On another note, I took the failed drive I replaced in my array

Another type of drive test you can do is with smartctl:

smartctl -t conveyance /dev/sdX
... typically takes a couple of minutes
smartctl -l selftest /dev/sdX   # to monitor progress / completion

smartctl -t long /dev/sdX
... typically takes 6 hours on a 3TB drive
smartctl -l selftest /dev/sdX   # to monitor progress / completion
