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.

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

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
They do run hot, ensure the 'air hole' isn't covered up and that they've got
decent air flow around them.
