3590 tape drive performance depends on the model.  The latest E1x models
write at 14 MB/sec raw, with a maximum sustained rate on SCSI of 34 MB/sec
 (with compression) and 42 MB/sec of FC with compression.  Burst rates are
higher, 40 and 100.

An excerpt from the Magstar Redbook.   SG24-2594-02


"The Magstar tape drive is capable of reading and writing data at a rate
of
9
MB/sec. This is three times the rate at which IBM 3490E devices can read
and
write data. The IBM 3590 High Performance Tape Subsystem can transfer data
between the host and the tape subsystem at a rate of 20 MB/sec for hosts
attached through small computer systems interface (SCSI), and a rate of 17
MB/sec for hosts attached through Enterprise System Connection (ESCON)
channels."
