Part of the problem is that Exabytes are faster. Many SCSI systems just cannot keep the Exabyte streaming at 240+ KB/sec AND read the disk at the same time. The slower DAT system (125 KB/sec I think) gives the OS more time to read and format disk data without dropping out of streaming mode. Marc Kaufman (kaufman@Neon.stanford.edu)
