As Adam said, your drives haven't failed, but they are on the way out. Pay close attention to Reallocated_Sector_Ct, especially if it starts jumping upwards. You might also want to check the thermals; the Seagate is running at 52C, which is significantly hotter than it ought to be, except for maybe a laptop. I'd much rather see a drive running below 40C.... If you haven't rebuilt the mirror already, running a full disk read scan against both drives (ie, via "dd if=/dev/ad4 of=/dev/null bs=1m" or similar) might be prudent. That will help identify/migrate any sectors which are failing but still recoverable via ECC to the spare sectors.
