The CPU overhead occurs when actually accessing the array, not for mounting it.

Do remember that with a RAID0 (simple stripe set), if just 1 of the disks goes bad, everything is lost. Also, please don't consider different volumes/drives on the same machine as a good backup strategy. Things like bad/failing RAM or a bad/failing power supply could corrupt any/all disks in the system. It may see like a remote case, but things like this do happen -- My Murphy loves to make fun for you. Depending on your specific needs, you may be better putting those disks in a different machine and making the copies/backups over the network. This scenario removes many more failure points.
