NAS & Storage Servers price comparison UK
NAS devices occupy a peculiar corner of the storage market: they look deceptively simple — a box with some drives — yet the gap between a £150 entry-level unit and a £100,000+ enterprise rack server is enormous. Our catalogue spans 389 products, from the Synology BeeStation (a plug-and-play solution that barely needs configuring) to HPE rack systems that wouldn't look out of place in a data centre. Understanding where you sit on that spectrum is the first decision to make.
QNAP dominates sheer volume here with 179 listed models, averaging around 524 £ across the full range — though that figure is skewed heavily by enterprise units. Synology, with 93 products, punches well above its weight on software quality: DiskStation Manager (DSM) remains the gold standard for NAS operating systems, and it's the main reason home users and SMBs consistently choose Synology over rivals. QNAP's QTS is more feature-rich for power users who want virtualisation, container support, and granular network configuration. Neither is wrong — they're just different philosophies.
Prices start from 132 £ for a bare-bones single-bay desktop unit, with the sweet spot for home and small-office buyers sitting below 271 £. That bracket covers solid 2- to 4-bay NAS units from Synology, QNAP, and the increasingly competitive Asustor range. Step up to the 400 £ range and you're into 8-bay rackmount territory or high-performance desktop units with 10GbE connectivity and NVMe cache slots — genuinely useful for video editing workflows or multi-user SMB environments. Beyond 527 £, you're firmly in enterprise territory: HPE, NETGEAR ReadyNAS, and QNAP's QuTS hero ZFS-based systems built for virtualisation, iSCSI block storage, and failover clustering.
One thing worth flagging: most NAS units ship without hard drives. The price you see is for the enclosure and processor only. Budget separately for internal hard drives — NAS-rated drives from WD Red or Seagate IronPro are strongly recommended over desktop drives. If you're building a proper backup strategy, pairing your NAS with a dedicated backup storage device for offsite redundancy is worth considering. For environments needing shared block-level storage across multiple servers, a disk array may be a more appropriate solution than a NAS altogether.
Retailers like Amazon.co.uk, Scan, and Insight UK tend to offer the most competitive pricing on QNAP and Synology units. John Lewis occasionally stocks entry-level Synology models with their standard two-year guarantee, which is worth factoring in if after-sales support matters to you. Black Friday and January sales can yield meaningful discounts on mid-range units — it's one of the few tech categories where waiting a few weeks genuinely pays off.
How to Choose a NAS or Storage Server
Most buyers get tripped up by the same mistake: choosing a NAS based on bay count alone, then discovering the processor can't handle simultaneous transcoding, RAID rebuilds, and a Docker container without grinding to a halt. The CPU is the real bottleneck — and it's the spec that's hardest to upgrade later. Here's what actually matters, in order of importance.
Processor: the spec that defines your ceiling
The CPU determines everything from transcoding performance to how many users can connect simultaneously without slowdown. Entry-level NAS units use ARM-based chips (Realtek RTD1619B) or Intel Celeron J/N-series — fine for basic file sharing and media streaming at home, but they'll struggle with on-the-fly 4K transcoding or running multiple Docker containers. If you plan to use Plex or Jellyfin with hardware transcoding, look for an Intel Celeron J4125 or better. For SMB environments with 10+ users, Ryzen Embedded R1600 or Intel Xeon D processors offer a meaningful step up. QNAP's QuTS hero ZFS-based systems require even more headroom — don't pair them with underpowered CPUs.
Bay count and RAID strategy
Two bays is the minimum for any meaningful redundancy — RAID 1 mirrors your data across both drives, so a single drive failure doesn't cost you everything. Four bays open up RAID 5 (one drive can fail) and RAID 10 (better performance, two drives can fail in the right configuration). For home use, a 2- or 4-bay unit covers most scenarios. SMBs should think in terms of 6–8 bays minimum to allow for capacity growth without rebuilding the array. One practical note: Synology's Hybrid RAID (SHR) is genuinely clever for mixed drive sizes — you don't need to buy identical drives to build a redundant array, which saves money over time.
Connectivity: 1GbE vs 10GbE
Standard Gigabit Ethernet (1GbE) tops out at roughly 115 MB/s in real-world conditions — adequate for streaming video or backing up a few workstations, but it becomes a bottleneck the moment you're doing large file transfers regularly. If you're editing video directly from the NAS or running a busy SMB share for 5+ users, 10GbE is worth the premium. Many mid-range QNAP and Synology units now include at least one 2.5GbE port as a compromise. Check your switch compatibility too — a 10GbE NAS connected to a 1GbE switch gains nothing.
