The controller is fairly irrelevant (well, as long as it's a good one,
not just a PIO hookup monster like the old Seagate ST-01 :).

CD-R drives don't require a very fast SCSI bus, they usually only
write with so-called double speed.  That translates to 305 KB/s for
CD-ROM data, or 350 KB/s for raw (like CD-DA) data.  That's far below
any disk's rate today.

I'm pretty sure i could successfully use my aged AHA-1540A for the
CD-R drive as well.

Never trust an operating system you don't have sources for. ;-)
