent to which they are supported will make all the difference between a good Plex media server and a great Plex media server on a tight budget. (as well as still having money for hard drives). These factors are:
  • An Intel or AMD based CPU that is 64-bit x86 in architecture
  • Support of at least 1080p and 4K regular playback, as well as the support of 1080p transcoding to Plex client devices
  • Embedded graphics or transcoding support (hence that CPU range)
  • At least two Bays of storage (for greater storage and redundancy, AKA – Disk Failure Protection)
  • A frequently updated and stable graphical user interface (such as Synology DSM or QNAP QTS)
  • Support and compatibility for the plex media server application (not all NAS support it, weaker ARM CPU and Unbranded NAS might not)

Rest assured that all three of the NAS drives for Plex that I have recommended below will provide excellent support for these features. It’s no huge secret that any old budget PC, unused Mac  mini or old laptop can run as a Plex media server, but the reason people are purchasing NAS drives from companies like Synology and QNAP for use in Plex is because these devices, even in a budget form, provide the following advantages:
  • Quiet and stable storage
  • RAID functionality for hard drive failure or combined storage
  • 24/7 reliability and efficiency
  • Software and Graphical user interface (GUI) that is easily accessible from a desktop or mobile device
  • Network and Internet access for hundreds of simultaneous users
ALL of these factors are what will ensure your Plex Media Server NAS, (even on a tight budget) will be fantastically capable and stable. So, let’s get on to my top 3 devices for PLEX servers.

Best Plex Media Server NAS for Price vs Performance – QNAP TVS-672X NAS

QNAP TVS-672X, Intel i3 8100T, 8-64GB DDR4, 1x 10GbE, 2x 1GbE, USB 3.2 Gen 2, NVMe Slots, PCIe Gen 3×4, EXT4/ZFS, 2yr Warranty = $1700+

What Said in the TVS-872X Review on 05/2021 – The TVS-672X is a revamp of the older TVS-672XT, which was amongst our top 10 NAS of the last few years. If this was the first time I was seeing the hardware featured on the QNAP TVS-872X, with its Intel Core CPU, 64GB of potential memory, 10Gbe on-board, NVMe equipped slots and USB 10G throughout – I would have been reasonably impressed. Likewise, the scalability in PCIe, storage expansions and network connectivity down the line is also a very valid and positive aspect of this system. But for me, it will always live slighting in the shadow of its Thunderbolt 3 equipped older big brother in the TV-872XT. The software on either ZFS or EXT4 file system is still doing what it does well, finding the line between 1st party apps, 3rd party support, customization and (mostly) getting it right – if occasionally trying to be too big for its boots. The QNAP TVS-872X is undeniably still a great example of the wide-ranging features available to prosumers who want a storage system heavily geared towards high-performance transmission via high-performance media with higher tier hardware at their disposal. It would be misleading to think of this NAS as any kind of significant upgrades over the XT, and the price tag that the TVS-872X currently arrives at (£1700+ / $2400) is perhaps a tad closer to that of the thunderbolt version than can be justified, but with an increasing over-reliance by brands on Xeon based systems, the TVS-872X is one of the most graphically well-equipped systems in the market today. If you are looking for a NAS for video editing, Plex media server, AI-assisted surveillance or virtualisation in a more compact form, the TVS-872X and its hardware has a heck of a lot to offer you.


 

Best Plex Media Server NAS for Expandability and Scalability – Synology DS1621xs+ NAS

Synology DS1621xs+, Intel Xeon D-1527, 8-32GB DDR4 ECC, 1x 10GbE, 2x 1GbE, USB 3.2 Gen 1, NVMe Slots for Cache, PCIe Gen 3×8, EXT4/BTRFS, 5yr Warranty = $1600+
It is fair to say that the Synology DS1621xs+ NAS makes a bold statement in what it is bringing to the table. Synology has been a brand that up until a few years ago traded significantly more on its software than it does on its hardware. Devices like the DS1621xs+ go a long way to dispel this myth in 2020/2021 and what we find here is an exceptionally well-equipped desktop NAS system. Obviously, at this price tag, you would expect it to deliver a lot and as a combined hardware and software package, the DS1621xs+ certainly achieved this. What issues you can make with the hardware are of the DS1621xs+ are more a question of the brands own decisions on what users want in storage right now. Small factors such as the NVMe bays not being accessible for RAW storage, the lack of Synology hybrid RAID and the use of CPU seen in 2017 and 2018 release hardware might put some potential buyers on the fence. But ultimately if you’ve committed to a desktop Synology solution because of DSM, the brand’s high reputation and that spec sheet – you will genuinely struggle to find a more powerful and equipped desktop NAS from this company right now.


 