Form factor: desktop, tower, or rack?
Desktop and tower units sit on a desk or shelf — they're quieter, cheaper, and perfectly suited to home offices and small businesses. Rack units (1U, 2U, 3U) mount in a standard 19-inch server rack and are designed for data centres or server rooms where space efficiency and cable management matter. Don't buy a rack unit for a home setup unless you already own a rack — they're louder, less energy-efficient at low loads, and the form factor adds cost without benefit. Conversely, a desktop NAS in a server room is an operational headache.
NVMe cache slots
Many mid-range and premium NAS units include M.2 slots for NVMe SSDs used as read/write cache. This can dramatically improve random I/O performance — particularly useful if your workload involves lots of small file access (databases, virtual machines, busy shared folders). For pure media streaming or sequential backup workloads, NVMe cache adds little. It's a feature worth paying for if you're running a busy office NAS, but don't let it drive your decision if your use case is straightforward.
Software ecosystem and longevity
Synology's DSM is widely regarded as the most polished NAS OS — intuitive, well-documented, and backed by a large community. QNAP's QTS/QuTS hero is more powerful but has a steeper learning curve and a patchier security track record (several high-profile ransomware incidents targeted QNAP devices specifically). Asustor's ADM is a credible third option at lower price points. Whichever you choose, check the manufacturer's software support timeline — Synology in particular is known for long-term DSM updates on older hardware, which matters when you're investing in a device you expect to run for 5–7 years.
- Entry-level home NAS (From 132 £ to 271 £) : This bracket covers 1- to 4-bay desktop units from Synology (DS124, DS223J, DS224+), QNAP (TS-462), Buffalo, and Asustor. Processors are ARM or entry Celeron — capable of file sharing, basic media streaming, and Time Machine backups, but not 4K transcoding. Ideal for home users, students, or small offices with modest needs. Don't expect to run virtual machines or heavy Docker workloads here.
- The sweet spot for SMBs and enthusiasts (From 271 £ to 400 £) : Where the market gets interesting. You'll find 4- to 8-bay units with Ryzen Embedded or Intel Celeron N5095 processors, 10GbE options, and NVMe cache slots. Synology DS723+, QNAP TS-432X, and QNAP TS-464eU live here. This is the right range for small businesses, home labs, video editors, and anyone running Plex with transcoding. Asustor offers strong value competition in the lower half of this bracket.
- High-performance and rackmount (From 400 £ to 527 £) : Rackmount units dominate here — Synology RS422+, RS2423RP+, QNAP TS-864EU-RP. Expect 8–24 bays, redundant power supplies, 10GbE as standard, and processors capable of handling virtualisation and iSCSI. Suited to growing SMBs, creative agencies with shared storage needs, or IT teams consolidating infrastructure. NETGEAR ReadyNAS units also appear at this level.
- Enterprise and data centre (Over 527 £) : HPE ProLiant storage servers, QNAP QuTS hero ZFS systems, and high-density NETGEAR units. These are purpose-built for enterprise workloads: ZFS deduplication, failover clustering, 25/40GbE connectivity, and petabyte-scale capacity. HPE averages significantly above the category mean — you're paying for enterprise support contracts and hardware reliability guarantees. Not for the faint-hearted or the budget-conscious.
Top products
- Synology DiskStation DS224+ NAS/storage server Desktop Intel® Celeron® J4125 2 GB DDR4 0 TB Black (Synology) : The most-compared unit in this category for good reason — the J4125 CPU handles hardware transcoding and Docker containers without breaking a sweat. The go-to recommendation for home users stepping up from basic file sharing. Two bays limits long-term capacity, but for most households that's not a constraint.
- Synology BeeStation NAS Desktop RTD1619B 1 GB 4 TB SSD Black (Synology) : The only unit in the top 15 that ships with storage included — 4TB built-in, no drive shopping required. Genuinely plug-and-play, aimed squarely at users who find traditional NAS setup intimidating. The ARM processor and 1GB RAM mean it's not for power users, and you can't expand storage the way you can with a bay-based NAS. But as a first NAS, it's hard to fault.
