Noooo...it would still be 1 in 1000 for each disk. If one crashed and
took the other with, then the odds would change to 1 in 500, but since
one crashing does not mean the other will crash at the same time, it
remains 1 in 1000 per disk.
Just the law of probability, if you have say a 1 in 1000 chance of a
failure with one disk then you have a 2 in 1000 (or 1 in 500) chance
with 2 disks.