Best Plex Media Server NAS for EVERYTHING 4K and 1080p – QNAP TVS-h1288X NAS

QNAP TVS-h1288X, Intel Xeon W Series 6-Core, 16-128GB DDR4, 1x10GbE, 2x 10GbE, 4x 2.5GbE, USB 3.2 Gen 2, SATA HDD+SATA SSD+NVMe SSD, 3x PCIe Gen 3×4 Slots, EXT4/ZFS, 3yr Warranty = £2500+
What we Said in our TVS-h1288X Review on 11/2020 This is, hands down, the most impressive desktop NAS drive I have ever handled – and I do not say that lightly! QNAP has been working overtime these last 2 years to not only introduce their ZFS series to the SMB and Enterprise marketing, with gradual but compelling results – but it is only now in the TVS-h1288X system that they have successfully merged it into another core area of their business – content creators. Whether you are on board with the ‘optional thunderbolt card’ nature behind this device, you cannot fault the sheer weight of hardware on offer here and how it is perfectly tuned and appropriate for the storage, performance and safety benefits of ZFS in QuTS Hero included with this device. Yes, it is a hungry beast of a device in terms of power, but right now THIS is the NAS system to beat in the market right now in desktop form. There are still the odd hurdle for surveillance users to jump and the fact this range starts at 8/12-Bay is an odd choice – but with a 6-core Xeon processor that features high grade embedded graphics, upto 128GB of DR4 ECC memory, 3 storage tiers of scaling speeds, a combined external bandwidth of 30 Gigabits per second (so 3,000MB/s) and that is without even the inclusion of a Thunderbolt update that can allow upto 4 more Thunderbolt users to enjoy simultaneous access for photo/video editing – You simply cannot fault the ambition behind the TVS-h1288X and it leaves most of its 8-Bay competitors in its dust – just maybe raid the piggy bank before you buy it though


It is worth highlighting that regardless of which NAS drive you buy, all three of these devices can do so much more than that, providing you with the following additional software and support options to you, your family and colleagues:
– Multi-tiered backup options for Windows, Mac, Android and Linux devices.
– Synchronisation and migration options for NAS to NAS, cloud to NAS, USB to NAS and Apple time machine.
– DLNA media support for enjoying all your media across all your devices
– Multiple user support that allows simultaneous file access and control over the network and internet.
– Privilege, time limit, password and remote share options for sending files to those that need them
– A wide range of third-party apps support from dedicated app centres via the NAS GUI
– Multiple mobile apps available from iOS and Android, that are free and tailored to different file requirements
– Dedicated surveillance software that allows you to connect access and control multiple pan tilt zoom IP cameras in your network environment and record footage, Taylor alerts and set recording rules
– all arrived with two to three years of manufacturer’s warranty worldwide.

Choosing Between ZFS and EXT4 for your NAS Drive in 2020

If you have purchased or are thinking of buying a new NAS drive, it is becoming clear that setting it up in the perfect way is a little more complex than it used to be. You can go for the ‘recommended’ settings, but chances are that those ‘defaults’ won’t fit your storage needs. One of the first decisions you will need to make if you NAS is Intel/AMD powered is choosing your file system. This is non-reversible (without re-formatting all your storage) and therefore is a bit questionable. In 2020, the main file systems of choice in NAS are EXT4, ZFS and BTRFS. We will ignore BTRFS in this article today, as we have covered this alot here on the blog and YouTube (video 1 of 4 below), comparing it with EXT4 many times on the Synology NAS platform. However today with the growth of brands like QSAN and the release of the new QNAP QTS Hero ZFS powered platform, we want to help you make the choice between ZFS and EXT4 when setting up your NAS drive the first time.

ZFS may be the best-known enterprise-grade transactional file system to use storage pools to manage physical storage space. It is not the only one on the market, however. ZFS competes with ext4 for market share in the data management system world.  While both ZFS and ext4 can retain massive amounts of data in a secure, non-cloud storage pool system, the two products are not equal in capacity, management, or usability. Looking at ZFS vs. ext4, we see two distinct transactional file systems. ZFS supports advanced file systems and can manage data long term whereas ext4 cannot. 

ZFS and EXT4 for NAS – Advantages and Disadvantages

While ext4 comes embedded on Linux, it may not be the right choice for managing your data. Consider the strengths of each system in light of your needs.  On the face of it, ZFS seems better but arrives with much higher hardware requirements to run smoothly. Whereas EXT4 has much lower hardware running requirements but has it’s own limitations elsewhere. Let’s shine the spotlight on them both.

What is EXT4 and Why Should I use it on my NAS?

Linux created its original extended file system (ext) as early as 1992. It was the first to use a virtual file system (VFS) switch, which allowed Linux to support many file systems at the same time on the same system. Linux has released three updates since – ext2, ext3, and ext4. Today, ext4 – dating back to 2001 – is the default on the Linux System. EXT4 is also backwards compatible, meaning you can mount it on an ext3, ext2, or ext2 system. Since all these products were created before 2002, compatibility will not be important to most users, however. Ext4 also reduces file fragmentation, improves memory flash memory life through delayed allocation, and can handle larger volumes and files than its evolutionary predecessors. Since the beginning, it has used journaling, a system of logging changes, to the file to reduce file corruption. 

While these components of ext4 constitute an improvement over older extension file systems, the program remains limited in both capacity and engineering quality.  Because ext4 is a refurbishment of technology developed in the early 1990s, it has limited capacity to manage modern loads of data. Its once-helpful journaling system now slows down its processes as it stores more data. Plus, ext4 can support a file size no larger than 18 terabytes, making it a modest storage space for a contemporary data-driven, the digital company moving forward into 2020 (with commercial NAS hard drives from Seagate and WD now arriving at 16TB and growing).

What is the ZFS and Why Should I use it on my NAS?

Many people have heard of ZFS, but are unsure what it actually is. So, what is ZFS? The Zeta File System (ZOL on Linux) is an enterprise-grade transactional file system that uses the concept of storage pools to manage physical storage space. Sun Microsystems began work on the product in 2001 and released it in 2005 as part of OpenSolaris. Even after OpenSolaris was discontinued, ZFS gained popularity since it is a user-friendly, scalable, and powerful data management system. Its strength lies in its simple administration model.  As an enterprise-grade file system, ZFS allows users to create and manage file systems with ease since by eradicating the need to edit configuration files or issue multiple commands. Users can set a quota to limit the amount of disk space used or reserve disk space for a specific file system. 