- Synology DiskStation DS723+ NAS/storage server Tower Ryzen Embedded R1600 2 GB DDR4 DiskStation Manager Black (Synology) : The Ryzen Embedded R1600 makes this a genuinely capable unit for enthusiasts and small offices — faster than any Celeron-based NAS at this form factor. Two bays feels restrictive at this price point, but the M.2 NVMe cache slots and 10GbE expansion option give it real longevity. Best suited to users who prioritise performance over raw capacity.
- QNAP TS-462-4G NAS/storage server Tower Intel® Celeron® N4505 4 GB DDR4 0 TB QNAP QTS White (QNAP) : Four bays at an accessible price with 4GB RAM out of the box — a better starting configuration than many Synology equivalents at this level. QTS is more complex than DSM, so factor in a learning curve. Solid choice for home lab users or small offices comfortable with a bit of configuration. The white finish is unusual and divides opinion.
- Synology RackStation RS2423RP+ NAS/storage server Rack (2U) Ryzen Embedded V1780B 8 GB DDR4 0 TB DiskStation Manager Black, Grey (Synology) : The most capable SMB-grade unit in the top 15 — 12 bays, redundant PSU, Ryzen Embedded V1780B, and 8GB DDR4. Designed for businesses that need reliable shared storage without enterprise-level complexity. Expensive, but the redundant power supply alone justifies the premium in a production environment. Overkill for home use; exactly right for a 10–50 person office.

Frequently Asked Questions
Do NAS units come with hard drives included?
The vast majority of NAS units sold in this category are diskless — the price covers the enclosure, processor, RAM, and OS only. You'll need to purchase hard drives separately. Budget for NAS-rated drives (WD Red Plus, Seagate IronWolf) rather than desktop drives; they're designed for 24/7 operation and vibration tolerance in multi-drive enclosures. A few models like the Synology BeeStation are the exception, shipping with built-in storage.
What's the real difference between Synology and QNAP?
Synology prioritises ease of use and software polish; QNAP prioritises hardware features and flexibility. DSM (Synology's OS) is more intuitive and has a better app ecosystem for typical home and SMB tasks — photo management, cloud sync, backup. QNAP's QTS offers more granular control, better virtualisation support, and more exotic connectivity options, but it has a steeper learning curve. If you're not a power user, Synology is the safer choice. If you want to run VMs, containers, and custom network configurations, QNAP rewards the effort.
Is RAID the same as a backup?
No — and confusing the two is one of the most dangerous mistakes NAS owners make. RAID protects against hardware failure (a drive dying), but it offers zero protection against accidental deletion, ransomware, or fire and theft. A proper backup strategy follows the 3-2-1 rule: three copies of your data, on two different media types, with one stored offsite. Your NAS is the primary storage; a separate backup device or cloud service is the backup.
How many bays do I actually need for a home setup?
For most home users, two bays is the practical minimum — it allows RAID 1 mirroring for basic redundancy. Four bays give you more flexibility: RAID 5 for better capacity efficiency, or the option to expand storage without rebuilding the array. Unless you're storing a very large media library (10TB+) or running a home lab, a 4-bay unit will serve you for years. Six or more bays is overkill for personal use.
Can I use any hard drive in a NAS, or do I need specific drives?
Technically you can use any SATA drive, but we strongly advise against desktop drives in a NAS. Desktop drives aren't rated for continuous operation and can trigger RAID errors due to their error recovery behaviour (TLER/ERC). NAS-rated drives — WD Red, Seagate IronWolf, Toshiba N300 — are tuned for 24/7 use, vibration resistance, and NAS-compatible error recovery. Most manufacturers publish compatibility lists; always check your specific NAS model before buying drives.
What should I watch out for when buying a cheap NAS?
The main pitfall with budget NAS units is buying underpowered hardware that becomes frustrating within a year. ARM-based processors with 1GB RAM are fine for basic file sharing, but the moment you add Plex, a download manager, and a backup job running simultaneously, performance collapses. Also watch for models with no expansion slots (no M.2, no PCIe) — you're locked into the hardware as-is. Buffalo units in particular are very affordable but offer limited software support and no upgrade path. Buy for where your needs will be in three years, not where they are today.
Is a NAS worth it in 2026 when cloud storage is so cheap?
Yes — for most users who store more than a few terabytes, a NAS pays for itself within 2–3 years compared to equivalent cloud storage subscriptions. More importantly, a NAS gives you full control over your data, no monthly fees, and local network speeds that cloud storage can't match for large file access. The two aren't mutually exclusive: many NAS units sync to cloud services (Backblaze B2, Amazon S3) as an offsite backup layer, giving you the best of both worlds.
