Well, I just tried it on my machine (old, slower disk controller, medium fast SCSI disk (Quantum)). Read 3Meg file into memory: 609K/s. Copy 3 meg file (on slightly fragged partition) to another file on the same disk partition: ~550K/s. On a newer controller with a fast SCSI disk (170Meg CDC): ~900K/s and ~800K/s. These times are on Amiga 2500's with A2090 and A2091's using asynch SCSI. -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.cbm.commodore.com BIX: rjesup Common phrase heard at Amiga Devcon '89: "It's in there!"
