Best NAS for Home Lab and Small Business in 2026
If your external drives have multiplied past the point of sanity, a network-attached storage box is the fix. A NAS gives you one place to back up every device on your network, stream media to a TV, run Docker containers, and keep working files accessible without depending on a laptop that's asleep in a bag somewhere.
We looked at three NAS units that cover the range most home lab builders and small businesses actually need: a genuinely affordable 2-bay for first-timers, a 4-bay with the networking and NVMe headroom to do real work, and a 5-bay built for teams that need redundancy and room to grow. None of these are the cheapest boxes on the market, and that’s deliberate — the ultra-budget models tend to cut corners on RAM or CPU in ways that make themselves felt within a year.
- Three current NAS picks, ranked by who they actually suit
- A side-by-side spec comparison
- What separates a NAS worth buying from one you'll outgrow in six months
- Answers to the questions people ask most before buying
The short version
- Best budget pick The Synology DS224+ is the sensible starting point for home backups and light media serving — two bays, DSM’s excellent software, no drama.
- Best overall The QNAP TS-464-8G earns its higher price with 2.5GbE networking, dual NVMe slots for caching, and enough CPU to actually run containers or light virtualisation.
- Best for growing teams The Synology DS1525+ is the one to buy if you need real redundancy — five bays, ECC RAM, and room to expand to fifteen drives without replacing the unit.
- Don't skimp on RAM Whatever you buy, more RAM matters more than a faster CPU if you plan to run virtual machines, surveillance software, or multiple Docker containers.
Our Top Picks at a Glance
Best Budget: Synology DS224+
The DS224+ is where most people should start, and there's no shame in that. It pairs an Intel Celeron J4125 with 2GB of RAM (expandable to 6GB), which sounds modest until you remember that its job is backup and file sharing, not video transcoding at scale. Where it earns its price is DSM — Synology's operating system — which remains the most approachable storage software available. Setting up automated backups from a laptop, syncing photos off a phone, or sharing a folder with a family member takes minutes, not a weekend of forum-reading.
Two bays means no redundancy beyond RAID 1 mirroring, and there's no 2.5GbE port, so transfers are capped at standard gigabit speeds. For a first NAS handling backups and the occasional movie stream, that's rarely a bottleneck. It becomes one the moment you start editing large video files directly off the NAS or running anything resembling a home lab workload — at that point, look at the TS-464 instead.
Current price: £437.69 inc VAT at Ballicom (correct at time of publication — always confirm live pricing before buying).
Best Overall: QNAP TS-464-8G
This is the one we'd actually buy. The TS-464-8G steps up to an Intel quad-core processor and ships with 8GB of RAM, which is enough headroom to run QNAP's container station, a Plex server, and ordinary file sharing at the same time without the box grinding to a halt. The two M.2 NVMe slots are the standout feature — they're not for bulk storage, they're for read/write caching, and on a NAS handling lots of small random reads (a busy Plex library, a team's working files) the difference is noticeable within the first week.
Dual 2.5GbE ports mean you can either double your bandwidth with link aggregation or keep one port for normal traffic and dedicate the other to backups, which is exactly the kind of flexibility a home lab setup benefits from. Four bays gives you real RAID options — RAID 5 or 6 if you want redundancy without sacrificing too much capacity. It's not cheap, but per-feature it's the best value of the three.

Best for Growing Teams: Synology DS1525+
The DS1525+ is a different category of purchase. Five bays, an AMD Ryzen V1500B quad-core CPU, and 8GB of ECC RAM (expandable to 32GB) put it firmly in small-business territory rather than home lab enthusiast gear. ECC memory is the detail worth paying attention to: it catches and corrects memory errors before they get written to disk, which matters a great deal once a NAS is holding invoices, client files or anything else you genuinely cannot afford to lose or silently corrupt.
It also scales. Synology sells expansion units that take this NAS from five bays to fifteen, so a business that starts with five drives of headroom doesn't have to migrate everything to a new box in two years — it just adds an expansion unit and keeps going. Dual 2.5GbE ports and two NVMe slots carry over from the same generation as the TS-464, so caching and networking performance are similarly strong.
This replaces our earlier pick, the DS1522+, which Synology has discontinued — worth knowing if you see it listed cheaper secondhand, since it's no longer sold new and support will taper off first.
Current price: £1,116.98 inc VAT at Ballicom (correct at time of publication — always confirm live pricing before buying).

How to choose a NAS
RAM is what determines whether a NAS can comfortably run multiple services at once, and it’s usually the cheaper thing to upgrade later — if the model allows it at all.
Two bays is fine for pure backup. Four or more gives you real RAID redundancy without giving up too much usable capacity, and room to grow into.
Standard gigabit Ethernet caps real-world transfers around 110MB/s, which becomes a bottleneck fast once you’re moving large files or backing up multiple machines at once.
Error-correcting memory catches silent data corruption before it’s written to disk. For personal media storage this is a nice-to-have; for anything a business depends on, it’s close to essential.
Common questions about buying a NAS
Do I need to buy hard drives separately?
Yes, almost always. All three NAS units above are sold as diskless enclosures — you add your own drives, typically NAS-rated models like Seagate IronWolf or WD Red, which are built for the always-on, vibration-heavy environment inside a multi-bay unit rather than desktop drives.
Is a 2-bay NAS worth it, or should I go straight to 4 bays?
If you’re backing up two or three devices and streaming the odd film, a 2-bay unit like the DS224+ is genuinely enough. Go to 4 bays if you expect to add drives over time, want RAID redundancy beyond simple mirroring, or plan to run anything beyond basic file sharing.
Can I run Plex or other media servers on these?
Yes, all three support Plex or the manufacturer’s own media server app. The Celeron in the DS224+ handles direct-play fine but struggles with heavy transcoding; the QNAP and the higher-end Synology have enough CPU headroom to transcode multiple streams without stuttering.
What's the actual difference between RAID levels on a NAS?
RAID 1 (mirroring, used on 2-bay units) copies data across two drives so one can fail without data loss, at the cost of half your total capacity. RAID 5 and 6 (used on 4+ bay units) spread data and parity information across more drives, giving you better capacity efficiency while still surviving one or two drive failures.
Do these NAS units work for a small business, or do I need something more expensive?
For a small business, the DS1525+ is a genuinely solid choice — ECC memory, expandable capacity, and Synology’s business-grade DSM features like Active Backup for Business. Larger organisations with heavier workloads will outgrow it, but for a small team it covers most needs without stepping up to rack-mounted enterprise storage.
Which NAS should you actually buy?
- Match the NAS to your actual workload, not the spec sheet
- RAM and networking speed matter more day-to-day than raw CPU power
- Buy more bays than you think you need — you will fill them
- ECC memory is worth the premium for business-critical data
Buy based on what you’re actually doing with it, not on which box has the most bays. If this is your first NAS and its job is backups and basic file sharing, the DS224+ will do everything you need without wasting money on capability you won’t use. If you want a NAS that can also run containers, cache reads with NVMe, and push real network speed, the QNAP TS-464-8G is worth the jump. And if you’re storing anything a business genuinely can’t afford to lose, the extra cost of the DS1525+ and its ECC memory is cheap insurance.
