Michael,

By far the best SATA RAID controllers with great support for Linux come
from 
3WARE.  If you only have 2 drives, you can get away with their basic
(~$120) 
model which can do RAID-0 and RAID-1, the 8006-2LP.  It works great!  We

have everything they make from the basic 2-port model all the way up to
a 
12-port models which run our 3TB storage backup systems.

Stay away from Adaptec and Promise controllers.  Promise controllers
have 
serious issues with drivers and stability, while Adaptec outright
abandons 
brand new products and doesn't provide almost any Linux support.  We had
to 
toss several dozen of their 'brand new' zero channel SCSI RAID 2015S 
controllers because they announced that they would not provide drivers
for 
kernel 2.6 - meaning FC2 and above, RHEL 4, etc.  They seem to be a
"Windows 
only" shop these days.  I know it has nothing to do with SATA, but as a 
company in general I wouldn't buy any of their products anymore, not
after 
spending thousands on controllers that we had to replace less than 6
months 
later because Adaptec decided they were going to support Windows only.
