I was wondering if I could be able to set up my default hard drive and a new external hard drive for RAID 0. My internal disk drive is a ST3160815AS ATA Device (149 GB, IDE). And I have a My Passport Essential 500 GB USB 2.0 Portable External Hard Drive WDBAAA5000AD6-NESN. Will I be able to have a RAID 0 array with these and if so, is it worth it? Any information on this will be greatly appreciated.
