5-7] What SCSI adapter should I use with a CD recorder?

(1999/10/20)

Some systems have SCSI built in, some don't. This section is intended for
PC users who want to add SCSI devices. Owners of SCSI-less Macintoshes
should use an interface recommended by Apple.

Using different SCSI adapters for the HD and the CD recorder used to be
recommended, but should not be necessary with non-ISA adapters. If your
recorder hogs the SCSI bus, though, the HD may not be able to keep the
write buffer full. Under some operating systems, particularly OS/2,
devices that support SCSI disconnect will work better than those that
don't.

In general, the faster the better. PCI or the (now uncommon) VLB is better
than ISA, and the board should support (and have enabled) SCSI disconnect.
It is not necessary to use Wide or Ultra SCSI for a CD recorder; the speed
requirements for all existing recorders are easily met by "narrow" Fast
SCSI. If you think you may be buying a speedy SCSI hard drive or other
device in the near future, though, you may want to buy a card that supports
faster protocols.

You should enable synchronous transfers for devices that support it. Most
CD recorders should. If the device doesn't work with it on, turn it off
and try again.

The adapter MUST support the ASPI standard (ASPI provides an interface
between software and the SCSI controller) for both DOS and Windows.

If you want to boot from a CD-ROM on a SCSI drive, make sure the SCSI card
supports booting from removable media.

The next few sections detail the more popular SCSI cards. There are
many others, e.g:
