Mirror would write slower, because it has to write everything twice, but read faster, because it has two places it can read from.
Stripe would write faster because you have multiple locations to "split" the files between.
Caution: Stripes, in the purest sense, are risky in that if you lose one drive, you might as well have lost them all.
RAID 5 is Stripes with Parity. Lose a drive, no big deal. You experience a performance hit when a drive dies, and just after replacing it because the stripes are rebuilding.
