Synology DS224+ 2 Bay NAS Desktop Review UK (2026) - The Honest Verdict

The Synology DS224+ 2 Bay NAS Desktop is not a router. Not a mesh node. Not a range extender. If you landed here expecting Wi-Fi coverage advice, the category tag has led you astray, and that's worth sorting out immediately. What this actually is: a two-bay Network Attached Storage device, a small desktop box that sits on your desk or in a cupboard and gives you a proper place to keep all your data, back things up, and share files across every device in your home or office without relying on a cloud subscription you'll be paying for forever.

The frustration this solves is real and specific. You've got files scattered across three laptops, a phone, a work machine, and maybe an old external drive that makes a worrying clicking noise. You're paying for Google One or iCloud storage that you don't fully trust. You want to back up your photos somewhere you actually own. Or maybe you've got a small business and you're done with the chaos of everyone saving things to their own machines with no central copy. The DS224+ is Synology's answer to all of that, and with 882 owner reviews averaging ★★★★½ (4.5), it's clearly landing well with the people buying it. The question is whether it's the right tool for your particular problem.

This review is grounded in the verified product specifications, the feature set Synology publishes, and the consistent patterns that emerge from owner feedback. We haven't set one up in a rack, and we're not going to pretend otherwise. What we can tell you is what the spec supports, where owners consistently praise it, where they don't, and whether the money makes sense.

The four core features Synology highlights for this unit are centralised data storage, sharing and syncing across systems, backup and restoration tools, and built-in data management. Those aren't marketing fluff in this case. They describe the actual software suite, called DiskStation Manager (DSM), that runs on the box. DSM is genuinely one of the better NAS operating systems available at this price point, and it's a big part of why Synology commands a premium over bare-bones competitors.

The unit ships without drives, which is standard for NAS enclosures. You buy the drives separately, which gives you flexibility but also means the total cost is higher than the box price alone. Maximum raw storage depends entirely on what drives you install, but two-bay units at this level are typically paired with drives up to 16TB or 20TB each, giving you up to 40TB raw or around 16TB to 20TB in a mirrored RAID configuration for data redundancy. Synology maintains a compatibility list of tested drives, so check it before you buy.

For home users, the practical reality is that once the DS224+ is set up on your network, every device in the house can see it. You map a network drive on your Windows PC, you add it as a location in Finder on a Mac, and your photos app on your phone can back up automatically over Wi-Fi. The "access from anywhere" part works through Synology's QuickConnect service, which routes external access without you having to mess around with port forwarding on your router. Owners who travel for work mention this as one of the more useful real-world features, being able to pull files from home without a VPN headache.

The limitation of a two-bay unit is not really about software coverage. It's about physical capacity and redundancy options. With only two bays, your choices are RAID 0 (all storage, no redundancy, risky), RAID 1 (mirrored, half the raw capacity, one drive can fail and you're fine), or just using both drives as separate volumes. If you need more than two drives for capacity or want the protection of RAID 5 across three or more drives, you're looking at a four-bay unit like the DS423+. For most home users and small offices with modest storage needs, two bays is genuinely enough.

Owners who connect the DS224+ directly to a Gigabit switch or router via Ethernet report smooth, fast file transfers, with large video files moving quickly enough to stream 4K content from the NAS to a local device without buffering. The Intel Celeron J4125 processor is capable enough to handle transcoding for Plex or Synology's own Video Station at 1080p, though 4K hardware transcoding is where things get more nuanced and depends on the specific media format. Owners running multiple simultaneous tasks, like a backup job running in the background while someone else is accessing files, report that the DS224+ handles it without grinding to a halt, which is more than you can say for the ARM-based alternatives at lower price points.

Where speed drops are consistently reported is over Wi-Fi rather than wired connections. This is not a DS224+ problem specifically. It's physics. If you're copying large files from a laptop connected over 2.4GHz Wi-Fi to a NAS, the bottleneck is your wireless connection, not the NAS. Owners who've wired their main machines directly to the network, or who have a solid Wi-Fi 6 setup, report much better sustained throughput. The practical takeaway: if you're buying this for media serving or large file transfers, think about your network infrastructure at the same time.