ZFS uses a hierarchical system layout defined by location- and- conductor-specific sub-module ports each of which is restricted in the locality. Basically, it manages the physical storage of data through storage pools, which allow file systems to share disk space within the pool. When users need a larger storage pool, they add disks similar to adding memory to a computer. As users add storage space, the file systems automatically use the additional memory without the user needing to configure that memory or assign individual processes. This system limits human touch, making it not only easy to use but also highly reliable. 

Most users select ZFS because it offers a simple administration model. Creating and managing file systems becomes easy with no separate volume manager commands to learn. Plus, the system manages mount points automatically. The file system’s low costs let companies create new ones for each project and user, enabling finer data management. ZFS maintains a consistent state for the file system on the disk. Instead of overwriting data, which leaves the file system in an inconsistent state, ZFS manages data with a copy-on-write mechanism. This approach means that neither power losses nor system crashes can corrupt the file system.  A checksum algorithm can verify ZFS’ data and metadata in order to protect file integrity. Rather than performing checksum verification on a per-block basis, ZFS checksums work at a file systems level. The storage pools can self-heal data by detecting bad data blocks and replacing them with a redundant copy. Essentially, ZFS can silently check data and make repairs without user involvement. 

ZFS also offers a built-in snapshot, which can grab a picture of stored data at a precise instant. Users find snapshots quick and easy. Snapshots take up no extra disk space in the pool at first, but as data evolves, they reference old data and thus consume some space. These snapshots prevent old data from slipping back into the current storage pool. ZFS can also send and receive file system snapshots, a process which allows users to optimize their disk space. 

In Summary, ZFS, by contrast with EXT4, offers nearly unlimited capacity for data and metadata storage. It can hold up to 1 billion terabytes of data. To organize that data, ZFS uses a flexible tree in which each new system is a child file of a previous system. ZFS allows users to move these files anywhere and even to attach them to the ZFS on points outside the main point. Users can separate children from parent systems, manage disk space hierarchically, and view the entire tree with a single command.  Basically, ZFS lets data managers organize and control massive amounts of information effortlessly. With one command, users can relocate a sub-tree, backup or mirror a sub-tree, or snapshot a ZFS file system and all its children together. ZFS’ auto-mount feature means files get mounted as soon as they enter the system although users can override this command. Furthermore, it automatically tracks used file space, speeding up the system’s operations and giving users a near-instant update on what’s happening with stored data.

EXT4 vs ZFS for NAS – Conclusion

Users who store massive amounts of data and those who prefer network-attached storage systems (NAS) need an enterprise-grade transactional file system . While ext4 can get the job done, it remains a re-engineered version of a long-outdated system. Ext4 is convenient because it’s the default on Linux, but it lacks the user-friendly, up-to-date approach of ZFS.  Additionally, ZFS has higher hardware requirements for operation and many devices will not have sufficient CPU and Memory available to run ZFS with it’s compression and deduplication advantages. QNAP and their newly revealed QTS Hero file system are combatting this and drastically reducing the amount of hardware needed for their new ZFS based file system platform (making some features like deduplication optional or streamlining other services as needed). However, for many users, you will have to stick with EXT4 and it’s lower hardware requirements.

However, for users with the choice between EXT4 and ZFS, by employing ZFS, users can get a system that automatically reconstructs data after detecting an error , seamlessly combines several physical media devices into one logical volume, has snapshot and mirror capabilities, and can quickly compress data. When considering ZFS vs. ext4, users choose ZFS to enjoy a user-friendly, high-volume storage system that doesn’t need an IT technician to hold its hand.

Recommended NAS for Plex for £1000 in 2021

16 juillet 2021 à 01:10

Top 3 NAS Drives for Plex Media Server for £1000

Buying a NAS for a Plex media server can be a very intimidating purchase. The technology behind network-attached storage has evolved dramatically in recent years and has far surpassed the simple ‘file and folder hard drive over the internet’ image that many associate it with. Modern NAS drives have a huge array of software applications, services, customisable fully featured graphical user interfaces, numerous applications to access your data in the best possible way and, of course, full integration with the popular private multimedia server software plex. That said, not all NAS servers are created equal and much like any piece of hardware, the amount of money you spend on a solution will result in better hardware and performance overall – and a NAS for Plex is no different. Previously I have discussed the best NAS drives for plex for under £500, which all provided an excellent base level of multimedia support but when it came to the handling of particularly dense media, HEVC and in particular 4K, would either reach full resource utilization OR just fail on playback entirely. So today I want to look at the NAS drives for Plex that, although up to twice the price of those mentioned previously, will give you a significant increase in your multimedia playback! Let’s take a look at the best Plex NAS you can buy in 2021.

Note – it is worth bearing in mind that a NAS drive will still require you to purchase hard drives and although all NAS drive servers for Plex can run with as little as a single hard drive (and then add more later) this still means that you have to factor this into your budget.

 

QUICK CONCLUSION

AMD Ryzen V1500B

8-64GB DDR4

= $800

Synology DS1621+

8-64GB DDR4

What should I be looking for in a Plex NAS?

