Ok so i have 2 WD 250gb harddrives 7200 rpm 16 mb cache. I have never set up a raid but have been trying to look into it. I have a gigabyte ud3p mobo. I want applications to open up faster. I read parts of the raid 101 and it said raid 0 would give me better performance. I just picked up the second drive because it was a good deal but will I have to wipe the other drive I have been using to set up the raid properly? Thanks.
