RAID 10

RAID 10 is a stripe of mirrors that combines the features of RAID 0 and RAID 1. As the blocks are striped and mirrored, the
performance and redundancy are higher. The disadvantage of RAID 10 is that it is more expensive than other RAID levels, with a
higher number of drives required.

The following are the key features of RAID 10:

Requires a minimum of four drives. Only an even number of drives can be used, and an odd number of drives are not
possible.

The total volume capacity is half the sum of individual drives capacity. For example, when you use four drives of 1 TB, you
get a RAID 10 volume of 2 TB.

The following figure shows that the data is still available even if one disk drive fails in each mirror.
