am sure the likely issue is a bad disk, but I thought there might be a
chance this could be caused by possibly by something else.

I bought specifically for this purpose. One is a Seagate drive that came
out of a barebones PC that I replaced with a couple smaller drives in a
stripe to gain performance. I use the drives in an external SATA dock,
using geom eli encryption, the western digital drives give me no
problems, but the seagate drive gives me a lot of the following errors
under load.

Try upgrading your system to something a little more modern.

Its running 9.0-RELEASE-P3 updated from source from an
original install of 8.2 on this hardware. 

I have done the firmware
update on the drive, so hopefully I will see an improvement in about 2
hours when tonights backups kick off.
