4 × 22 TB in RAID 0

Usable space and the risk of striping for 4 drives of 22 TB each.

4 × 22 TB drives in RAID 0 give 88 TB of usable space, which Windows shows as 80 TB. All of it is usable, and none of it is protected. If any one of the drives fails, everything on the array is lost.

Size printed on the drive label. Different sizes? The array uses the smallest one for every drive.

MB/s

Typical hard drive: 100–200 MB/s with no other load. SSD: 400 MB/s or more.

From the drive datasheet. It is a worst-case spec, so real drives usually do better.

Rebuild

RAID 0 cannot rebuild. A failed drive means restoring all 88 TB from a backup. With a typical 1.5% annual failure rate per drive, the chance that one of the 4 drives fails within a year is 5.9%, and within three years 17%.

Our take

Use this only for data you can copy or download again: scratch space, caches, a game library. With the same 4 drives, RAID 10 gives 44 TB and survives a failed drive.
