68 MB/s is quite a lot. I'm not sure what top-of-the-line SCSI disks
can do, but it can't be much more than 68 MB/s.
My CS20 is gets 63 MB/s with its Ultra160 drive.
160 MB/s is the theoretical maximum that the BUS can handle. In
practice the disks themselves can't shove data out that fast. If you
need more throughput than that you need a RAID array.
