@kangaBurg – Your brother knows his stuff. Since he can install a RAID 0, why doesn’t he go ahead and put a SATA disk array of three drives in your PC? That would be better than your current setup.
SATA drives can transfer up to 6 gigabits of data each second. Doing a RAID with three of those will increase your computer’s performance even more. You also won’t have to do any backups, because the RAID configuration will keep your data safe.
