The best Budget NAS in the UK is the TerraMaster F2-425, around £223.99 at last check. It pairs a genuine Intel x86 quad-core chip with 2.5GbE and hardware transcoding at a price that undercuts most 2-bay Intel rivals, including Synology's ageing Celeron boxes. The 4GB RAM is soldered-adjacent modest but sufficient for file serving, backups and Plex on standard-definition to 1080p content. Against ARM-based budget units like the QNAP TS-233 or UGREEN DH2300, it simply does more per pound, which is what a budget pick should do.
Best budget NAS by tier
Three sensible stopping points depending on how much you want to spend.
Which should you pick
Choose the QNAP TS-233 if
- You only need basic file storage and backup, nothing media-heavy
- Your network is still 1GbE and you're not planning to upgrade soon
- Budget is the only factor and you can live with a modest ARM chip
- You want the absolute cheapest entry into a proper NAS OS
Choose the TerraMaster F2-425 if
- You want Plex or Jellyfin transcoding without a struggle
- You have (or plan) a 2.5GbE network and want to use it
- You'd rather spend a little more now than regret an ARM chip later
- You want genuine x86 flexibility for future software or containers
Why Intel beats ARM at this price point
The gap between the cheapest ARM NAS boxes and the cheapest genuine Intel ones has narrowed to almost nothing this year, which changes the maths for anyone shopping on price alone. The QNAP TS-233 and UGREEN DH2300 both use ARM chips with no hardware transcoding, fine for pure storage but limiting if you ever want to stream media to a phone or smart TV without stuttering. The TerraMaster F2-425, by contrast, costs only slightly more than these ARM units and brings an Intel x86 quad-core with proper hardware transcode support and 2.5GbE as standard.
That's the single biggest lesson for budget NAS shopping in 2026: spending an extra £20 to £30 to jump from ARM to Intel buys you a machine that will still be useful in three years, rather than one you'll want to replace the moment you try to do anything beyond basic file storage. RAM matters less at this tier since none of these budget boxes ship with enough to make heavy use of caching or virtual machines, so don't let RAM capacity alone sway a decision between two otherwise similar boxes.
Where Synology used to dominate the budget space, its current 2-bay models like the DS223 and DS224+ carry a real price premium for the DSM software experience but no hardware transcode on current DSM anyway, which removes one of the traditional reasons to pay more. For pure value, the Intel-powered TerraMaster and UGREEN boxes now offer more hardware capability for less outlay, provided you're comfortable with a less polished but perfectly functional operating system.
A word of caution on 1-bay and single-drive units
Several of the cheapest options on this list, including 1-bay models, offer no redundancy at all. A single drive failure means total data loss unless you're backing up elsewhere. Budget NAS shopping should never mean skipping RAID entirely if the data matters to you; a 2-bay unit in RAID 1 is the sensible minimum for anything you can't afford to lose.

Frequently asked questions
What's the cheapest NAS worth buying in 2026?
The QNAP TS-233 at around £199 at last check is the cheapest sensible option, though its ARM chip and 1GbE port mean it's best suited to simple backup and file storage rather than media streaming.
Is it worth paying more for an Intel-based budget NAS?
Yes, generally. The TerraMaster F2-425 costs only a little more than ARM rivals like the QNAP TS-233 but adds hardware transcoding and 2.5GbE, both of which matter the moment you want to stream media or move large files quickly.
Do budget NAS boxes support Plex transcoding?
Only the Intel-based ones do. ARM models such as the QNAP TS-233 and UGREEN DH2300 have no hardware transcode support, so they'll struggle with anything that needs on-the-fly format conversion.
Should I avoid Synology for a budget build?
Not necessarily, but be aware that current Synology models like the DS223 and DS224+ don't offer hardware transcoding either, despite costing more than comparable Intel-based TerraMaster or UGREEN units. You're paying for DSM software polish, not extra hardware capability.
How much RAM do I actually need for a budget NAS?
For file storage and backup, 2GB to 4GB is enough. If you want to run Plex, a handful of containers, or anything beyond basic file serving, look for a model that allows a RAM upgrade rather than one with soldered memory.
Is a 1-bay NAS ever a good budget choice?
Only if you have a separate backup plan. A single drive with no RAID means one failure wipes your data, so most people are better served by a 2-bay unit running RAID 1, even at a slightly higher price.