Any NAS that is going to be used as a Plex media server needs to have certain hardware and software options as standard, to skip even one of these will severely bottleneck your performance from Day 1. Although most of these are available in more affordable NAS drives, the extent to which they are supported will make all the difference between a good Plex media server and a great Plex media server on a tight budget. (as well as still having money for hard drives). These factors are:
  • An Intel or AMD based CPU that is 64-bit x86 in architecture
  • Support of at least 1080p and 4K regular playback, as well as the support of 1080p transcoding to Plex client devices
  • Embedded graphics or transcoding support (hence that CPU range)
  • At least two Bays of storage (for greater storage and redundancy, AKA – Disk Failure Protection)
  • A frequently updated and stable graphical user interface (such as Synology DSM or QNAP QTS)
  • Support and compatibility for the plex media server application (not all NAS support it, weaker ARM CPU and Unbranded NAS might not)

Rest assured that all three of the NAS drives for Plex that I have recommended below will provide excellent support for these features. It’s no huge secret that any old budget PC, unused Mac  mini or old laptop can run as a Plex media server, but the reason people are purchasing NAS drives from companies like Synology and QNAP for use in Plex is because these devices, even in a budget form, provide the following advantages:
  • Quiet and stable storage
  • RAID functionality for hard drive failure or combined storage
  • 24/7 reliability and efficiency
  • Software and Graphical user interface (GUI) that is easily accessible from a desktop or mobile device
  • Network and Internet access for hundreds of simultaneous users
ALL of these factors are what will ensure your Plex Media Server NAS, (even on a tight budget) will be fantastically capable and stable. So, let’s get on to my top 3 devices for PLEX servers.

Best Plex Media Server NAS for Affordability – QNAP TS-473A NAS

QNAP TS-473A, AMD Ryzen V1500B, 8-64GB DDR4, 2x 2.5GbE, USB 3.2 Gen 2, NVMe Slots, PCIe Gen 3×4, EXT4/ZFS, 3yr Warranty = $800
What We Said about the QNAP TS-73A Review on 03/21I know I have said this like 10x in the review, but I genuinely respect how mature and focused the TS-473A is, especially when compared with a number of more ‘throw as much hardware as possible at it’ based 8-Bay devices are available from QNAP in their portfolio. A much better balance of internal and external hardware result in a system that feels significantly more capable of business that most devices that the brand have produced in the last 12 months. Add to this that the TS-873A arrives with the QNAP QuTS Hero ZFS platform and you have a system that will tick ALOT of boxes for both novice NAS buyers and more worldly data storage experts. Seemingly taking a leaf out of the books of Synology and their DS1821+ in terms of keeping it straight forward, this solutions sits very well in the portfolio. It would have been easy for the brand to try to squeeze more in, make at the risk of eliminating consumer flexibility down the line and ramping the price up at day 1, but it would seem like QNAP has learned from the odd bit of overstretching in systems like the TVS-872N and TS-1635AX, this time producing a solution that gives the business buyer what they need in 2021, but then allowing them to scale the solution in line with the storage of 2022 and beyond. This is by no means a sexy or exciting solution, for you, I would recommend the TVS-872XT or TVS-1288X. But what you have here is just business, nothing personal.


 

Best Plex Media Server NAS for Expandability and Scalability – Synology DS1621+ NAS

Synology DS1621+, AMD Ryzen V1500B, 4-32GB DDR4 ECC, 1x 1GbE, USB 3.2 Gen 1, NVMe Slots for Cache, PCIe Gen 3×8, EXT4/BTRFS, SHR, 3yr Warranty = $900+
What We Said in Our DS1621+ Review on 10/2020 – Whether you’re looking at buying the Synology DS1621+ as your first footsteps into the world of NAS, or as an upgrade to your existing smaller network-attached storage system, the DS1621+ ticks practically every box. Although some might argue that the hardware might seem almost a little too mid-range, they are missing the point of this device entirely. The DS1621+ is a prime example of everything that Synology is about and frankly, if you love the brand you will love this NAS device. Finding a fair middle ground internally and externally at this price point, the DS1621+ represents Synology doubling down on hardware R&D over the last 2 years and is largely successful in every way. It would have been nice to see a more graphically equipped processor, or something a tad closer in architecture to that of the comparatively powerhouse DS1621xs +, but right now this is the best Synology 6 bay you are going to find and without breaking the bank. The Synology ‘Plus’ series of devices has long held a reputation for providing mid-range hardware to mid-range business customers. Because of this, the DS1621+ needs to balance a fine line between providing fast and reliable hardware, whilst still maintaining a price point that won’t intimidate the average small-medium business user. In this regard, I think the Synology DS1621+ NAS gets it right, finding an impressive halfway point between these two factors. However, it is important for buyers to understand what they are buying and where the budget for the Synology DS1621+ is being aimed. Although it seemingly lacks some of the multimedia and prosumer features of ‘cheaper’ NAS devices in the Synology portfolio, it doubles down on more business and enterprise-level features in efforts to support that core audience. It’s about getting the right tool for the job and in that area, Synology almost completely succeed. The lack of +gigabit connectivity afforded to a NAS unit at this price point, compared with their competitors, may put some users off, but on the whole, you are getting good performance and excellent value on this combined hardware and software solution with some excellent scalability.


