I need it for compatibility reasons. Some of my software won't work without a SCSI drive but that's another story. I've got to have one unfortunately, so if I'm going to pop one in there, I want it to be as silent as possible.

I don't know much about the different types of SCSI connectors but it's looking like to get a quiet drive, I'm gonna have to find some sort of adapter. There's an internal 50-pin on the 9600 and most of the drives I'm seeing are either 68 or 80 pin. I hope I can find a solution.
