I have a Dell Dimension 2400 with a western digital 40 gig. hard drive# 400BB,7200 rpm. --- and I changed it with a Seagate 50 gig. SCSI  SX150176LC 7200 rpm. With Adaptec AHA-2940U/2940UW/2940D PCI SCSI Controller.  Both drives have Cluster size 4 KB. And I ran a performance test from passmark software  version 5.0 on both drives. The Seagate runs much slower. This is my first SCSI drive. The disk sequential write, read and the disk mark is very slow! It should be just as fast or faster then the western digital. Any ideas?

Is the SCSI chain terminated? SCSI termination is most likely set to AUTO on the SCSI controller (you can check by using CTRL-A as yiour PC is booting), but you should also have a SCSI terminator at the end of the SCSI cable (or last device on the SCSI bus).

BTW - were you aware that this is quite an old drive (1998/1999)?
