The Gigabit, BTW, has run like a champ. I've got an abit be6-II with p3-866 512meg, running 5.0 never crashed on me once, not had a single problem with it under fbsd - Rock solid. >> Finnally(sic) if you can afford it scsi is diffenetly(sic) better than ide, >> but >> I'm sure most people will think that is over kill. >IDE drives can be flakey(sic) on their DMA support.

Subsequently in that same machine I've got 2x IBM deskstar's (20gig 60gxp's) running on a promise tx pro2 as raid-0 (at udma100) again without any problems I think it depends on your mother board chipset, but both my intel (bx) and via (kt266) have run in dma without any problems under 4.x and 5.x. Scsi is definatly the way forward (if you can justify the cost) it handles more concurrent connections better, plus the lower seek time makes quite a bit of difference. I only fit deskstars in my machines - they've been good to me over the years. They do run hot, ensure the 'air hole' isn't covered up and that they've got decent air flow around them.
