I think the ide controller in my machine at home is a 20267, which I
haven't had problems with so far.  Different model with I believe a
different driver, so who knows.

Real hardware raid makes life simpler and reduces cpu load and such.  It
can be great.

The current crop of cheap integrated raid on the other hand is a bios
extension that allows you to boot from what is otherwise just software
raid, and once booted the device driver takes over running the software
raid.

As far as I know all hardware raids rebuild while useable (as does linux
software raid), which I have read is not the case with the promise
raids.  They have to finish rebuilding before you can boot.  I hope what
I have read is wrong, but then again it wouldn't really surprise me much
if it was the case.

Something like a 3ware card on the other hand would be really nice to
have.
