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.
