Why do you want to use the "fake hardware RAID" of these cheap
controllers?  They are outperformed by Linux md and Linux md has the
advantage that it is portable and open source.

Silicon Image, Rocketraid, Promise, these all perform well, but I
would never ever use their "fake RAID".

I've had no issue using Sarge's Debian Installer to install to
Silicon Image SATA controllers.
