you
could get up to 8-10MB/sec with 3490s -- which is in the same
ballpark as most of today's DASD.
Doing an FDR backup of a single disk to DUMMY, to get pure disk I/O
rates, we have been able to achieve 70MB/sec and more on FICON channels
with fairly current disk hardware from several vendors.
Its been my experience that disk and tape speeds tend to leapfrog. A
new tape model will be faster than most disks, then new disks will
outpace it, etc.
For example, the new IBM TS1120 claims up to 100MB/sec transfer rate.
