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.
State of the disk as identified by the kernel.
State
Total amount of usable storage for this disk drive.
