Kivolowitz) Organization: Whole Earth 'Lectronic Link, Sausalito, CA Lines: 14 Summary: SCSI XFer rate Means Nothing The rate at which a disk will squirt data to a controller is insignificant (on the Amiga) compared to the time it takes for the drive to have the data available and the time lost by within the o.s. It is precisely here that the SDP will do its magic. A) Replace DOS. Run the entire file system code right on the controller. B) Pre-Fetch most data accesses. Oh, by the way, if I am not mistaken, we use 3MByte per second SCSI chips. But as I said, this doesn't mean anything for other peoples controllers. Ours is the only one which would feel constrained by 1.2 Mb/sec Xfer rate. Perry Kivolowitz - ASDG Incorporated
