Which Backup Method is Best? NAS vs Cloud vs Tape vs USB

23 septembre 2022 à 18:00

What is the Best Way to Backup Your Data Every Day?

I know it is not going to be shocking news when I say that Data is really, really important. That should not come as a staggering fact. If you found this article thanks to a rather perceptive google search, then clearly you think data is very important too. It is all too easy to rely on your data living on multiple machines in your office or home. Centralized backup is a very unappealing idea. For a start, it is expensive. You will spend hundreds, if not thousands of pounds on storage, then you find out that you need to have it in ANOTHER location too (as otherwise, it isn’t truly a backup) and then worse still it isn’t even being spent on making more space, but actually to duplicate your old data and not be used. You are spending all this money on what can be described as a remarkably large insurance policy. Worse still if you have all the machines in your home or office backing up to a device in that same location, almost all data safety and storage experts will scream to high heaven that this is still not enough. Sadly this is true, because not only do you put yourself at risk of complete critical loss in the event of fire or flooding, but also in the case of theft you end up having all your eggs in one basket and making the thieves lives much easier. So ultimate you have to stop thinking about this only in terms of how much this storage is going to cost. If you think like that, you will never move past stage one. No, you have to think about how much will this data cost you to LOSE. Your personal media (family, events, memories), your client’s data or perhaps your surveillance data. Take a moment and think how much it would cost your business right now if you lost your data – hundreds? Thousands? Close the business? The ideal backup solution should always be based on the cost of loss, not gain! Although a little trite, it is still a reliable rule of thumb to have a 3-2-1 backup solution operation that looks like this:

  1. Primary Data (Where data is initially created/collected, the PCs, the Macs, the Phones, etc)
  2. On-site Backup solution (where multiple devices are backup’ed up to internally, also more commonly referred to as the bare-metal backup)
  3. Off-site/different location Backup (where the copy of the on-site backup lives that is separate network and/or physical location. This can range from another NAS, to a cloud provider and even a USB drive)

Stages 2 and 3 should be encrypted in case they are stolen/entered, as well as feature login credentials and an admin system in the event of them being occupied/accessed illegally. Today I want to focus on the 2nd and 3rd stages of your backup routine and help you decide the best ways to spend your budget on the most effective safety net and recovery system for your needs.

Backup and Redundancy – DO NOT GET THEM MIXED UP!

Way, WAY too many NAS (network-attached storage) or DAS (direct-attached storage) owners think their data actually have a backup layer in place when they refer to their RAID configuration, their versioning or their snapshots. These are NOT backup methods and are actually designed primarily as a means of recovering your data in the event of an HDD/SSD dying, an accidentally deleted file or rolling a file back to a previous revision. Think of RAID/Snapshots/Versioning as ‘safety nets’, The only work from INSIDE the infrastructure NOT outside of it. If the NAS server or RAID enabled DAS box does, then there is a very high chance that your data cannot be recovered via these methods (not impossible, just touch and certainly not foolproof). Below is a video that breaks down a number of different Backup and Redundancy methods inside a single NAS system:

How Expensive is a 2-Stage Backup and Do I need it?

The cost of a 2-stage backup (i.e having 2 backups of your data) operation can be measured by the amount of data you/your company produces on a daily basis. Additionally, depending on your commitment to holding onto your data (so, for business, you might have a 6 year or 12-month retention policy) there are ways to make economies in between the stages. However, whether you are a home user of a business user, there are few instances where a double-layered backup is not ideal. Let’s look at this from a business and home user point of view:

Why Business and Enterprise users need an Extensive Data Backup Plan

Example. Your company has 10 employees. Each has their own workstation and they contact clients on a daily basis to drum up new sales, fulfil existing quotes and maintain a customer relationship manager (CRM). You have both #1 AND #2 stage backups (so local PCs and A NAS in-house maybe) covered. Plus you have business insurance in case of a fire or flood. One morning you arrive to find your office has been flooded/burnt/burgled/struck by lightning and everything is fried. At first, you think, lucky we have insurance. They will pay up for whole new office equipment, PCs and your server. However, what about all that customer data? Not only can the insurance company not replace it but they will not pay its consequential value (with VERY few insurance policies covering data recovery services). So now you have to start from square 1. Plus now you also have a bundle of rather angry customers from the previous days and weeks whose requirements go unfulfilled. This coupled with starting your business network from scratch, employees salaries continuing as normal and several IT guys (or 1 guy working for days) setting everything up from scratch again (this WILL be the case from fire, flood or theft) could easily KILL a company. Now, in that context, isn’t a few thousand put towards an off-site #3 Backup so bad? Thought not.

Why Home and Private users need an Extensive Data Backup Plan Too

Ok, so a home user has a smaller ecosystem to maintain and now the mission-critical data and the life or death nature of your information is less so. Or is it? Example #2. What about all those important house documents you’ve scanned? Those TV shows and movies you bought on a one time download? What about your wedding picture or those of your children growing up? Those videos of your friends and relatives that are no longer with us? Not to be bleak, but it is often the case that although much of a person’s data is not of huge financial value, it is still utterly and completely irreplaceable in the literal sense.

Likewise, if your many devices (phones, computers, hard drives) get corrupted, hacked with malware/ransomware or simply broken, don’t you want the peace of mind of knowing that there is always a backup of EVERYTHING? If you are copying the data of all your devices to a large hard drive enclosure in your home, this is NOT a perfect backup. It just protects you from the loss of one or more of your mobile/individual devices. Additionally, the minute you start deleting files on your phone/laptop to ‘make some space because it is already backed up on the NAS‘, your NAS is not a backup, it is the single repository for that data!  So, as you can see, the need for a reliable true backup is paramount regardless of whether you are a home user or business user. However accepting that you need a backup is not enough, you need to know what to consider when choosing the right backup. Home users and their data volume/frequency can always consider USB backups of course, which can be good but only upto the time that the last backup took place AND on the assumption that the USB drive is stored offsite periodically.

What are the factors I need to take into account when considering my Backup Solution?

Choosing the best full backup for your data can be a little difficult. With so many variables ranging from cost to size to speed and more, it can be easy to go around in circles and still end up choosing nothing. In almost all cases, the deciding factor is cost. However, this is closely followed by speed. Having a backup is all well and good, but if it takes too long to finish, it can often be slower than the speed at which you create data and create a bottleneck. Likewise, if you choose an unsuitable connection of choice between your primary backup storage and/or off-site 2nd backup storage, then they may communicate inefficiently. Below are the main overheads to consider when choosing your backup.

Distance & Speed – How far is the 2nd backup going to be from the primary backup and/or primary data source? Unless you are considering fibre cabling between different physical sites, you are going to be limited by your upload/download speed and if your network is busy with multiple users, then you will need to provision priority of service to these backup connections, or else risk it affecting day to day operation (particularly VoIP connections – a growing necessity in 2022 with shifting patterns in the way we are working during/ost pandemic). The local connections between your client devices in-house and the primary backup may well only be using an internet network/LAN to communicate, but that can still become oversaturated. So be sure to provision switches where appropriate too (we will touch on 10GbE later)

Power (Watts etc) – The power of the hardware inside the primary (bare-metal) data storage device, secondary backup target and (depending on your setup) even the power of your client hardware in house is also an important factor to take into consideration when scaling and provisioning an appropriate backup strategy. Critical power failure (i.e a power cut) in one or more of these locations can not only result in some data not being backed up, but more importantly can compromise the backups themselves, with some systems suffering critical hardware failure and SSD/HDD damage in the process. It is HIGHLY recommended for users who are considering a private server for their data have it connected to the mains power via a USB device, in order to allow the system to still operate in the event of power failure AND shut itself down safely.

Physical Media – The server of choice for your primary backup is only half of the battle. The media that you are storing the data too can make a huge impact too. Many have their own maximum speed or capacity, so even with a super-fast enclosure and/or connection, you will be bottlenecked by the drives themselves. All media types e.g. HDD, SSD or Tape have their own maximum performance and some are lower than the connection maximum and some are faster and therefore end up creating a limited speed inadvertently. This can be negated in a number of ways. These range from the use of RAID (redundant array of independent disks) that combines media into single storage pools that benefit from redundancy (i.e a safety net if one drive dies) and/or increases in performance. Additionally, you can look at SSD caching, a service that is particularly popular in private NAS servers released after around 2018 and continues to be included in most systems. SSD caching allows the system to have one of more SSDs installed and then utilize the increased performance they offer to benefit write actions (i.e you write data onto the SSDs first and then the NAS moves it over to the slower HDDs afterwards) and/or read actions (where the most frequently accessed files are cloned onto the SSDs and it speeds up their access to client devices) though this is less useful for backups, it is still a useful option.

