I used to be a big SCSI fan, but to be quite brutally honest, SCSI is a standard that deserves unmerciful death. Sorry, but that's just how I feel and that is coming from some sobering experiences with SCSI. On pricing alone, you got $80 for a damned terminator here, another $60 for a Ultra SCSI to U2 SCSI HD adapter, and on and on and on and on and on. F**k that. Do a Format C: routine and install Windows clean on a SCSI? Good luck!! God forbid you're doing it on a system where the SCSI controller was integrated into the motherboard in a single chip solution.Serial ATA would be great. But it is vaporware. And it may always remain as vaporware. Ultra ATA is trying to incorporate RAID capability. But Firewire can do it better. And with Firewire2 looming on the horizon, the Ultra320 SCSI standard may certainly be rendered moot. Hell, with the bandwidth USB 2.0 supports we may soon be seeing USB 2.0 external hard discs. I'm rooting for things like Firewire and USB 2.0. ONE single type of cable connection. No f**king terminators or IRQs or "is this channel loaded up" nonsense. I realize SCSI is up to Ultra320 standards now. But you are still limited to 7 devices per channel and 15 devices total, with all the continued adapter and terminator headaches. I've had a few SCSI computers in my time and my dual PII 400MHz was pretty much the last I will ever stomach owning. Items like SCSI based Zip drives and CD-RW drives were extremely problematic. The freaking Zip drive never ever worked right. If anyone is going to buy any kind of new SCSI based system DO NOT under any circumstances buy anything where SCSI is integrated into the motherboard chipset. That is pure, utter garbage. I'm not very worried at all about the Macs running IDE drives standard instead of SCSI. With today's options, I say big deal. The IDE drives have enough I/O capacity and drive RPM speed to handle things like digital video streams. And then if you get into a situation where you need something better for brute force purposes, pick up a SanCube Firewire RAID disc box. One firewire cable, no terminators, no adapters, no headaches, just wide bandwidth drive performance.

Perhaps I didn't make myself clear.  Workstations and utility servers: IDE is perfectly good and much less expensive. SCSI is unnecessary unless you want the nth degree of performance and reliability, and cost is not an issue. Mission-critical servers: IDE bad. SCSI much better. Initial cost may be higher, but long-term reliability and performance are improved over IDE. Older SCSI ZIP drives and other external SCSI peripherals that require user configuration of IDs, termination, etc. are a pain in the ass and obsolete. Newer SCSI system designs for mission-critical applications DO NOT require messing with termination or SCSI ID numbers. I would avoid any such SCSI device like the plague (although tape backup systems still usually require configuration). Fortunately or unfortunately, most high-performance tape backup solutions for networks and servers are SCSI (or fiber-channel, or SAN). If a tape drive is IDE, it's a given that it's a consumer-grade piece of junk. Firewire, serial ATA, etc: Bring it on!
