We are not stuck on SATA. The whole data directory has ~ 80GB of data so PATA would work just as well. I did not see any docs on the LSI site for the 150-2. A Google search on it had produced a couple of listings that indicated it was not hardware RAID. I'll try and dig around some more on the LSI site to see what I can find. If it is an auto RAID-1 card that would work fine.
