The protocol used by the device, e.g., FC or Serial Attached SCSI (SAS). Speed of the specified disk. (RPM) 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.
