I did a scrub on my volume yesterday, please see the results below. Particularly I am wondering about the checksum errors (81) on the one disk as shown. Does that mean I need to replace it?
I did a zpool clear and it went back to zero...
Further, FreeNAS GUI says the volume is "HEALTHY" after the zpool clear. I should have checked it before that, but I didn't...whoops...
Now, I will add that I've ran this command to find out the real /dev/ device name:

It's a SATA II drive connected directly to 1 of the motherboard's SATA ports.
