According to the Linux-IDE project homepage, the ONLY IDE devices that
support hardware RAID are the 3Ware cards and the ARCO Duplidisk
devices: (http://www.linux-ide.org/chipsets.html)
ANYTHING else (including the HiPoint and Promise chipsets that are
generally what you get on motherboards that claim "built-in RAID
support!") require driver-level support to do any RAID at all:
(http://people.redhat.com/arjanv/pdcraid/ataraidhowto.html), otherwise
they act just like non-RAID chipsets.
So far I've never seen a 3Ware chipset built into a motherboard.
SCSI RAID, on the other hand, does exist on motherboards, but
motherboards with built-in SCSI RAID capability are much more expensive
as are SCSI drives, so I'm assuming we're talking about IDE.

Yep, and we use them at NKS. Make SURE you have the latest firmware
though! Earlier firmware was pretty buggy (in our experience) but the
latest versions work fantastic.
Even our own Ian Blenke was pleasantly surprised when he bought a 4-port
3Ware card. And Ian isn't usually happy with hardware until he's had a
chance to break it several times. :)
