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."
