Yes it's true of most IDE RAID you'll see, in particular those from
Promise and HighPoint which are often found on "RAID" equipped
motherboards. They implement software RAID, doing all the work on the
host CPU.
There are a few cards that do the processing onboard and the 3Ware
Escalade cards are probably the best of them. They come with up to eight
channels (but you're only allowed one drive per channel) and support
64-bit PCI. Adaptec have a proper IDE RAID card too. Probably worth
investigating though 3Ware have been in this market, and had Linux
drivers available, for much longer.