The Media connection internally – As mentioned, the SATA port on most commercial HDD/SSD has a maximum of 6 gigabits (Gbs) in SATA III – SAS at 12 Gigabits. All of these are internal and are maximum bandwidths available to each media drive installed in each bay. However, realistically, most typical Hard Drives max out at 272MB/s at the very top end (and even then, this is using enterprise-grade HDDs) and most conventional 2.5″ SSDs (with the exception of U.2 and U.3) max out at about 550MB/s). So you are going to need several of these drives inside your primary backup system in a decent RAID configuration to facilitate performance AND redundancy (like a RAID 5 or RAID 5). For your external/2nd backup target, a lot of enterprise users take advance of cold storage such as tape drive media. Designed to be used for data that needs to be held for insurance/archive for years and years, the current highest generation of tape architecture is is LTO-9 = 400MB/s in uncompressed/RAW form and 1000MB/s in compressed, with storage capacities per tape hitting 45 Terabytes! However, a full backup would take (at best, so with everything at full!) over 12 hours to transfer. Additionally, tape backup is fantastically expensive and therefore largely enterprise only as an option.

The external connection – Lastly and possibly the most overlooked part, is the communication between your primary client devices to send data, the primary backup data and the secondary backup. Not just the speed, but the resilience and future-proofing. You need to consider what connection you are going to use today, tomorrow and years from now. The last thing you want is to saddle yourself with a connection now and later when you upgrade your primary hardware on individual clients or locations, end up with a device you cannot access or use with an unchangeable bottleneck. Then your data just becomes a chore to access at best and potentially days or weeks or time to restore. Popular connections and their speed between host and client devices are:

Network Backups (backups that share a LAN or vLANs in a greater network)

  • 1GBe LAN/Ethernet = 1Gbit/s, or 100-109MB/s
  • 2.5GbE LAN/Ethernet = 2.5Gbit/s, or 250-270MB/s
  • 5GbE LAN/Ethernet = 5Gbit/s, or 500-545MB/s
  • 10GbE LAN/Ethernet = 10Gbit/s, or 1000-1024MB/s

USB and local Backups directly connected and stored offsite

  • USB 3.0 (3.2 Gen 1) = 5 Gbit/s
  • USB 3.2 Gen 2= 10 Gbit/s
  • USB 3.2×2 = 20 Gbit/s
  • Thunderbolt 3 & Thunderbolt 4 = 40 Gbit/s

Fast Local Backups or Direct Connections over large distances

  • Fibrechannel / FC – 1, 2, 4, 8, 16, 32, and 128 gigabit per second rates depending to start
  • Tape Based backups, such as LTO 7,8,9 – 300/360/400MB/s uncompressed and 750/900/1000MB/s compressed
  • Cloud storage – dependant on connection. Additionally, factors such as upload and download speeds, fair usage policies and more affect the performance. If you are fortunate to have a 1 Gigabit internet connection, that means around 100MB/s for download speeds and a fraction of that for upload speeds

So, as you can see, there are many choices out there for a means of sending backup between the 1st, 2nd and 3rd parts of your backup environment.

What is the Difference in Speed and Cost between different Backup Solutions?

And so to the meat of the subject. Different solutions cost money and in the interests of SPEED, below i have detailed numerous solutions that will provide a backup solution of upto 10TB of storage. All Costs and speeds are based on a solution that is an acceptable distance away for maximum efficiency. Perfect speed results were provided with , however, it is worth noting that these are ‘perfect situation’ based and it would be tough to see this maximum threshold. you will comfortably see around 10-20% below this, but that is fine. Finally, it is always worth remembering that the speeds mentioned below are based on an initial 10 Terabyte backup. After that, there is the likely possibility that future backups will be much more granular (this can also be referred to as differential backups, where only the changed files are backed up each time afterwards). But some users may wish to take advantage of time managed backups, where a full backup per day is kept, for X number of days (when eventually the newest backup will overwrite the oldest on rotation).

ALSO IMPORTANT – In all examples where a 4TB SSD (which average around £350-400 over SATA) is mentioned, you can use a 4TB HDDs at around £75-100 (brand depending) to save a considerable sum – but you will effective quadruple or more the time the initial backups will take. Likewise, future incremental backups will be significantly reduced also.  In examples where the SSD would have been substantially bottlenecked by a connection, I have used HDD as you will not need to spend the extra.

The Best Value 1/2.5GbE based Backup Solution for 10TB of data

For a solid LAN based backup (with optional internet access as needed for off-site work) I would recommend the Synology DS220+ 2 Bay Pentium NAS at around £250. Alongside this, you will need a smart Switch (to take advantage of LAG and 2GbE, 2x 10TB HDD at £230 each as you will not see any speed difference on a network connection with SSD (RAID 1). This will cost around just under £800. Alternatively, there have been other improvements in the base level ethernet connectivity in 2-4 Bay NAS solutions in the last few years, with 2.5GbE or even 5GbE available on the likes of the QNAP TS-x53D, TS-x73A or Asustor Lockerstor 2/4 series. These solutions arrive at only a fraction more and although they can possibly add another £100-200 to the price tag, this can be offset by time saved in the backup operations AND by purchasing a 4-Bay NAS over a 2-Bay and leveraging the price vs the redundancy vs the capacity (eg instead of 2x 10TB in RAID 1, purchasing 4x 3TB and getting better performance and an extra 2TB in RAID 5).

What do have to say about 1GBe

Over 1 Gigabit per second, in a perfect scenario – just over 20 hours. Realistically closer to 25 or 30 hours. SO the first few backups should be conducted over the weekend but all future ‘difference only’ backups should be fin at 12-hour intervals without harming the bandwidth too much, Likewise, you can scale this down as you utilize link aggregation (also known as port trunking, when ports are combined) and/or 2.5GbE/5GbE to reduce this figure down to 8 hours or just 4 hours respectively.

The Best Value 10GBe Network-Based Solution for 10TB of Data

In order to create the perfect cost-effective yet powerful 10GBe Network-based backup solution (so 10x faster than normal LAN) I would recommend the QNAP TS-431X3 with 10GBe  (at around £450) with SFP+ Connection and  SFP+ Cables with transceivers attached (Cable price dependant on length and transceivers). Additionally, you will need a 10GBe switch (at least £150 realistically), and for MAXIMUM speed 4x 4TB Seagate Ironwolf 125 SSD (at £450 per drive) in a RAID 5 which slows things a pinch but gives you the safety of 1 drive worth of redundancy. Of course, you can downgrade to Seagate Ironwolf 4TB Hard drives (at £85 per drive) and save over £1500, but you will see a noticeable dip in performance of around 200-400MB/s (NAS dependant). So the choice is yours. Lastly, you will need a 10GBe interface on the machine(s) you are backing up from in order to maintain the 10GBe throughput (or alternatively just have the NAS on a 10GbE connection and the clients all on 1GbE with bandwidth being shared as appropriate). In total this will cost around £2400+ for the SSD based solution and just £900-1000 for the HDD solution. None of this is set in stone, of course, you can scale things in a number of ways, using bigger NAS solutions (i.e. more bays) or using multiple 10GbE connections in LAG/Trunked connections.

What do have to say about 10GBe

The performance will largely be dictated by the distance of the backups, choice of HDD or SSD and types of files. However, over 10 Gigabit per second, in a perfect scenario – just over 2 hours. However this is a little optimistic and in practice, it will realistically weigh in closer to 3+ hours, as the complexity of the files (thousand so smaller emails and documents or fewer BIG media files, everyone is different). This of course is for the first few backups of a FULL 10 Terabytes of data. Later with incremental and ‘difference only’ backups, you will see times slashed heavily for the better.

