Speed of the specified disk (in thousands of RPMs).

Device RPM

NOTE:

The Device RPM number does not represent a rotational speed for the drives

without spinning media (SSDs). 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.
