I've read the last few months of posts, and I'm still confused about something. If chipsets such as the Promise PDC20265 and Highpoint HPT372 are just extra IDE controllers, is the *only* reason for the special linux support to be able to share arrays with windows? And the $64,000 question (or maybe the $50 question :-) If I'm not going to run windows on a machine, is there any reason to get a motherboard with a "RAID" controller? The only reason I can think of is the extra IDE channels; if I do get a RAID board for this reason, is there any reason not to use /dev/mdX? Marc
