Rarely, for most people. RAID 0 stripes data across drives for more speed and combined capacity, but it adds zero redundancy. If any single drive fails, you lose everything on the whole array. The speed gain is usually not worth doubling your failure risk.

Does RAID 0 increase the risk of data loss?

Yes, significantly. With two drives in RAID 0, either one failing destroys all the data, so you are roughly twice as likely to suffer total loss as with a single drive. More drives in the stripe means even higher risk.

When is RAID 0 actually useful?

For temporary scratch space or workloads that need raw speed and hold nothing you cannot lose, like a video editing cache you can rebuild. Even then, modern NVMe SSDs are often fast enough alone, making RAID 0 unnecessary for most.

📊 As of 28 September 2026, the typical NAS on Amazon.co.uk is £153/TB or £0.153/GB across the 3,350 live listings we track, with the widest choice of drives priced around £61.6/TB or £0.062/GB. The best deals on Amazon.co.uk start from about £299 for 8TB (£37.4/TB), £367 for 14TB (£26.2/TB) and £612 for 20TB (£30.6/TB). The current best value is 14TB at roughly £26.2 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.

Temporary scratch space that holds nothing precious, like a video editing cache you can rebuild from the originals.
Workloads that genuinely need raw sequential speed and where the data is disposable.

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.

Want speed? A single modern NVMe SSD is blisteringly fast on its own, no RAID needed.
Want safety with multiple drives? Use a redundant level like RAID 1, RAIDZ1 or RAIDZ2 so a drive can fail harmlessly.
Want both capacity and safety? Redundant RAID plus a backup, never RAID 0.

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.
