I dont really know anything about scsi thats why i am here i guess , anyway I was given an Adaptec 2940UW scsi Controller for christmas and . Im wondering what sort of internal scsi hard drives are compatible with it . I see all this ultra160, U320 , ultra 3 and Im confused as to what drive i can use with my new controller. I want to buy a scsi drive to speed up my system performance .. help on this appreciated ..Thnaks
