Can I use a newer SCSI drive on an older SCSI controller or vice-versa?
SCSI standards are backward and forward compatible. This means you can use a brand new SCSI 3 Ultra 320 drive on an older Ultra 2 Wide LVD controller. However, the drive will only be able to perform at the Ultra 2 Wide speeds. You can also use an older drive on a newer controller, but the old drive will not gain the performance of the newer controller.
