Considerations for
Drive Channel
Speed
When you connect multiple drive trays to the same drive channel, all of the drive
trays must operate at the same speed. If you plan to combine drive trays that operate
at different speeds on the same drive channel, you must set all of the drive trays to
operate at the lowest common speed. The following table lists the operating speeds of
each supported drive tray.