But RAID is not a backup. This is the single most important thing to understand before buying any NAS. RAID 1 protects you against a drive failure. It does not protect you against accidental deletion, ransomware, a flood, or the NAS itself dying. Synology knows this and has built out a proper backup ecosystem around DSM. Hyper Backup lets you back up your NAS data to an external USB drive, another Synology NAS, or a cloud service like Backblaze B2 or Amazon S3. The 3-2-1 backup rule (three copies, two different media, one offsite) is genuinely achievable with this setup, and owners who've gone through the process of setting up Hyper Backup report that it's straightforward once you understand what you're doing.

Active Backup for Business is another tool. It's a free package available through Synology's Package Centre that lets you back up PCs, Macs, and even virtual machines to the NAS. For a small business or a home user who wants proper device backups rather than just file storage, this is genuinely useful and the kind of feature you'd pay a subscription for with a cloud service. The fact that it runs locally on hardware you own is the whole point.

For home use, the practical device capacity question is less about raw numbers and more about what you're running simultaneously. Streaming a movie to one device while another is doing a backup job while a third is syncing files is the kind of concurrent load the DS224+ handles fine according to owner reports. Where it starts to show limits is in more demanding scenarios: running a busy Plex server with multiple simultaneous transcodes, or running a Docker container alongside surveillance streams alongside active file transfers. The two-bay form factor and the 2GB base RAM are the constraints here. You can expand the RAM, which helps, but if you're planning to run the DS224+ as a mini-server with a lot of active services, you'll hit the ceiling faster than you would on a four-bay plus unit with more headroom.

For the target buyer, which is a home user or small business wanting reliable centralised storage, sharing, and backups, the device capacity is more than adequate. Owners running it as a Plex server for a household, a shared drive for a small team, and a backup destination for several machines simultaneously report no meaningful issues. The problems start when people try to use it as a full home server running a dozen Docker containers. At that point, you've outgrown the platform.

The future-proofing question for a NAS is really about software support rather than hardware standards. Synology has a solid track record of supporting its plus-series hardware with DSM updates for many years. DSM 7, the current major version, brought significant improvements to the backup tools, the photo management app, and the overall interface. Owners of older Synology units report still receiving updates years after purchase, which is a meaningful differentiator from cheaper NAS alternatives that get abandoned quickly. The DS224+ is current hardware running current software, so you're not buying into a dead end.

The SATA drive standard it uses is mature and stable. Drives are widely available, prices continue to fall for high-capacity options, and there's no imminent risk of the format being obsoleted in a way that would strand your investment. If you're comparing this to cloud storage on a five-year horizon, the economics of owning your own hardware and drives start to look very favourable once you account for the ongoing subscription costs of cloud alternatives. That's a genuine argument for NAS ownership that the DS224+ makes well.

Synology Drive is the one that most directly competes with cloud services. It gives you a self-hosted file sync and sharing platform that works similarly to Dropbox or Google Drive but with your own storage. You can share files with external users via links, sync specific folders across multiple machines, and access everything through a web browser or mobile app. For a small business that wants to stop paying for cloud storage subscriptions, this is a compelling argument. Owners who've migrated from Google Drive or Dropbox to Synology Drive report a period of adjustment but generally land on it being worth the switch.

The video surveillance capability via Surveillance Station is worth a specific mention because it's a feature that catches people off guard. If you have IP cameras at home or in a small office, the DS224+ can act as your NVR (Network Video Recorder), storing footage locally on the NAS drives rather than in someone else's cloud. Two camera licences are included free. This alone can justify the purchase for some buyers who are currently paying a monthly fee for cloud camera storage. The practical limit is drive space and the number of cameras you want to run, but for a small setup it works properly according to owners who use it this way.

The DSM interface itself is browser-based, which means you manage the NAS from any computer on your network by going to a web address, no separate app required for the core management. The mobile apps (DS File, DS Photo, Synology Drive) are available on both iOS and Android and are generally well-rated on their respective app stores. Owners report them as reliable rather than brilliant. They do what they need to do without drama, which is honestly the right outcome for utility software.

The setup process involves installing drives, powering on, and visiting a web address to run the installation wizard. Synology has made this genuinely approachable for non-technical users. The wizard walks you through drive configuration, RAID selection, and basic network setup in a way that doesn't assume you know what you're doing. Owners who describe themselves as non-technical report getting the basic setup working within an hour or two. The more advanced features, like configuring Hyper Backup to an offsite destination or setting up Surveillance Station, take more time to learn but the documentation is solid.

