Well, I have had 3 computers over the last 4 odd years and all ran a raid 0 and i have not lost a single file due to drive failure or array corruption ( Touch wood ),
If you really just want maximum storage and are really not hell bent on keeping a raid array i would clone the array over to your single drive and then change your boot order and use that as your main system drive. I would then make sure you can boot to the new drive and then go in and and delete the array and reformat the 2 drives as seperate, I would partition a 30 or 40G section in one of them and then clone a copy of your drive back for a backup copy, the rest you can use at your leisure for whatever you like