The Cost of Thunderbolt 1, 2 or 3 Backup Solutions for 10TB of data

Fast becoming a connection of choice for photo and video editors in both the Mac and Windows community, Thunderbolt is the no-fuss connection that promises speed, without the technical nonsense. Much like before you can choose to go with SSD drives for supreme speed (at a hefty price tag) or HDD if you want to make economies. Below are the options best suited for a Thunderbolt 1 (although still legacy, still is in use), Thunderbolt 2 and Thunderbolt 3 Backups:

  • TB 1 DAS, 4-Bay, Cable, 4x 4TB SSD, RAID 5 enabled = £3000+ —- 2Hours + Backup time with SSD population / 3.5+ Hour for HDD Population
  • TB 2 DAS, 4-Bay, Cable, 4x 4TB SSD, RAID 5 enabled = £3500+ —-  1 Hour + Backup time with SSD population / 2-3+ Hour for HDD Population
  • TB 3 DAS, 4-Bay, Cable, 4x 4TB SSD, RAID 5 enabled = £4500+ —- 30-45min + Backup time with SSD population / 1.5 Hour for HDD Population

What do have to say about Thunderbolt 1, 2 and 3

CalcTool.orgThunderbolt does not lose speed over distance, however, most conventional cables you can buy max out around 5 metres and the ones included with the above enclosures arrive at 1-1.8m. In a real-world scenario you can realistically double this length of time listed above in the initial backups. However, it will MASSIVELY improve with subsequent backups. With the exception of a few, most Thunderbolt backups arrive with only Thunderbolt ports, so in order to maintain the speed levels of this backup, you need to either ensure that it is connected to your centralised depositary via Thunderbolt, or if it’s backing up multiple devices, that they are using a good networking device, as Thunderbolt Direct attached storage only allows a single connected device at any one time.

The Price, Speed & Suitability LTO-7, LTO-8 and LTO-9 Tape Backup 10TB Solutions

In the case of LTO / tapes, this kind of storage for 10TB can be incredibly inefficient for an extra layer of storage. You can purchase much smaller 1 and 2 tape frames/storage devices, but for what you are paying and the overall accessibility for all machines involved, it isn’t great. If you were regularly backing up 5x or 10x this amount of storage, it would be a different story. Internal operations can be upto 1000MB/s with compressed data and 400MB for raw uncompressed data. SO unless you are synchronizing between two LTO tape loading machines, you will almost certainly use uncompressed. However these are internal operations and as we are discussing backing up from existing systems to a storage device, we have to focus on the external connection. Most likely 10GBe network or 12GB/s SAS will be the means of backing up to your tape device. But Cost is hard to pin – easily £2000-3000 and upwards, over at least two tapes (capacity differed at each LTO generation) etc. Most likely around over  1-3 hours transfer time, but hugely impractical at this scale and most likely much higher in practice. Definite a good option for those at the enterprise tier, but anything less will be squandering their budgets significant with a weak ROI.

The Best Value USB 3.2 Gen 2 Backup Solution for 10TB of data

The latest available version of USB, also known as USB 3.1 Gen 2, is easily the cheapest way to store a 10TB backup at a very respectable 10 Gb/s (comparable to Thunderbolt 1) speed. You will need to ensure that the connected device(s) that you are backing up too/from use the newer USB 3.1 Gen 2 port to ensure you do not get bottlenecked at 5 Gb/s, but this Highpoint 6124V RAID 5 enabled USB 2 Gen 2 DAS enclosure arrives at £350+ and if populated with either 4x 4TB SSD or 4x HDD (same price difference as before), RAID 5 enabled = £2100+ for an SSD Based solution and just £700+ for a HDD based version

What do have to say about USB 3.1 Gen 2?

CalcTool.orgWith the best drives available you will have this 10TB localized backup over USB 3.1 Gen 2 finished in just over 2 hours. However taking system overheads into consideration, as well as the RAID 5 into account (something you could counter with a RAID 10 and 4x 6TB HDD perhaps) you are looking at between 2.5 and 3.5 hours completion. Additionally, a number of NAS Drive vendors have started implementing USB 3.2 Gen 2 in their systems, which means that a 10Gb/s USB DAS solution can be used as a means of creating a secondary backup by connecting it with your primary backup and running one of the many free backup/sync tools that NAS systems include with your purchase. Just remember that in order for this to be a truly safe 2nd tier backup, it cannot constantly reside in the same location as the primary backup.

Is Cloud Suitable as a 10TB Backup solution?

You may wonder why I have not suggested the cloud as a regular backup yet. It is certainly appealing. No parts are needed, just a healthy internet connection. You already have all the hardware you will need to establish this kind of synchronised backup – this should be by far the cheapest and easiest backup, right? Well yes and no. It IS cheap – in the short-term. Even if you take into account that your Business internet connection costs, from as little as £10 to £50 a month, reaching much higher once you consider fiber channelling, it is still pretty attractive. However you have to consider the time this backup will take and how it will affect the bandwidth throughout your business – otherwise, you will need to be conducted them overnight due to limit consumption. Some brands, such as Synology with their C2 platform, have rolled in an additional cloud service alongside their bare-metal solution. This is intended to be used as an alternative means of accessing an existing storage area that is synchronized with your NAS/local solution remotely (as well as benefiting from significantly easier remote access to data). NAS+Cloud can serve as a great 2-3/double backup option, as well as ensuring that your backups are in very different physical locations. Lastly, with intelligent caching and background synchronization between the NAS-THE CLOUD-CLIENT HARDWARE happening, a lot of the actual backing up can be hugely incremental and lessen the impact on the end-user, whether they are local to the NAS or remotely communicating with the C2 cloud (or 3rd party clouds such as Google Drive and Dropbox that are synced with the NAS). But what about the cloud on its own, not used in tandem with a NAS/Private server?

The first thing to factor in is the data being sent TO the cloud. Remember we are talking about Uploads, not downloads (downloads and a backup should only be considered during recovery, not day to day operations). Most internet services advertise incredible download speeds, but backups are almost exclusively upload based and upload speeds are normally a 10th or less than advertised download speeds. lastly, we can talk about costs. As although the initial costs are much less, let’s go for £50 a month for a dedicated high upload speed connection privately (closer to £500 for a business line) for your off-site backup. That is £600 a year. In 5 years, that is £3,000 (a cost that is the same or higher than most of the solutions discussed previously). The real kicker is that after those 5 years, you either have to continue paying to maintain this backup OR buy a suitable local storage drive to download it too – something you could have had ALREADY by going for the other solutions and thereby saving you thousands of pounds more.

I took the trouble of using the awesome tool at and if you have a 30Mbps upload speed (fairly respectable and the entry point outside of central city hubs). backing up 10TB initially would take  33 Days, 22 Hours, and 27 Minutes, 11 Seconds

That is horrendously long and you cannot just assume this is a one-off and negotiable with incremental backups and difference-only changes. You need a reliable and adaptive backup solution – not one that will do the job as long as you work within its limits. If you want to entertain the idea of a cloud-based backup of 10TB on a regular basis, we have to look into fiber and at least 2Gbps (so 2000 Megabits) to get to 12 hours for an overnight full backup (non-incremental). This is going to cost a small fortune and unless you intend to take advantage of this speed during the day-time, is a huge outlay for something that is not hugely accessible or reliable.

So, those are your options. Remember you are not limited to just ONE option and each of these solutions can be used in combinations, depending on your budget, physical environment, internet speeds or volume of client devices. In summary:

Price (more ★ = Higher Price) ★★★★★ ★★★★ ★★★★ ★★★★★ ★★★★★
Value (more ★ = more for your money) ★★★★★ ★★★★ ★★★★★ ★★★★ ★★★★
Scalability (more ★ = can grow more) ★★★★★ ★★★★★ ★★★★★ ★★★★★
Complexity (more ★ = more complex) ★★★★★ ★★★★
Speed (more ★ = faster) ★★★★★ ★★★★ ★★★★ ★★★★

How to Install TrueNAS Core on a QNAP NAS

How to Install TrueNAS Core on a QNAP NAS Drive – Step By Step Guide

Have you always wanted to test out or run your very own TrueNAS Core NAS setup, but are intimidated by the building of it? It’s understandable. As respected as the ZFS-powered server software is in the IT community, it is not really as user-friendly at the start as many of the Turn-Key solutions in the market from QNAP. So, what if you want to buy an already built server from QNAP (so, its been 100% built, has a manufacturers warranty and is designed for efficient and cool 24×7 use) BUT you also want to use the open-source (i.e free) TrueNAS Core software with abilities like ZFS architecture, app jails, fast build/rebuild, RAID resilvering, triple parity and near limitless scalability? Perhaps you have an older QNAP that is long out of warranty and you want to experiment? Well, good news for you! It is actually surprisingly easy to install TrueNAS Core on a QNAP NAS, takes around 15-20mins and is completely reversible (if done right)!

