NOTE:
The Device RPM number does not represent a rotational speed for the drives
without spinning media (SSD). It is meant as a rough estimation of the performance
difference between the drive and the other drives in the system. For FC and NL drives,
the number corresponds to both a performance measure and actual rotational speed. For
an SSD drive, the number is to be treated as relative performance benchmark that takes
into account in I/O per second, bandwidth, and the access time.
e.
RAID Type - Select the appropriate RAID type for the volume.

KiB for RAID 0 and RAID 1, and 128 KiB for RAID 5. If SSD drives are used, the step size
defaults to 32 KiB for RAID 0 and RAID 1, and 64 KiB for RAID 5. For RAID 6, the default is
a function of the set size.
