Description Field Group
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.