Note – a FULL 30 Minute Installation Guide for TrueNAS Core on a QNAP NAS is available HERE on the NASCompares YouTube Channel

Important – It’s important to note that TrueNAS Core is NOWHERE NEAR as user-friendly as QNAP QTS/QuTS and before making any switch to a new NAS OS, it is important that you understand the process, risks and differences in the platforms. I made a HUGE QNAP QTS vs TrueNAS Core comparison video HERE that you can use to see how each software compares before making any changes to your NAS. This guide is designed to help you use your QNAP NAS to run TrueNAS Core as it’s primary OS. If you go ahead with this and use the same HDD/SSDs in the system that you are currently using in the QNAP QTS/QuTS Setup, it will likely format them, so IF you want to reverse your QNAP NAS back to its QTS/QuTS set up with all your data/drives the same, you will need to remove them before using the TrueNAS setup, put them to one side safely and use new HDD/SSDs for your TrueNAS installation. Lastly, although this whole process is reversible, you are technically using the QNAP in a means that the brand does not state as ‘intended use’ and this MIGHT lead to support/warranty problems down the line if a fault appears in the QNAP or the software installation that was the result of the TrueNAS Core installation (the bios records everything!). This is HIGHLY UNLIKELY but not impossible (eg you work a TrueNAS Core server so hard and/or push the CPU to breaking point running particularly aggressive TrueNAS jails and/or use the inline compression/deduplication expensively in TrueNAS and it burns out the CPU – this would not be covered by your QNAP NAS support, as they did not certify that the system can handle this.

TrueNAS Core Software on QNAP NAS Hardware – What You Need?

It is worth highlighting that having just a QNAP NAS is not quite enough and in order to get TrueNAS Core up and running on a QNAP NAS requires a few extra checks and use of a few items you might have already in the home/office, or a quick $10 shop online at most. In order to upgrade your system to TrueNAS Core, you will need to consider/have the following:

  • A QNAP NAS Drive with (minimum) an Intel 64bit x86 CPU and a minimum 4GB of Memory (recommended 8GB+)
  • Download the latest stable release of TrueNAS Core here as a system image (you will be converting this to USB later on) – DOWNLOAD
  • Any Data that is currently on the QNAP NAS RAID that is mission critical to be backed up or moved (as it will be completely formatted)
  • A USB drive to use as the TrueNAS installation drive ( I recommend THIS ONE here from Sandisk, as it is low price and incredibly small, even at 32GB)


  • I recommend not using a USB larger than 32GB, due to the constraints of 1st party software to format larger than this in FAT32. Don’t be tempted to spend like $2 more for a 64GB, as the TrueNAS Core installation will occupy the full USB space (as you will create a system-image-USB) and space is utterly irrelevant when the TrueNAS Core installation is so small
  • A Disk Image to USB conversion too. I recommend ‘Rufus’, currently in ver 3.19 and can be run in a portable .exe form that doesn’t require installation – DOWNLOAD
  • A basic USB Keyboard (example HERE but really, any will do) and an HDMI Monitor (or simply any device that has an HDMI input – NOT output) such as a TV or Capture card
  • Hard Drive and/or SSD media (you should already have these, but just in case) for your storage Pool / RAID
  • Optional M.2 NVMe SSD of at least 120GB, but highly recommended – Installing TrueNAS Core is not unlike installing a Windows OS on a new PC, as you are connecting a USB to run the installer, but you need to target a drive in the QNAP NAS to install TrueNAS onto. Whichever drive you use, it will make that drive largely inaccessible for anything but the TrueNAS operating system. Therefore IF you are running a QNAP NAS that has internal m.2 NVMe SSD bays OR one with dedicated 2.5″ SSD bays, I highly recommend getting a low-capacity drive of between 60-120GB (these will be very cheap compared with larger HDDs that start in the Terabyte scales) and then use this for the TrueNAS software. This means that ALL of the main SATA storage bays of the QNAP are then used for your storage pool(s) (aka the RAID). Do NOT install TrueNAS on another USB drive during installation, as this is less stable.
  • OptionalDownload Advanced IP Scanner HERE, as it is a really useful tool for analyzing your network and finding your new TrueNAS Core NAS for remote access

That is about it. Most of these are devices are that you will almost certainly already have to hand.

Can I Reverse the TrueNAS Core Installation and go back to QNAP QTS?

Almost certainly YES! I say ‘almost certainly’, as there is one small caveat. When you make the change from QNAP QTS to TrueNAS Core on the NAS hardware, the drives (HDD and/or SSD) inside used in TrueNAS pools used in the new system software architecture. This works both ways if you want to revert back to QTS on the NAS too. You CANNOT use the Storage Pool, Volume structure, Folders etc of drives from a QNAP NAS in a TrueNAS setup (you will need to format these in TrueNAS). So, although the act of reinitializing the NAS to its original software is very easy (you just need to go into the BIOS of the QNAP using the same method in the guide below, then change the boot drive order BACK to the QNAP OS internal SSD), it will mean that any data that resides on the disks inside will be formatted. So, if you are choosing to make a change from one NAS OS to another, make sure you have your data appropriately backed up elsewhere OR move the drives that were in your QNAP (with their QTS/QuTS Storage structure) to one side safely and install new 3.5″ storage media for the TrueNAS pools etc. So, let’s begin the installation of TrueNAS Core on the QNAP NAS.

TrueNAS Core on a QNAP NAS – Step 1, Download TrueNAS Core

Head to the TrueNAS Core website HERE and download the latest stable release of the software to your local PC, Linux or Mac system. Make sure to remember where you downloaded it.

TrueNAS Core on a QNAP NAS – Step 2, Download Rufus USB Image Tool

Head to the Rufus website and download the latest version of that tool – I recommend downloading the standalone executable file here, as then it will immediately run when you double-click the file, without installation etc. It may redirect you to Github, but it will be the same executable file. Once again, remember where you downloaded it.

TrueNAS Core on a QNAP NAS – Step 3, Preparing the USB

Connect the small form factor USB Drive to your system (again, this is the one I used from Sandisk) and after a few seconds, it should appear as an available USB Drive. The drive MAY need formatting (you will be prompted to do so), if that is the case, then you can format it via the system prompts and by default, it will format it to FAT32 (as long as your USB is less than 32GB). If you are not presented with a system prompt to format your USB, then you can head into My PC, or My Computer via a windows computer and right-click the drive, select ‘format’ and format it that way.

If you have used the USB for other things previously, there is a chance that the drive has existing partitions in place. For that, the quickest way to completely remove any partitions is to open up the bottom-left windows system menu as normal, and then just type diskpart and open the command-line GUI tool. From there, use the command list disk to show the available drives that are connected, you will see your USB (normally disk 1 or 2, but can differ depending on your system layout and can be spotted by the storage amount). From there, type select disk # (where # is the drive number that your USB is shown as) and then type clean, which will then remove any index structure for the drive (i.e the partitions and existing format) and then you can go back to the My Computer/My PC page and format the drive to FAT 32 as normal.

TrueNAS Core on a QNAP NAS – Step 4, Creating a USB Installer Image of TrueNAS Core

Open the Rufus application and from there you will see the USB Drive (listed as NO NAME, or ‘UNTITLED’, ETC) at the top. From there, look to the select image/find image option (depending on the ver. of Rufus or your USB Image Creator tool of choice) and find the TrueNAS Core disk image you downloaded earlier). If the drive is not listed, it may have downloaded as a compressed/archive file. If that is the case, head to the location of where you downloaded TrueNAS Core (in your file explorer, not in Rufus) and right-click the file you downloaded. If the option to ‘extract‘ is visible, then you can extract it (i.e unpack it to the original form) in that same download directory. From there, head back into RUFUS and then the TrueNAS Core system image should be visible. Select it, then run the Rufus System image creator tool and create your USB bootable TrueNAS Core disk image.

REMEMBER! This will completely format your USB drive and any files that are on that USB will be destroyed. The system image creator tool will turn the USB into a pure boot image tool – the USB will not be usable for traditional storage again unless you completely format it again.

TrueNAS Core on a QNAP NAS – Step 5, REMOVE THE USB FROM YOUR PC!!!!!!!!!

