RAID 10 – Striping on top of multiple RAID 1 (mirrored) sets,
with one or two spare disks. RAID 10 provides good performance
for random writes, in addition to the highest availability.
RAID 50 – Striping on top of two RAID 5 (distributed-parity)
sets, with one or two spare disks. RAID 50 provides a good
balance of performance (especially for sequential writes),
availability, and capacity. RAID 50 is the only supported RAID
policy for a PS5500 array.
RAID 5 – One RAID 5 set, with one spare disk. RAID 5 is similar
to RAID 50, with more capacity (two additional disks) but lower
availability and performance.
