    I'm trying to setup my new mac pro and have a question about RAID. I have two 2TB harddrives and 1 640GB harddrive and about 1.5 GB data that I want to store internally. Currently I am using the one 2TB for the data with the other for backup with the 640GB unused. I've noticed access to some of the data is a bit slow, particularly music files in Itunes. If I set up the 640Gb and the 2Tb in Raid0 would that give me any speed improvement?

    You'd certainly see an improvement, however, the array size you end up with will be 640GB x 2, so 1.28TB.

    If you want to make a RAID0, use two equal sized drives.

    Honestly, the performance gains with RAID 0 would probably not justify the loss of space you'd see by using drives of different capacities.