Really, really important and sometimes overlooked. Once the USB creation is completed, you need to remove the USB (using the eject hardware safely option at the bottom right of your windows machine taskbar as normal). DO NOT accidentally leave the USB in your USB Ports for any longer than necessary. If you leave it in and your system reboots at any point (eg in a normal ‘end of day shut down, go home, reboot tomorrow’ scenario), then the system might boot directly into the TrueNAS Core installation and although it is easy to exit from, it can change your system default boot preferences, maybe even remove your primary boot drive as the OS drive – requiring a little messing with a windows installation disk to change it back. The odds of this are very small, but not zero, so make sure to safely remove your USB drive when the TrueNAS Core system image creator tool is completed.

TrueNAS Core on a QNAP NAS – Step 6, (OPTIONAL) – Install an NVMe SSD

This is an optional step, but one I would certainly recommend for newer-generation QNAP NAS devices. TrueNAS is a lot like a traditional computer operating system (eg Windows or macOS) in it’s architecture and will run at its best when the necessary boot files are located on a seperate, smaller and faster area of SSD/flash storage away from the general bulk storage. So, if possible/available in your QNAP NAS, I would recommend installing a smaller m.2 NVMe SSD drive and then using that as the target/location for your TrueNAS Core installation. This is not compulsory and you can also use a single HDD or SSD in one of the main storage bays of your QNAP, however, it means that this drive will unusable for general storage (i.e in any RAID configuration or storage pool). This CAN be negated with some creative portion creation, but I wouldn’t recommend it. Additionally, do NOT try to install TrueNAS Core on another USB drive that is connected to the system – this isn’t particularly stable and tends to result in a poorer TrueNAS Core experience. M.2 NVMe bays and their location in the QNAP NAS changes depending on the system. Some allow you to access these bays via the main HDD 3.5″ bays (eg the TS-464), whilst others (the majority) require you to remove the external chassis casing to access these bays (eg the TS-453E, TVS-872X, TS-873A, etc).

Reminder – TrueNAS is NOT a big program and you can use an SSD as small as 32GB and still have a tonne of provision for future storage space. However, M.2 NVMe SSDs are not available in smaller sizes than 120GB. Lower size than this and you will generally only find 2240 SSDs and/or SATA M.2 SSDs. These are still perfectly fine to use, but the performance difference between SATA and NVMe (PCIe) is HUGE! You can find many SSD options here on amazon for as little as $30  – Find Low Capacitiy and Low Price M.2 NVMe SSDs HERE on Amazon (already filtered the results)

NOTE – If you plan on upgrading the memory of your NAS to 4GB-8GB-16GB or higher (in order to use ALL of the features of TrueNAS Core to their fullest extent), I would recommend doing so at this point before rebuilding the physical chassis again, as many QNAP NAS have the 2nd SODIMM memory slot in really tight locations.

TrueNAS Core on a QNAP NAS – Step 7, Connecting the USB, Keyboard and HDMI Monitor

Next, we need to connect the external means to install TrueNAS Core on the QNAP NAS. Unlike when you set up your QNAP NAS for the first time, TrueNAS cannot typically be installed via the network like QTS. TrueNAS requires you to use a KVM (keyboard, Video Mouse – though you won’t need a mouse!) and go through the installation using a low-res graphical user interface. Now you will ONLY need this setup/items for the installation and initialization of your TrueNAS Core server and after that, you will be able to use the server over the network/internet as normal. You are going to need a basic USB Keyboard (not a Bluetooth or wireless one, as these may need drivers to run and you cannot install drivers at this point) and an HDMI Monitor/TV. You CAN use a mouse, but it is not hugely necessary and 99% of the choices in the setup of TrueNAS core can/will be via keyboard input. Also, I would also recommend connecting the NAS to the network during setup as this will allow the system to assume certain network values during setup that will save a tonne of time later. Once that is all connected, do NOT turn the NAS on yet – there is one small and slightly time-sensitive thing to do.

TrueNAS Core on a QNAP NAS – Step 8, Accessing the BIOS Menu of your QNAP NAS

Now that your QNAP NAS is all connected and you are ready at your keyboard/Monitor, turn the NAS on and wait till you hear a beep (should take between 5-15secs depending on the QNAP NAS). As soon as your hear that noise (and likely see a flashing character or underscore on the monitor screen), you need to continuously hit the F12 and/or DEL keys (not at the same time, just back and forth). One of these will result in the system displaying the blue BIOS menu (it changes between motherboards and QNAP uses a mixture of mobos in their Intel and AMD-powered systems). You need to be quick, as you only have about 3 seconds to do this before the QNAP will automatically boot from the small internal 5GB flash OS module that boots into QNAP.

TrueNAS Core on a QNAP NAS – Step 9, Booting from the New TrueNAS Installer USB

Next you need to tap ‘RIGHT‘ on the keyboard and head to the ‘Save & Exit’ option. At the bottom, you should see, under the ‘boot override‘ option, your USB Drive. Tap ‘DOWN‘ until you are highlighting the USB and then tap ‘Enter‘ or ‘Return‘ on your keyboard, as this will push the QNAP to boot from that USB and begin the TrueNAS Core installation. Later on I will show you how to force the system to ALWAYS boot into TrueNAS Core, but for now, we just need it to read from this USB this one time.

TrueNAS Core on a QNAP NAS – Step 10, Rebooting and Starting the TrueNAS Installer

This next step is a bit of a quick one. Around 5-15 seconds after you selected the USB Drive in BIOS, the screen will display the TrueNAS Installer option page. Tap ‘Enter’ as soon as you see it, as the page is on a countdown and when it reaches zero it will (possibly, depending on the version) reboot and then you will have to repeat the last few steps again!), So, in order to avoid this, tap ‘ENTER‘ as soon as this page appears.

After a few minutes, the TrueNAS Core GUI/Command will appear on your monitor and all you need to do is navigate the config choices to set up your TrueNAS Core NAS the first time.

Important – TrueNAS Core runs at its best when it is run on a separate drive from your storage. Much like an Operating System, you can install TrueNAS Core on an available SSD in a SATA or NVMe SSD slot in the QNAP NAS, then (after initialization) you can go into the TrueNAS Core > Storage area and create a pool of storage using the available storage media bays,

It is NOT recommended that you install it on a USB drive, for reasons of speed and power-connections.

After you have completed the setup and are back at the initial TrueNAS Core boot menu, select the ‘SHUTDOWN‘ option (not reboot/restart, for reasons I will explain in a moment).

TrueNAS Core on a QNAP NAS – Step 8, Remove the Boot USB Drive AND CHANGE BIOS!!!

Once your QNAP NAS has fully powered down, you need to disconnect the USB drive you installed earlier with TrueNAS Core boot loader on it. You need to do this otherwise, when you reboot the QNAP NAS, it can potentially reboot into the bootloader again. You can skip past this and/or it will not action a reinitialization without your input, but better to remove the USB and therefore allow the system to always immediately boot into the TrueNAS Core system you just created.

Next, you need to head back into the BIOS from earlier. Keep the Keyboard and HDMI Monitor connected and use the same method you used earlier during the initial boot of the QNAP (pressing F12 and/or Delete repeatedly when you hear the first QNAP beep after about 10-15 secs) and as soon as you are greeted with the familiar blue BIOS screen. From here, tap right a few times to highlight the ‘Boot’ option and change the option for Boot Priority #1. The default is QNAP OS, you need to change it to the drive you installed TrueNAS on (whether that is a SATA/NVMe SSD or one of the main storage bays).

This will change the boot order to allow the system when it is first powered on to always boot into TrueNAS. After this, you can click right again in the BIOS menu to select the option to Save and restart. The system will then boot into the TrueNAS initialization (first time setup).

TrueNAS Core on a QNAP NAS – Step 9, Reboot the NAS

Upon rebooting the QNAP into TrueNAS Core (can take up to 5 mins, but usually much quicker). You have two options with how to access the configuration and controls. You can use the HDMI+Keyboard if you choose for console/command level access. Alternatively (much more recommended), use a program such as Advanced IP Scanner, which is free and VERY useful anyway, or even network command prompt) to scan your local area network and find where the QNAP with TrueNAS Core is located (i.e it’s IP). This IP (eg is what you put into the URL bar ofay web browser and it will load into the login GUI for TrueNAS Core. From here you will need to use the username ‘root’ in combination with the password that you created during initialization.

