Ok I have a new MoBo that has RAID support for 0 and 1 and I have two 1TB HDD's that I'd like to raid if possible.
Do the HDD's need to be the same brand and model or can the be different?
I want to use RAID 1, correct?
Also I have a 500GB HDD That i want to install the OS and programs on, is this possible?
Depends on the controller I think, but in general I believe they can be dissimilar drives.
RAID method depends on what you want - mirroring for redundancy or striping for speed.
RAID - Wikipedia, the free encyclopedia
Personally I would have the OS and programs on a striped array, with the "media" drive as a standalone, but that's just me.
