It's your money, but I miss any reason to go to SCSI for CD, since the
ATAPI devices cost less for any given performance, and as long as you
put each CD device on a separate controller you avoid the evils of the
bus. The money you save on not buying new SCSI CD drives would go to
buying disk or something which might work better on SCSI.
I'm told that in the next year or so ATAPI will be upgraded to allow
disconnect-reconnect and support more devices than two (but it's 16).
Since ATA100 already added CRC on the transfers, the advantages of SCSI
grow very small except at the very top end.
Every new generation of drive comes out in SCSI (read as: high profit)
first. But ATAPI is now available in 7200rpm, <8ms seek, which is where
SCSI was about two years ago. I'm buying a pair of super-Cheetahs,
15k-rpm, <4ms seek, for a critical application, but the backing store is
4x72GB ATAPI in RAID-5 config where performance is not critical.
The big advantage of SCSI comes when you need a lot of drives, and I
would never deny that. But for home use I would put the dollars into
memory, CPU, and a really good backup system. That's my opinion, as I
said it's your money, if SCSI makes you happy go for it. I use parity
memory to feel good, I understand running the best for some things.

Linux ide-scsi driver?