And that is about it. You now have TrueNAS Core installed as the default OS of your QNAP NAS. From here you can do anything and everything that his highly regarded ZFS powered server software offers. Head into the Storage area and start creating pools, as well as areas for caching and lots more features.

TrueNAS was recently updated to ver.13 in a stable release of the FreeBSD format, as well as new improvements in the Linux-based version ‘TrueNAS Scale’. The first thing you are going to need to do when setting up your TrueNAS Core > QNAP NAS server is set up your storage. Do this by heading into the storage tab and following the handy steps on screen. After that, you can pretty much do anything on your new ZFS NAS!

EXTRA – How to Reverse Your QNAP NAS from TrueNAS Core to QNAP QTS / QuTS Software Again

Now, it is worth remembering that switching your QNAP NAS to run TrueNAS Core instead of QTS/QuTS is not a one-way street and you can reverse this relatively easily. Do remember first though that:

  • Any data on the HDD/SSDs inside the QNAP that were used in TrueNAS Core server setup will not be accessible/usable with the QNAP NAS system and will likely be flashed/formatted during the QNAP QTS reinitialization
  • You will need your Keyboard and HDMI Monitor again in order to get back into BIOS
  • If you kept your original QNAP RAID Pool on HDDs etc to one side (i.e you removed the already configured storage media in their RAID from the QNAP when you changed to TrueNAS and put these drives safely to one side), you should be able to migrate this data back into the QNAP NAS during re-initialization with ease. That said, YOU SHOULD ALWAYS HAVE A BACKUP FOR THIS DATA REGARDLESS

In order to reverse the QNAP NAS from TrueNAS Core back to QNAP QTS/QuTS Software, you need to (from a cold boot) access the BIOS menu again (so, at boot, with your Keyboard and monitor connected, press the DEL and/or F12 key over and over when the QNAP beeps, like before) and when you reach the BIOS menu, tap RIGHT until you reach the ‘Boot page. Then change the ‘Boot Option #1’ option from the TrueNAS installation drive back to the QNAP OS (internal flash 5GB module). Once that is done, head into the ‘Save & Exit‘ and then select ‘Save Changes and Restart‘. Doing this will restart the QNAP NAS and it will automatically boot into the QNAP QTS/QuTS boot sequence. From here your NAS will either automatically boot into the QNAP Setup page OR (if you have your original QNAP NAS RAID drives, with their Pools, Volumes, etc) it will just boot into the QNAP NAS software as normal.

Alternatives to Drobo from Synology or QNAP – Which NAS Should You Buy?

27 juillet 2022 à 01:33

Leaving Drobo NAS and Buying a Synology or QNAP – Get it Right, First Time

For a long time, I championed the Drobo Brand of network attached storage (NAS) as a great option for users looking to have their very own no-fuss, easy to set up and content-creator-friendly system. However, I think it would be fair to say that in the last 5-6 years, whilst many of the more ambitious NAS brands such as QNAP and Synology were pushing the boundaries of what people can do with their NAS systems in software and hardware, Drobo had made little or no innovation in their either department. Indeed, although we saw the impressive and surprisingly affordable Thunderbolt RAID device, the Drobo 5D3, in the world of NAS we really saw things start to stagnate. Fast forward to 2022, and we recently found out that Drobo (and its parent company StorCentric) had sadly filed for Chapter 11 bankruptcy, citing impacts on their business from the pandemic. Although the company has stated in several interviews that they intend to carry on later, with a smaller product line perhaps, I think the brand had been in trouble long before the pandemic and for a while, many users on the brink of buying their latest NAS or were in the process of upgrading an existing Drobo populated network storage environment, started considering making the switch to the bigger and more established NAS brands, Synology and QNAP. These two brands have 22 and 18 years of experience respectively in network attached storage and in that time have continued to release new and exciting innovations that challenge alot of the rather unexciting and rudimentary storage services that Drobo NAS systems arrive with.

What Do Synology and QNAP Provide that Drobo Doesn’t?

NAS has a technology that anyone (home or business) can buy has been around for around two decades now and in that time, ALOT has changed. The days of a NAS being just a simple blob of storage (1+ HDDs) that are connected to the network/internet and accessible remotely are long gone. Now modern NAS systems arrive with a full range of tailored applications (i.e. interfaces that allow you to access file types such as Photos, Music, Video, Docs, etc in a manner better suited to their output), a full graphical user interface accessible via your web browser that is more akin to a complete operating system, many client tools and apps, huge variety of business tools and all of this whilst still providing configurable storage to you, your family or your business. Below is just a handful of the thing that a Synology or QNAP NAS can do, that a Drobo either cannot do or does in a very limited capacity:

  • Bigger Range of solutions in 1, 2, 4, 5, 6, 8, 12-Bay and bigger desktop NAS solutions
  • Many, many Mobile Applications
  • Incredibly user-friendly GUIs via the web browser (DSM and QTS) that give NAS devices an operating system comparable to Windows or MacOS
  • AI-Powered Photo Recognition
  • Huge variety of NAS Apps
  • Highly configurable and customizable iSCSI and Remote Targetted storage tools and Protocols supported
  • Multi-tiered and comprehensive backup tools covering NAS-to-NAS, USB, Cloud and VM Backups
  • Wide Variety of Desktop/Client Apps
  • Diverse RAID configurations and Storage Expansion Options
  • 10GbE by Default or as an Optional Extra
  • A large number of security tools and configuration tools (starting with
  • NVMe SSD Bays for caching and/or storage
  • Dedicated Premium Surveillance, Virtual Machine, Multimedia, Containers and Cloud Sync Software
  • Fully featured Plex and Emby Media Server Support
  • SaaS Sync Tools (Active Backup on Synology and BoXafe on QNAP)
  • A large variety of email hosting, web hosting and database creation tools
  • Not just supporting EXT4, but also supporting ZFS or BTRFS’ file systems

Now, it is worth remembering that Drobo DID release some innovations over the years in their NAS and DAS systems. They were the first to introduce a much more innovative LED system on the front of their system’s to denote system storage use, particular activity and more detailed warning patterns. They were one of the first to integrate m.2 SSD caching upgrade bays into their desktop systems (though using mSATA or M.2 NVMe), and they were one of the first to introduce internal battery systems in their desktop NAS that allowed the system to safely close read/write activities in the event of the system suffering a critical power failure. Then of course there was BeyondRAID, their flexible RAID configuration that allowed easy RAID expansions and mixed drive use. These innovations were all good, it’s just a shame that they all came around many years ago and the brand has not moved forward in hardware or software technology since.

Why Choose Synology NAS to Replace Your Drobo?

Synology is often considered the ‘Software Choice’, as DSM (Diskstation Manager) is by far the most user-friendly, secure, responsive and ‘OS-like’ platform available in the whole of NAS. It may seem one of the most expensive, but with it, you get some genuine boundary-breaking software with your purchase.  You still get a great level of hardware in the majority of Synology NAS solutions, but the real draw of Synology is that software. Not only does it support your own hardware environment of PCs, Macs, entertainment devices and mobiles in their own respective software, but DSM also includes MANY applications designed around keeping all your data IN-HOUSE. So, replace Skype/Whatsapp with Synology Chat, Replace Google Docs and Office365 with Synology Office. Use Synology Drive to make your storage visible and accessible the way YOU want it, and export your entire cloud/data network over to a Synology NAS and remove all the external access as and when you need! They aren’t the cheapest and they want you to do it ‘there way’, but it’s a pretty decent way. Additionally, their recent DSM 7.0 software has left many users impressed, with enhanced support of those 3rd party cloud storage and business services, AI photo recognition, their surveillance platform continuing to win awards and even an in-house cloud service in Synology C2. Stylizing themselves very much as the ‘Apple’ of this industry, they really do focus on keeping things straightforward and intuitive.

PROS of Synology NAS

  • Easily the most intuitive and Usage browser-based GUI (award-winning DSM 6.2/7.0/7.1) – FULL Review HERE
  • One of the best Surveillance NAS software solutions
  • Most popular vendor for Mac users for it’s UI
  • Incredibly feature-rich NVR software included, in Surveillance Station
  • Includes Active Backup Suite – Enterprise level and fully featured Backup Co-ordination software
  • Lowest Power Consumption vs other brands
  • A large # of their systems arrive with m.2 NVMe SSD caching upgrade bays
  • Quiet chassis compared with other brands
  • Task specialised Ranges like ‘PLAY’, ‘PLUS’ and ‘J’ make buying easier
  • The best range of first-party software, with Synology Office, Chat, Mail, Drive and more
  • SHR and SHR-2 – also BTRFS available in most solutions
  • Cloud Services and Hybrid Storage Tools available in Synology C2
  • Desktop and Rack-mount options are available
  • Best software for Home and SMB

CONS of Synology NAS

  • Often the most expensive
  • Recent Enterprise NAS Hardware has changed Compatibility in favour of Synology HDDs and SSDs
  • Generally, Synology NAS has the lowest hardware power in their systems
  • NVMe SSD Bays are for caching ONLY, they cannot be used for super-fast storage pools
  • More technically minded folk will need to dig a little to get to the nitty-gritty
  • SHR is not available on Enterprise NAS Systems
  • Network ONLY – no HDMI, Audio in/out, Thunderbolt, etc

Why Choose QNAP NAS to Replace Your Drobo?

Often considered the choice for the more hardware-aware buyer, if you are looking for a much more traditionally computer associated hardware – QNAP NAS is certainly the one that springs to mind. Generally considered the ‘innovators’ of the NAS industry, they have the largest range of solutions available Notwithstanding the fact that their hardware is by FAR the most evolved platform in NAS (thunderbolt 3, multiple HDMI, 10Gbe standard solutions, Silent NAS, AI solutions and advanced SSD caching), the platform is fantastically diverse, providing great NAS options alongside network switches, network adapters and generally reshaping your hardware environment for the better. The software has also evolved dramatically into its own beast, moving away from trying to imitate and carving its own path. It is a little more technically (and I really do mean a little) but it is far more rewarding for it. They do not feature some popular items on their portfolio, such as BTRFS or a fluid RAID system like SHR/BeyondRAID, but make up for this with their own range of alternatives and in most cases succeed. Get your reading glasses on though, as their range is quite vast and might overwhelm you a tad. In recent years the brand has shifted focus a great deal more towards software in efforts to meet the gap with their rival Synology to pretty good success. This is often achieved by releasing software that does the previously impossible before anyone else, but lacking a little of the polish of their biggest rival. Recent achievements with HybridMount, vJBOD, HyperVisor Protector, QuMagie and Multimedia Console have been received remarkably well, arriving onto the scene 1-2 years before anyone else. Alongside this, QNAP still has easily the best virtual machine and backup software for home and SMB in Virtualization Station and Hybrid Backup Sync.

Recommended Synology Replacement for the Drobo 5N2 NAS – The DS920+ and DS1522+ NAS

Choosing to replace the Drobo 5N2 5-Bay NAS with a Synology is actually a surprisingly easy choice. Right now at the time of writing, there are two very clear Diskstaiton devices that you can choose (if you want to stay at this kind of storage sale). The Synology DS920+ 4-Bay NAS (originally released in 2020) and the Synology DS1522+ 5-Bay NAS (released in June 2022). The former has been in the market for long enough that multiple deals are available and if/when the DS923+ arrives on the scene, it will likely become increasingly affordable – in spite of this, the hardware inside is great and it’s a solid fully featured NAS. The latter choice, the DS1522+, is the latest 2022 generation release from the brand, has great default system hardware and plenty of scalabilities and upgrade options to add to the system’s utility in years to come. Find out more about them both below:

Synology DS920+ 4-Bay NAS $500+

Intel Celeron 4-Core J4125, 4/8GB Memory, 1GbE, NVMe SSD Caching, Expandable, SHR, 4x SATA Bays, 3yr Warranty

The DS920+ NAS is something that Synology should be proud of. It is a great entry into their already impressive range of Diskstation NAS devices. If you are looking for a brand new NAS to consolidate your home media, to support your relative as the ‘IT whizz’ of the family, or move your business away from Google Drives and DropBox’ onto something safer, more scalable and dependable – then the DS920+ has alot to offer you. It gives you a great base to start using the DSM platform, as well as a good means to upgrade your storage internally at a later date (expansions in memory, expansions in storage, expansion in NVMe). If you are an existing DS918+ or DS916+ owner, this might not seem like the jump you were waiting for. There are always areas of improvement, the USB ports, the 1Gbe, that 1 memory slot – but these are things that Synology no doubt feel should be pushed into a higher price/hardware bracket – Allowing the DS920+ Price to be as close to its predecessors it can be. Whether you agree or disagree, I think that we can agree that this NAS is still giving you alot of bang for your buck in 2020. Thank you once again to ‘Takeo from Tokyo‘ for all his assistance on this hardware review

What we said on 29/06/22

The Synology DS1522+ is a good NAS drive and most business-focused users are going to appreciate what this newer configuration of hardware is able to provide. There was never any doubt in the extent to which this new NAS would support DSM7, and given its architecture, there is virtually nothing in the popular NAS software that this system cannot do. Likewise, having the option of 10GbE on a Diskstation of this scale will be hugely attractive to some, though the proprietary means with which you need to upgrade is arguably less desirable. The R1600 CPU is a good choice of processor for file handling and simultaneous tasks, as is the 8GB of memory that this system arrives with, plus the potential to ramp it up to 32GB. After that though, the desirability of this system to home users and multimedia users is a little less compelling and with such a large audience of users who look at NAS for their media streaming, the DS1522+ not featuring a more graphically enabled chip will leave them somewhat underwhelmed. Bottom line, the DS1522+ is a solid and full DSM7 supporting system here and you cannot fault the design, internal/external performance and ease of use of this Synology NAS. However, there will always be users wondering why this NAS never arrived with an Intel chip.

Recommended QNAP Replacement for the Drobo 5N2 NAS – The QNAP TS-464 and TS-h973ax

If you decide to move away from the Drobo 5-Bay 5N22 and towards a QNAP, then I recommend opting for either the 2022 generation TS-464 NAS (as it is really is the best hardware vs scale vs price point the brand has ever released) or the incredibly mutli-facited QNAP TS-h973ax, which as 10GbE, 3 kinds of storage media supported across 9-Bays and the choice of file system at initialization of ZFS or EXT4. Here is more information on these two NAS and what we said about them when reviewed:

QNAP TS-464 4-Bay NAS $599+

Intel Celeron 4-Core N5105, 4/16GB Memory, 2×2.5GbE, NVMe SSD Caching or for Storage, HDMI 2.0 4K 60PFS, USB 3.2 Gen 2 (10Gb), USB RAID Expandable, PCIe Gen 3×2 Upgrade Slot, 4x SATA Bays, 3yr Warranty

The TS-464 comfortably arrives with the best hardware in its tier of the NAS market and that is something that QNAP has always been quite good at. Even if you rewind just 5 years, the level of hardware scalability and ease of upgradability that the TS-464 provides is frankly incredible and, fast forward to 2022, is still pretty unmatched. A Desktop 4-Bay NAS (eg Prosumer RAID 5 storage) has always been the next confident step for users who are tired of their hands being tied by subscription cloud services from Google, OneDrive and DropBox, who are looking for their own competent, flexible and fully-featured private server. In the TS-464 NAS, you find a system that is unquestionable the best hardware for your money you can possibly get right now. In software, things are a little less straightforward. QTS 5, although massively software and service-rich, arrives as a complete operating system in your web browser with multiple mobile/desktop clients and hundreds of applications and apps that can be installed at the touch of a button – which can all too often be something of a steep learning curve for many. Lacking the chewable, user-friendly nature of many of their rivals, QNAP and its software/service still have a tendency to be a bit of an information overload that can quickly intimidate the novice. However, for those that are looking for a system that is completely customizable in how/when/where you want data presented to you, as well as a wide degree of 3rd party support, QNAP and QTS 5 still manages to provide a huge degree of brand-unique service that are simply not available elsewhere. Just be prepared to invest your time wisely in its setup and more time ensuring the system is perfect for your needs.

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 straight forward 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!