 

Best Plex Media Server NAS for All-Purpose Use – QNAP TS-h973AX

QNAP TS-h973AX, AMD Ryzen V1500B, 8-64GB DDR4, 1x10GbE, 2x 2.5GbE, USB 3.2 Gen 2, 5x SATA+2xSATA SSD+2x U.2 NVMe, EXT4/ZFS, 3yr Warranty = $990+
What We Said in Our TS-h973AX Review on 11/2020 – I have seen a lot of network-attached storage over the years and the TS-h973AX brings a lot of colour to what was fast becoming a somewhat grey landscape. In short, QNAP has gone and done it again by proving they are the hardware innovators of this industry and have managed to provide a genuinely unique solution here. When they first revealed their new Hero ZFS operating system last year, you could not help but get the impression that only top-end enterprise businesses with £10K starting budgets were ever going to benefit. The TS-h973AX desktop NAS is solid evidence that QNAP will share the wealth and that this is the start of a whole new series of affordable ZFS solution from the brand. That isn’t to say that this system is perfect and pernickety points about a lack of HDMI or LCD may put off some users, and the compact 9 bay chassis that will attract some will no doubt deter others. Ultimately though QNAP has succeeded in creating what they sought out here and what we find is one of the best examples of hardware and software meeting in the middle, while still arriving with a price tag in 3 figures. In the current absence of a straightforward QuTS license purchase option for existing QNAP NAS systems right now, this is a solution that serves as a good alternative to a number of 4 and 6 Bay solutions in their portfolio. Though, make sure you upgrade that memory on day one!


It is worth highlighting that regardless of which NAS drive you buy, all three of these devices can do so much more than that, providing you with the following additional software and support options to you, your family and colleagues:
– Multi-tiered backup options for Windows, Mac, Android and Linux devices.
– Synchronisation and migration options for NAS to NAS, cloud to NAS, USB to NAS and Apple time machine.
– DLNA media support for enjoying all your media across all your devices
– Multiple user support that allows simultaneous file access and control over the network and internet.
– Privilege, time limit, password and remote share options for sending files to those that need them
– A wide range of third-party apps support from dedicated app centres via the NAS GUI
– Multiple mobile apps available from iOS and Android, that are free and tailored to different file requirements
– Dedicated surveillance software that allows you to connect access and control multiple pan tilt zoom IP cameras in your network environment and record footage, Taylor alerts and set recording rules
– all arrived with two to three years of manufacturer’s warranty worldwide.

Guide to the Best Cheap Switches You Can Buy Right Now in 2021

A Guide to the Best Low Price Switches You Can Buy

If you are looking to buy a new network switch for your home or business needs, then chances are that you have noticed that the prices of these devices fluctuate all over the place. You can pick up a switch for his little as $30 or as much as $1000 and yet they look remarkably similar. Most people don’t even really want to have a particularly fully featured network switch and are just looking for an easy, reliable and cheap switch for the network setup. I have tested and reviewed hundreds of different switches over the last few years and today I want to recommend the best cheap switches you can buy that are still very good. Below I will cover everything from Gigabit to 10Gbe, from managed to unmanaged and from home to business. So if you are looking for a cheap switch that is going to do the jobs you need without fail, there’s a very good chance you will find it below. Let’s get started.

Important – Many of these switches I have personally used, tested for YouTube, reviewed or have found numerous good reviews online. However, I have not selected just the cheapest switch based on just price alone, but rather the lowest price switch that is STILL GOOD – so ultimately the best value network switch you can buy for each environment/setup. There is an important difference between value and low-price, with the former meaning ‘good for the cost’ and the latter being ‘low cost for other reasons’. So, take that into consideration when looking at the solutions below. Additionally, each recommended network switch type will feature an unmanaged option (i.e has no software or graphical user interface via app/computer, everything is fixed in terms of control) and an unmanaged option (i.e features software control, link aggregation, layered security, priority settings, etc). Typically the unmanaged version will be noticeably cheaper and run much more quietly, but the managed switch will have a great degree of control and customizable security and performance.

Best Cheap But Good 1Gbe Network Switch

If you are ONLY looking for an insanely cheap switch that is reliable, setup+forget and one you can get for just a few bucks, then you really are spoilt for choice. For simple gigabit connectivity of up to 5 devices, there are plenty of switches available in the market. However, the key thing to look for is lifetime warranty coverage and to make sure that the switch can handle at least 100MBs for each port – as many particularly budget switch options hide total switching-capacity in the specifications and often will bottleneck when multiple connections are active at once. So don’t ruin things for yourself in an effort to save just $5-10 along the way.

Best Cheap But Good 2.5Gbe Network Switch

Although 2.5Gbe has existed for quite a while, its appearance on the affordable home market is relatively new. Now that we are seeing more motherboards, routers and NAS server drives arrived with 2.5Gbe onboard at the same price as 1Gb, the demand for 2.5G network switches has grown to meet it. There are several different 2.5G switches on the market right now, however many capitalise on the current rarity of this kind of switch and are either overpriced or are cheaper builds that might struggle later. It has to be said that QNAP has really cornered the market in this area and have several 2.5Gbe solutions in their portfolio ranging from highly economical home devices to affordable Business solutions. There are lots of cheap 2.5G switches in the market right now but in terms of the best value for money, I would still recommend the QNAP QSW switches.

Best Cheap But Good Home 1G+10Gbe Network Switch

The demand for combo switches has grown noticeably in recent years, as many users wish to integrate 10Gbe setups into the home office and SMB setups, but do not feel the necessity or budget to fully integrate their entire architecture towards 10-gigabit in its entirety. These combo switches are generally comprised of a bank of 1Gbe ports and then one or two 10Gbe ports for dedicated high-performance network hardware that can be shared by all of the gigabit Ethernet-connected devices. Combo switch devices will either arrive with a combination of fibre and copper connections or will arrive purely in copper 10GBASE-T and 1GBASE-T RJ45 connectivity. Although QNAP and NETGEAR have released several very good combo switches in the last couple of years, some exceptionally well priced 10G/1G solutions have appeared from D-Link and TrendNet that, in terms of price, are near unbeatable.

