4 × 16 TB in RAID 0: the numbers
| Usable space | 64 TB (58.2 TB in Windows) |
|---|---|
| Raw space | 64 TB |
| Used for protection | Nothing |
| Efficiency | 100% |
| Drives that can fail | None |
Rebuild
RAID 0 cannot rebuild. A failed drive means restoring all 64 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 32 TB and survives a failed drive.
