When, not if, a drive fails, will you find one with precisely the same
geometry / capacity to replace the failed drive and remirror?  Can you do
so before the other drive fails (which might be statistically likely)?

There are good online MMTDL, MTTF, MTBF numbers for various raid levels for
ZFS. None would lead me to be so glib.