Best Cheap But Good 8 Port 10Gbe Network Switch

For those that are looking to fully integrate 10Gbe into the network environment, several very affordable pure 10Gbe switches have arrived on the market thanks to affordable component manufacturers like Aquantia (a microchip and SoC manufacturer that was a driving force behind 10Gbe components at 1/10 the price of those before). As desirable and well-placed as Netgear is in the network switch market in 2021/2022, their fully equipped 10Gbe solutions are considerably less affordable than many in the market today and this is perhaps an overreliance on the enterprise market that is starting to wane. Here are a couple of very good switches for those that are looking to completely jump their network to 10G effectively, but as cheaply as possible:

Best Cheap But Good 16 Port 10Gbe Network Switch

If you are a serious business user, someone looking to integrate a surveillance set up with multiple cameras or are managing multiple offices of network bandwidth and connectivity, this is when 16-port switches arrive on the market. The majority of 16 port network switches arrive managed, as at this point a degree of network management is heavily implied. Additionally, many of the switches will be rated as layer 2 or layer 3 security, and depending on your budget or layers of pre-existing security, this may be something you’ll need to look into. Then there is the impact of larger networks and distribution of available bandwidth, with large switches like this allowing unique functionality such as quality of service (QoS), the priority of service (PoS) and vLANs, that allows you to create numerous subnetworks within the larger network. It is network switches like these that just a few years ago would have set you back thousands of pounds and now can be picked up up4 somewhere between $500-1000 if you shop around just right. Here is what I recommend for a higher business class 10Gbe network environment.

Best Cheap But Good SFP+ and Copper Combo 10Gbe Network Switch

Combo switches are designed to allow users to integrate both convenient and localised copper-based Ethernet connectivity along with much more far-reaching and low latency fibre optic connections. Generally arriving with combinations of 1G and 10G connections at the affordable tier, these systems arrived with dedicated RJ45 ports alongside SFP+ transceiver port to allow diverse fibre connectivity. Combo switch devices have also grown more popular with businesses having a central 10-gigabit ethernet NAS in a discreet distant location shared with a large 1Gbe base of hardware – these have now become increasingly more affordable too. QNAP has released some great combo switches in their QSW series and I highly recommend them for those looking at mixed ethernet network environments on a budget.

New QNAP TS-464 and HS-264 Silent NAS Uncovered

5 juillet 2021 à 15:35

Early Sighting of the QNAP TS-464 and HS-264 NAS Drive for 2022

Good news for anyone who is looking to purchase a new NAS and we wondering if/when there will be a new generation of solutions on the market, as QNAP might have accidentally (or at the very least inadvertently) revealed two new NAS solutions coming much, much later in 2021 or (more likely) 2022, with the newly uncovered TS-464 4-Bay NAS and HS-264 2-Bay Silent NAS. These two solutions also seemingly indicate the naming convention for future releases in the Intel Celeron/SMB/Prosumer tier to be X64 and seem to indicate the use of M.2 upgrades, USB 3.2 Gen 2 and more. Practically little else is know about these solutions since their respective uncovering in an official QNAP Livestream for the QTS 5.0 beta on their youtube channel and firmware update notes, but it all looks perfectly genuine. So, let’s dig a little deeper.

What Do We Know About the TS-464 and HS-264 NAS from QNAP?

As mentioned, very little is known about these solutions at this stage and what little we do know comes from 2 key sources online. The QNAP HS-264 appeared on a list of firmware kernel updates on the official pages (see below) and seemingly features the naming convention of the older Silent NAS series (HS-251+ and HS-453DX).

The last real update to the Silent NAS series was back in 2018 and it has always been a popular device, given the silent running and discreet build of this product family. The QNAP TS-464 on the other hand was more publically released on the official QNAP Youtube channel to discuss the ongoing QTS 5.0 beta that is running till the end of July. During the course of this presentation, the subject of how QNAP allow the use of the new Google TPU (Coral) in their systems and how this can be implemented via USB or m.2. Further highlighting that a new NAS coming in the future (the TS-464) will support this feature (see below). It is very unusual for QNA to be so open on new releases like this, whilst the clear unit current-gen device (the TS-453D) is available on sale.

As it stands, these are the few bits of information that have landed, that point at these units. Though there is still information that we can largely be sure of AND a lot we can surmise from these images and the product families. Let’s discuss.

What Should We Expect From the QNAP HS-264 and TS-464 NAS?

Although no hardware specifications of these two NAS systems have been revealed, there is a lot of info we can make educational guesses at. Below is a breakdown of what I think we will see in these two NAS releases:

IMPORTANT – These ARE NOT confirmed specifications and are just based on comparing against other devices in a similar product family OR based on dialogue/images from the QNAP Livestream

Although there is ZERO indication of what the CPU featured in the TS-464, HS-264 or X64 Series actually is, it is moderately well known that the Intel CPU refresh has largely pointed at the Intel N5105 (or much newer) J6412 as the new newer and suitable upgrade. I am much more inclined to believe it is the N5105 however (as indicated below) due to the ease with which QNAP could move their existing setup and manufacture over (As well as the J6412 perhaps being a little TOO new). Likewise, the N5105 has HDMI support and similar memory values and has already started to appear in other desktop servers in the market due for release.

When Should We Expect the QNAP TS-464 and HS-264 NAS to Arrive?

This is a tough one, as 1) this is NOT a lot of information to go on right now and 2) the current generation of the TS-x53D series is still very current and popular. I would be inclined to believe that the TS-464 (and perhaps TS-264 and TS-664 NAS) will arrive more formally and officially in 2022, as the TS-X53D is not get hit by any sharp hardware shortages (aside from the aforementioned CPU refresh hurdle along the way) and performs everything in QTS 4.5/5.0 well. The HS-264 however (I believe) will arrive potentially sooner, as the previous generation silent NAS (HS-453DX) was first unveiled way back in Summer 2018 at CeBit and although has sold well, uses a Intel Celeron chip was already refreshed in that time (J4115 > J4125), Possibly before the end of the year. However, as always, these are estimations and stay subscribed to the blog or here on YouTube to stay in the loop.

Should I still Consider the TS-453D and HS-453DX NAS in 2021?

In short, yes absolutely. If you have been considering the TS-453D or HS-453DX NAS, then do not let the small reveal of the TS-464 or HS-264 NAS systems change your mind. Aside from the lack of any formal release being provided, the TS-453D is still one of the best solutions that QNAP have ever released and its price change since launch, the upgrades that are possible and its performance with the latest QTS software (Surveillance, VMs, Plex, Backups, etc) make it an excellent choice at that price. The HS-453DX may seem a little older, but it is still an unbeatably quiet system, features 10Gbe connectivity, 2 HDD slots and 2 M.2 SSD slots, is still one of the best looking NAS on the market and ultimately deserves the attention it gets.

QNAP NAS QTS 5.0 Beta Now Available

4 juillet 2021 à 23:00

Beta Now Available for QNAP QTS 5.0 Released

Most people who own a NAS drive, for business or for pleasure, will realise very early on that the software that these systems arrive with is more than just simple file/folder storage access. In particular, the QNAP QTS system software and services is one that has evolved a great deal over the years and has now found a good balance between providing a user-friendly experience and providing a good degree of system/storage information when needed. Add to this that QNAP has generally been the first to market when it comes to innovation in the NAS industry (sometimes a little sooner than some might like!) and this has led to them introducing a number of key applications in the past before their competitors in NAS (HybridMount, vJBOD, Container Station, Linux Station and Multimedia Console to name a few) in their previous versions of QTS. At the same time that Synology now launching their new DSM 7 platform (after nearly 3 years in development), QNAP is now going to let users have a test and provide feedback on QTS 5.0. The Beta of QTS 5.0 is now available to download from QNAP HERE and along with numerous background improvements, there are several new applications, new services (that include AI-assisted analysis improvements with the google TPU upgrades) and improved SSD cache handling, security tightening measures. The Beta Test period ends at 23:59 (UTC+8) on July 31, 2021.

What QNAP have said about the QTS 5.0 Beta – QNAP released the QTS 5.0 Beta, the latest version of the NAS operating system. QTS 5.0 has upgraded with Linux Kernel 5.10, improved security, WireGuard VPN support, and enhanced NVMe SSD cache performance. The DA Drive Analyzer, powered by a cloud AI engine, helps predict the expected life of drives. The new QuFTP app helps fulfil personal and business file transfer needs. QNAP now welcomes users to join the Beta Program and provide their feedback so QNAP can further improve QTS and provide a more comprehensive and secure user experience. QTS 5.0 builds upon its solid foundations with an updated system kernel and optimized user interface – followed by enhanced security measures to protect your digital assets, improved system performance to streamline your applications, and integrated AI machine learning to strengthen image recognition and drive failure prediction. Providing cutting-edge features to meet the challenge of rapid technological changes, QTS 5.0 brings you data security, power, and intelligence.

Increase your security level

QTS 5.0 supports TLS 1.3 to improve security and performance, with automatic updates of QTS and apps to ensure your NAS operates under optimal conditions. You can also use SSH keys for authentication to secure access to your NAS, preventing password breaches or similar potential attacks. Previous revisions, TLS 1.2, initializes the connection with a dialogue to agree on a certain encryption type. Once the client and server agree, they begin sharing encryption keys. The reason for TLS 1.3 being faster is because this communication never takes place. Instead, the initial connection is information from the client saying what it plans to access along with supported cypher, key agreements and other information. The server responds with the chosen cypher suite and also a key share. Since the server provides the key right away, the client cannot demand the use of older forms of encryption, hence making the connection more secure. Technically, the client sends all the necessary information to establish a secure connection in the initial ‘Hello message’. It even calculates multiple pre-shared keys based on offered cypher suites. Once the server receives the initial ‘Hello message’, it provides a key to the client based on the chosen cypher suite.

Predict drive failure and minimize downtime with the help of AI

Now you have an exciting solution that can protect you from drive failure and data loss. The DA Drive Analyzer – developed in partnership with QNAP and ULINK Technology – is an AI engine that predicts the expected life of drives, allowing you to take preemptive steps to prevent data loss from predicted drive failure.

Check both the life prediction score and drive health status with a user-friendly interface.

Check the status of all drives in your NAS and expansion units. (TR series expansion units are not supported)

Check each drive’s status on Drive Life Prediction Score. The lower the score, the lower the drive’s health.

Check which day DA Drive Analyzer alerts you on the Alert History tab.

Supports WireGuard VPN for secured internet connection

Your internet and public Wi-Fi connection may put your personal data and privacy at risk. VPN (Virtual Private Network) provides a safe and recommended way to protect your online activity while browsing the internet or remotely accessing your NAS. The new QVPN 2.0 (coming soon!) integrates the popular, lightweight, and reliable WireGuard VPN, providing you with an easy-to-use interface for setting up a secure connection – an especially great tool for home and remote working.

