I have always liked SCSI myself. On the Sun workstations at work, all they use
are SCSI. My home system (P166MMX) has SCSI which is onboard an IWILL P55TV
motherboard. This is equivalent to the Adaptec 2940U Ultra SCSI. They also make
a Ultra Wide and new Ultra2 SCSI motherboards.
There is a slight price advantage to having it built-on, and it uses one less
PCI slot.
SCSI has advantages with respect to the number of IRQ's used (only one for up to
15 devices on a WIDE controller), and the performance in a server is better than
EIDE. Some things just work better as well. We have a P-II 266 system running NT
and an IDE based CD-R drive at work. I can't burn CD's at 4X without getting a
buffer underrun. This would likely not be a problem if it were a SCSI drive.
The downside is that it is more expensive. The controller carries a premium
(especially Adaptec, but I have never had a problem with Adaptec), and the
drives typically carry a price premium as well.
