an important consideration is error handling. cheap consumer SATA
drives tend to delay error reporting as long as they physically can,
doing many retries to try and recover the data themselves without host
system(controller) intervention. the RAID controller would rather know
about the error itself.
enterprise and server grade drives are qualified by the raid vendors to
operate correctly with the controller error handling mechanisms.
