| DOes anyone konw of a SATA RAID controller that works under Linux.
Apparently the one no my K8V-X does not work properly.
I finally have no need for Windows except for a small partition for
itunes, which will be formatted FAT32, so I can read the music under Linux.

Most (all?) onboard RAID controllers are "fake RAID" -- that is, they
use the drivers to do the RAID in software. Said drivers are usually
closed. The best use of such controllers is to just treat them as
plain SATA controllers and do your RAID in software in Linux.
If you need a *real* hardware RAID controller, 3ware is your best bet.

Thank you. I'll give it a look. I want hardware RAID 0 for the speed,
so I'll give 3Ware a look.

A 3ware card will cost several hundred dollars. And for RAID-0 the
speed difference between software and hardware is almost nothing.
(Software RAID can even be *faster* than hardware RAID under some
circumstances.)
My advice: try software RAID first, before you shell out for a 3ware
card. And if you do buy a 3ware card, be sure it comes with a good
return policy in case you find its performance isn't worth the investment.