Once powered on, you visit find.synology.com from a browser on the same network, and it finds the device automatically. The installation wizard then guides you through the process of installing DSM, formatting the drives, and setting up your first user account. This is where Synology's investment in user experience shows. The wizard is clear, the choices are explained in plain English, and you're not dropped into a command line at any point unless you want to be. Owners who've set up NAS devices from other brands often comment on how much smoother the Synology process is.

Ongoing management is done through the DSM web interface, which looks and behaves like a desktop operating system in a browser. There's a taskbar, icons for different applications, a file manager, a control panel. It's a bit quirky if you've never seen it before, but most owners find it intuitive within a day or two of use. Package installation is handled through the Package Centre, which works like an app store. You find what you want, click install, and it handles the rest. Updates for both DSM and installed packages are flagged in the interface and applied with a click.

There are USB ports on the DS224+, which serve a specific and useful purpose: connecting external drives for additional backup destinations or for importing data. You can plug in a USB drive and use DSM to copy data to or from it, which is handy for the initial data migration from an existing external drive or for keeping a local backup copy on a USB drive that you then take offsite. The USB ports are not for connecting peripherals in the traditional sense. They're data ports for drive connectivity.

The unit connects to your existing router or switch via Ethernet cable, which is not included but is a standard cable you'll have lying around or can pick up cheaply. There's no Wi-Fi built in, which is the right call for a NAS. You want a wired, stable connection for something that's storing your data and running backup jobs. Relying on Wi-Fi for a NAS introduces unnecessary instability. Owners who've tried to use powerline adapters or MoCA adapters to get a wired-ish connection to a difficult location report mixed results, and the recommendation is always to run a proper Ethernet cable if you can.

The DS423+ is the four-bay version of the same family. It costs more, obviously, but it gives you two additional drive bays which means more total storage capacity, RAID 5 as an option (which gives you redundancy with less wasted capacity than RAID 1), and more room to grow. If you think you'll need more than two drives within a couple of years, it's whether the DS423+ is the smarter long-term buy even at the higher upfront cost. Migrating from a two-bay to a four-bay NAS later is possible but involves buying new hardware, so thinking ahead saves money over time.

The other comparison worth making is against cloud storage services. At the DS224+'s price point, plus the cost of two drives, you're making a meaningful upfront investment. But if you're currently paying for multiple cloud subscriptions, the maths often works out in the NAS's favour within two to three years. You own the hardware, you own the data, and your ongoing costs are electricity rather than monthly fees. Owners who've done this calculation and switched from cloud to NAS are generally satisfied with the decision, particularly those who had privacy concerns about storing sensitive data on third-party servers.

Who should buy this: home users who want to stop paying cloud storage subscriptions and take ownership of their own data. Small businesses with a handful of employees who need shared file storage, device backups, and basic collaboration tools without the ongoing cost of cloud services. Anyone with a growing photo or video archive who wants a proper home for it. People running IP cameras who want to store footage locally. If any of those descriptions fit, the DS224+ is a solid choice.

Who should skip it: anyone who needs more than two drive bays now or will soon. If you've got a lot of data or want RAID 5 protection, go straight to the DS423+ and save yourself the hassle of upgrading later. Also, if you're not willing to invest a couple of hours in setup and learning the software, a NAS is not for you regardless of which brand you choose. And if your storage needs are modest and you're happy with cloud storage, the economics don't necessarily favour buying a NAS at all.

The honest don't-overspend line: if you're on a tighter budget and don't need the x86 processor for transcoding or Docker containers, the QNAP TS-233 does the basics at a lower price. You lose some software polish and the Synology ecosystem, but for pure file storage and simple backups, it works. The DS224+ earns its premium if you want the full Synology experience and plan to use the more advanced features. If you just want somewhere to dump files, there are cheaper ways to get there.

Editorial score: 8.5 out of 10. Excellent software, solid hardware, strong long-term support. Loses half a point for the Gigabit-only LAN in a world where 2.5GbE is becoming standard, and another point for the two-bay ceiling that some buyers will outgrow faster than they expect. But for the target use case, it's the right tool.