Recommended Synology Replacement for the Drobo B810n NAS – The DS1821+ NAS

Replacing or deciding against the Drobo B810n 8-Bay NAS system and opting for a Synology is, if anything, considerably easier than moving away from the 5N. Synology has a great history of 8-Bay NAS devices and the 2021 generation DS1821+ is a fantastic choice of NAS system. It supports the full range of DSM applications, has scalable storage, can be expanded by ten more drives, has in-built m.2 NVMe slots, a high bandwidth PCIe Upgrade slot and still manages to be very petite. Here is more information on the Synology DS1821+ and what we thought of it at review:

Synology DS1821+ 8-Bay NAS $1,100+

AMD Ryzen V1500B Quad Core, 4/32GB Memory, 4x1GbE, 8x SATA HDD, 2x NVMe SSD for Caching, PCIe Gen 3×8 Upgrade Slot, SHR or Traditional RAID, BTRFS or EXT4 File System Choice, 3yr Warranty

What we said on 15/12/20

What you have here is a solid piece of hardware that very much lives up to everything Synology promises, even if some of those promises aren’t to everyone’s taste. With a hardware architecture that we have already tested to notable success in the DS1621+ previously, we already knew that this NAS would be able to do everything it promised. Many users looking to spend their annual business budgets on an improved or extended data storage solution will find the balanced position of hardware vs software found by the Synology DS1821+ to be quite desirable, as well as the scaled potential to upgrade external performance via PCIe and storage via eSATA. However, there is no ignoring that despite the fact this 2020 release excels in many things, it also arrives with a little bottlenecking in a number of others. The continued default utilisation of 1Gbe on the newest generation by Synology is somewhat perplexing and although I have continued admiration for Synology’s engagement with intelligent M2 NVMe cache utilisation and providing a solution that allows more flexible upgrade paths, I know that there are still users who just wish they could use that super fast NAND for raw storage pools and have better than gigabit connections out by default. It has never been a secret that buying a Synology NAS solution was always a largely ‘software over hardware’ purchase, and the DS1821+ is still a fine example of that balance. However, with other brands closing the gap in what they can offer the SMB (Small/Medium Business) user, while still providing superior hardware and similar warranty coverage, there is the tiniest feeling that the DS1821+ is a NAS that sits on its laurels a bit. Hugely upgradable and still with that award-winning and fantastically intuative DSM software, the DS1821+ is about buying a solution you can adapt within its lifespan and not one that will knock your socks off on day one. A solid and dependable data storage solution, if a little safe, at the end of 2020.

Recommended QNAP Replacement for the Drobo B810n NAS – The TVS-872X NAS

Unlike the previous QNAP suggestions I have made when moving away from a Drobo, when it comes to choosing a QNAP alternative to the Drobo B810n, I would currently recommend the 2020 released TVS-872X (a modified version of the also still available Thunderbolt 3 NAS, the TVS-872XT). Although this NAS has been around a while (and likely due an upgrade to a new version very soon), the QNAP TVS-872X is a 10GbE equipped 8 bay, with NVMe SSD slots, two very high bandwidth PCIe slots, USB 3.2 Gen 2, 4K HDMI, optional ZFS or EXT4 and after all of that – it has an Intel Core i3 or i5 Highly powerful CPU than can also be accompanied by up to 64GB of DDR4 memory. This is a beast of a system that arrives with a surprisingly modest price point when compared to most other NAS of the same scale or hardware – and the fact it is a little older means that the price is improved further in many shops. Again, QNAP are very likely to release a newer, more powerful and ultimately more expensive version of this product family soon, but it is STILL a great NAS that holds it’s own in 2022. Here is what we thought of it at the review:

QNAP TVS-872X 8-Bay NAS $1,999+

Intel Core 8th Gen i3/i5 4/6-Core CPU, 8-64GB DDR4 Memory, 1x 10GbE, 2x1GbE, NVMe SSD Caching or for Storage, HDMI 2.0 4K 60PFS, USB 3.2 Gen 2 (10Gb), USB RAID Expandable, 2x PCIe Gen ([email protected] 3×16 and [email protected] 3×4) Upgrade Slot, 8x SATA Bays, Audio In/Out, 3yr Warranty

What we said on 24/05/21

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.

Why Not Use Cloud Services like Google Drive, OneDrive or Dropbox instead of a NAS?

Do not think that 3rd party cloud services are bad, they really aren’t! In fact, you should always consider adding a 2nd or 3rd tier into your backup strategy at home/work, and synchronization of files/folders on your NAS with the cloud is a good means to ensure you have another backup in place. Additionally, most NAS feature a variety of 256bit encryption options, password protection, 2 step verification and more to allow secure access is ensured to the NAS and the content, even via the cloud. Additionally, bg NAS brands like Synology and QNAP have been supporting Hybrid Cloud services that not only allow cloud storage to be bolted onto your NAS storage for shared usage and access, but also both brand support backup and synchronization with cloud collaborate services, such as Google’s G Suite and Microsoft’s Office 365. So there is DEFINITELY still a valid and useful place for 3rd party cloud services in 2022, however, I rarely advocate the use of these cloud services as a PRIMARY storage location. They ARE convenient and you can get a limited amount of space included for free, but I generally have three core reasons that I do not recommend cloud as a first-tier storage.


COST – The cost of most 2-year subscriptions costs about the same as if you just purchased even a small-scale NAS on day 1. It might seem like just 5 or 10 bucks a month, but over 2 or 3 years, it all adds up and moreover, after that time you either need to keep on paying every month or still buy a NAS or DAS system for the data to live on. Might as well buy the NAS sooner rather than later as it will be inevitable eventually.

ACCESS – NAS provides more apps, file-level tailored use and can be better adapted into popular 3rd Party applications like PLEX, KODI, APPLE TIME MACHINE and DLNA supported devices. A cloud provider severely limits the kind of access you have on a regular basis.

PRIVACY – NAS provides full individual user control and access, as well as admin controls. Plus the NAS can be fully disconnected from the Internet/Network at your discretion. A cloud provider has a relative pre-set safety protocol that, when cracked on one or two occasions, opens up mass hacking

This is not to say that data on your NAS is completely inaccessible. Any NAS brand can only really stay 1 step ahead of the hackers, patching exploits as they are found (no different than any online service really), but a NAS is a means to create a secure, customizable and ultimately bespoke data storage solution.


What About Moving from Drobo to Asustor or Terramaster NAS?

Obviously, as NAS is such a popular and highly evolved area of the tech industry (despite it still also remaining quite niche compared with traditional computers and laptops), Synology and QNAP are not the ONLY brands in the market! Indeed, if you have been looking at moving away from Drobo and saw some affordably devices from Asustor or Terramaster, you will likely wonder why I have not covered them as much in this article (though I DO cover them and their solutions in the video embedded in this article above). Although both brands have been providing some great hardware (both for the price AND just generally) in 2022, these brands do not provide the full range of software and services (especially 1st party developed) that QNAP and Synology do. Their respective software in ADM and TOS aren’t bad, indeed they are very good and very responsive with many apps, they just are not on the same level as Synology DSM and QNAP QTS/QuTS right now. You can find out more about their software in the software review videos of each below:


Should I Move From Drobo to TrueNAS Core?

Many Drobo users, after using their systems for many years and (after becoming increasingly proficient) started to feel its limitations, might have heard about the free and DiY NAS server platform ‘TrueNAS’ (aka FreeNAS) and considering making the switch towards it after Drobo. It will come as absolutely no surprise to anyone that when it comes to TrueNAS is a fantastically capable software for managing your storage. It even manages to swerve the downfall of being ‘too enterprise’ but arriving as an open source free software platform to be enjoyed by businesses and storage enthusiasts. There is no avoiding that it IS quite a technical mountainous learning curve if you are arriving at it from a position of zero storage or network experience, but the last few big TrueNAS system updates have gone a long way to update some UI elements to be more intuitive, software wide help notes available at all times and the community support is as on-point at it has ever been. If you are a home users looking for a hurdles setup or a day-1 deployable system for your small business, then TrueNAS may be too big a jump for you and you would be better off with a traditional off-the-shelf NAS system. However, if you have the know-how, you have the willingness to get your hands dirty and already have the hardware in mind/in-house, then TrueNAS stands in a class of it’s own and thanks to some very unique architecture choices that are almost utterly unique to this platform, it’s pretty unparalleled in its scope. Just please, PLEASE remember that a Drobo NAS is a ‘turnkey’ solution (aka, ready to go out of the box) and TrueNAS Core and TrueNAS Scale involve ALOT more setup and a much higher learning curve. You can buy TrueNAS-ready systems, such as the iXsystems series of devices, but these are still rather expensive compared with the modest Drobo and still require ALOT of tech knowledge to make the most of. You can find out more about the TrueNAS software platform in my written and video review below:
