My opinion is that complete hard drive failure and block-level media
failure are two totally different things. Complete hard drive failure
rates should not be directly related to total storage size whereas the
probabily of media failure per drive is directly related to total
storage size. Given this, and assuming that complete hard drive
failure occurs much less often than partial media failure, using the
copies feature should be pretty effective.
Would the use of several copies cripple the write speeds?
It would reduce the write rate by 1/2 or by whatever number of copies
you have requested.