Boosted NVMe SSD cache performance

The new kernel improves PCIe performance, which enables QTS 5.0 to enhance NVMe SSD performance and utilization. When cache acceleration is activated, SSD storage can be utilized more efficiently while also offloading memory resources. It maintains high performance even when multiple concurrent users access the same shared folders, and transferring large-size files via SMB/NFS becomes faster.

QuFTP fulfills personal and business file transfer needs

QuFTP consolidates all FTP related activities into a single app with a user-friendly interface and permission settings for efficiently and securely transferring large amounts of data.

FTP Server

The encrypted SSL/TLS connection provides higher security and protects your FTP transfers. QoS bandwidth allows for setting FTP transfer limitations or speed limitations for users and groups. QuFTP’s rule engine allows more detailed configuration, including access hours, limiting access to only the FTP root folder, adding watermarks to images and videos, and more.

FTP Client

Before activating the FTP client, make sure that your firewall allows connections to the FTP server. You can also create remote mounts of shared folders to make them accessible on the NAS.

The FULL List of Changes in QTS 5.0 Compared to QTS 4.5

Along with the bigger changes listed above, there are numerous other smaller changes in QNAP QTS 5.0 compared with QTS 4.5 for NAS that are worth noting. Some are improvements in compatibility within certain applications and are more noticeable changes in the default lineup of applications are services at launch. Here are the rest of the change notes from QNAP on this new NAS software:

  • QTS now supports Desktop Notice Board, which provides notifications for various events and announcements.
  • QTS now supports TLS 1.3 for HTTPS secure connection.
  • Users can now import custom root certificates to certify the SSL certificate of a server that the NAS needs to access.
  • Updated OpenSSL to 1.1.1.
  • Improved SSD cache design to enhance storage performance. Existing SSD cache will be automatically converted to the new design after QTS update to 5.0.0.
  • File Station now supports displaying thumbnail previews for PDF files.
  • Network & Virtual Switch now supports the DDNS service “DDNS Now”.
  • Added the option to enable or disable strong cipher suites.
  • Added an option to choose whether to redirect users to the NAS login screen when connecting to the NAS IP address without the system port. To enhance device security, this option is disabled by default.
  • To enhance device security, UPnP Discovery Service is now disabled by default.
  • Added support for Content Security Policy HTTP header.
  • QTS now enables the default “admin” account and resets its password when users press the Reset button on the NAS for three seconds. Nevertheless, to ensure device security, we recommend disabling the “admin” account and using a new administrator account after you finish resetting the system.
  • Users in the administrator group now have read/write access permissions for default shared folders, except the “homes” shared folder.
  • Users can now manually specify the time interval and the maximum number of failed login attempts in Control Panel to further enhance NAS security.
  • Qsync Central is not pre-installed in QTS. Users can install this application in the App Center
  • Improved the user interface of Advanced Search in QuLog Center.
  • Added support for displaying the total connection time of online users.
  • QuLog Center now displays computer names and accessed resources in System Access Log and Online Users.
  • To ensure device security, QTS now displays a message to remind users to disable the default “admin” account and to create another administrator account.
  • QTS now displays a message to remind users to enable 2-step verification to ensure account security.
  • QTS Smart Installation Guide now requires users to create a new administrator account. The default “admin” account is disabled after initialization.
  • QTS no longer pre-installs SSD Profiling Tool by default. Users can install this tool in the App Center.
  • To ensure system security, QTS now automatically disables applications that are not updated and that do not meet the minimum version requirements.
  • Removed support for USB printers.
  • Qboost is no longer a built-in application of QTS. Users can choose to install Qboost in App Center.
  • To ensure system security, QTS now automatically disables applications that are not updated and that do not meet the minimum version requirements.
  • Starting from QTS 5.0.0, QVR Pro Client is no longer supported. You can now install QVR Smart Client as the client software for your QVR Pro or QVR Elite surveillance servers.
  • Users need to manually remove and then re-create SSD cache after updating QTS to 5.0.0 beta.
  • QTS 5.0.0 beta temporarily does not support certain file systems on external storage devices. To work around this issue, users can use HBS3 to back up files to external storage devices. Note that this workaround may require more CPU resources and increase backup task duration. We will soon fix this issue in an upcoming release.
  • QTS 5.0.0 beta temporarily does not support the following applications, utilities, or services:

* vSphere Web Client Plug-in
* QNAP SMI-S Provider
* QNAP Snapshot Agent
* KoiMeeter
* Marvell 88SE1475 driver
* Intel QuickAssist Technology (QAT) Driver
* Remote Direct Memory Access (RDMA) Driver
* NVIDIA GPU Driver
* Advanced Network Driver
* Other miscellaneous third-party applications

Which QNAP NAS Drives Support the QTS 5 Beta?

The full range of QNAP NAS systems that support the QTS 5.0 Beta is largely limited to systems that have been released in the 2019-2021 release period, however, they are not limited to the high-end releases, with several ARM-based and Entry-level NAS systems being included. Also, remember that this is a whole system software upgrade and it’s not entirely clear how easy/possible it is to downgrade your system to QTS 4.5 afterwards. I am in the process of deploying this QTS 5.0 beta over on YouTube and comparing it with QTS 4.5 to show you guys how they have changed things up. Stay tuned for that, otherwise, if you want to go ahead and test the QTS 5.0 beta on your QNAP NAS today, you can use the link HERE and check below to make sure you are on the compatibility list.
