Not to start a holy war, but there are real reasons to use SCSI.
The big ones are
Much larger MTBF, faster access times due to higher spindle speeds, better bus management (eg 2 drives can perform tasks at once unlike IDE), Hot Swapable (This is HUGE) and more cache on the drive.
I'll stop now before I start that war :-)

Heh, there's a religious war waiting to happen.

I've just found that iostat (in unstable's sysstat package) supports extended I/O properties in /proc if you have sct's I/O monitoring patches. Unfortunately, the last one on his ftp site is for 2.3.99-preBlah. I sent an email to lkml last night to see if there's a newer patch - I'll follow up here if so.
Thanks Russell,
