Note: The actual drive interface speed (MB/s) is the minimum value of the maximum supported speeds of the drive, the enclosure and the IOA. Also note that the minimum value for the various drive & enclosure combinations are identified in the above table.

Not all disk enclosures support the maximum number of disks in a RAID set.
