Group Field Description

Types
Device Type
The type of physical disk, either Fibre Channel (FC), Near
Line (NL), or Solid State (SSD).
Device Speed The disk speed.
NOTE: The Device Speed 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.
