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.
