Apparently the SCSI I received my new Gateway 2000 386/20 a few days ago. It arrived with a Seagate ST296N and SCSI controller (not sure of the model #). Transfer rate was one of my reasons for purchasing this system, and I was assured prior to the purchase by the salesperson that I could expect 800KB/sec. I was quite disappointed when both Spintest and Coretest 2.7 gave me data transfer rates of 440-460KB/sec! Then, just today Mark Davis , reported that some users are seeing transfer rates of 950KB/sec! The interesting part is that when I called Gateway, the salesman immediately began reciting what sounded like a prepared statement to the effect that Seagate had lied to them! Then he quickly offered me a ST4096/DTC controller combo as a replacement, with a transfer rate of 550KB/sec. It's in the mail. If someone out there is actually seeing transfer rates around or over 800KB/sec, I'd sure like to hear about it. P.S. The drive documentation supplied with my system says the interleave is 1:1. And the access time, rated at 28ms, is measured at 33.7ms by Coretest. -- Byron Lunz Tektronix Logic Analyzer Division byronl@copper.MDP.TEK.COM Beaverton, Oregon
