Ok, so mirrors resilver faster.
But, it is not uncommon that another disk shows problem during
resilver (for instance r/w errors), this scenario would mean your
entire raid is gone, right? If you are using mirrors, and one disk
crashes and you start resilver. Then the other disk shows r/w errors
Those using mirrors or raidz1 are best advised to perform periodic
scrubs. This helps avoid future media read errors and also helps
flush out failing hardware.
Regardless, it is true that two hard failures can take out your whole
pool.
