RAID 10: How many disk drives should you use? The minimum number of drives required for RAID 10 is four. RAID 10 disk drives are a combination of RAID 1 and RAID 0, the first step of which is to create a number of RAID 1 volumes by mirroring two drives together (RAID 1). The second step involves creating a stripe set with these mirrored pairs (RAID 0). In its original form this was called RAID 1+0, but has been abbreviated to RAID 10.
A 1TB drive might format out to about 900GB. The type of RAID also affects your usable capacity. Most RAID arrays will allow you to have one (or more) global hot spare, a disk waiting to step up for a failed drive in a RAID group, which would begin rebuilding the redundancy on that drive after a disk failure.
