📊 As of 29 August 2026, the typical NAS on Amazon.co.uk is £160/TB or £0.16/GB across the 3,460 live listings we track, with the widest choice of drives priced around £44.1/TB or £0.044/GB. The best deals on Amazon.co.uk start from about £285 for 8TB (£35.7/TB), £322 for 14TB (£23/TB) and £614 for 20TB (£30.7/TB). The current best value is 14TB at roughly £23 per TB.

Tempted by RAID 0 because it promises more speed? Let me be the friend who explains the catch before you regret it.

RAID 0 stripes your data across multiple drives for more speed and combined capacity. Sounds great.

But it adds zero protection. If any one drive in the stripe dies, every byte across the whole array is gone. Not damaged. Gone.

The table above shows the live price per TB on your marketplace, because whatever you build, the drives are the cost, and your data deserves better than RAID 0.

What RAID 0 actually does

Let me explain the trade plainly.

RAID 0 splits your files into pieces and spreads them across two or more drives. Because the drives work in parallel, reads and writes can be faster, and you get the combined capacity of all the drives.

That is the upside: speed and a big single volume.

The downside is brutal. There is no redundancy at all. Each file is scattered across every drive, so losing any one drive means losing all of it.

Why the risk is so serious

This is the part people underestimate.

With a single drive, you have one thing that can fail. With two drives in RAID 0, you have two things that can fail, and either one takes down everything.

So RAID 0 does not just fail to protect you. It actively makes total data loss more likely than a single drive would. Add more drives to the stripe and the risk climbs further.

You are trading a meaningful jump in failure risk for some extra speed. For most people that is a bad deal.

When RAID 0 is actually fine

To be fair, it has a few legitimate uses.

The key word is disposable. If everything on the array can be regenerated or lives safely elsewhere, the risk does not matter and the speed is a nice bonus.

What most people should do instead

Here is the better path for almost everyone.

Check the live prices above, buy good drives, and put them in a setup that protects your data rather than gambling it.

The bottom line

RAID 0 is rarely worth it. It buys speed and combined capacity, but it removes all protection and makes total data loss more likely, since any single drive failing wipes the whole array.

Use it only for disposable scratch data. For everything else, a fast NVMe for speed or a redundant array for safety is the smarter move. Buy your drives from the live prices above and keep your data on something that will not betray you at the first drive failur.
