Thank you John. I'm pretty sure that raid 5 or 6 would be safe, since there is parity checking, however it sounds like this may not be the case for raid 1.
the parity on raid5/6 is only checked if you run some sort of scrub, and its used to regenerate a failed drive onto a spare or replacement... in normal operation, reads will be distributed to the individual drives that contain the blocks in question.
