4.5.2.6 Using Manual
Configuration: RAID 10
RAID 10, a combination of RAID 1 and RAID 0, has mirrored drives. It breaks up data into
smaller blocks, then stripes the blocks of data to each RAID 1 drive group. Each RAID 1
drive group then duplicates its data to its other drive. The size of each block is
determined by the stripe size parameter, which is 64 KB. RAID 10 can sustain one drive
failure in each drive group while maintaining data integrity.
