I know everyone is strongly against raptor HDs but I think the 150 gig raptor I got for 165 after MIR was one of the best decisions I made ( I also got a 80 gig seagate for media storage ). I store the OS and all my games on the raptor and its great cause I dont have to deal with all the hassle of setting up the RAID and lose the double risk of HD data loss. Not to mention I heard my mobo has problems with RAID sometimes, I think its just so much worth it to dish out the extra 85 bucks. My time is worth so much more
