RAID 10 – Mirror/Stripe
RAID 10 combines the properties of RAID 0 and RAID 1 logical drives. RAID 10
increases performance by reading and writing data in parallel while protecting
data with duplication. Four physical drives are required for RAID 10. One drive
pair is mirrored together then striped over a second drive pair.
Figure 4.
RAID 10 mirrors data over one drive pair and stripes it over the
other drive pair
The data capacity is similar to a RAID 1 logical drive, with half of the total storage
capacity dedicated for redundancy. An added plus for using RAID 10 is that, in
many situations, RAID 10 offers double fault tolerance. Double fault tolerance
may allow your logical drive to continue to operate depending on which two
physical drives fail.
RAID 10 logical drives on the AMD SB6xx/SB7xx Controller consist of four
physical drives.
