There are some really good RAID Primers you can read up on, like this one=20
from Intel:
http://support.intel.com/support/motherboards/server/raid_info.htm

or this one from LSI:
http://www.lsilogic.com/products/stor_prod/raid/backgrounder1.html

or this one from Adaptec:
http://graphics.adaptec.com/pdfs/ACSP_RAID_Ch4.pdf

really well for us, but I don't have much experience in the IDE RAID realm=
=20
yet with the exception of the Adaptec/Intel SATA RAID built into the ICH5R=
=20
on the new S875WP1 server board that isn't yet supported under FreeBSD=20
(might want to stay away from that one for now)... Probably something from=
=20
Promise will suit you fine. At the low end, if it works, theres not going=20
to be a lot of difference among controllers.
