Since you have a board which does not do RAID at all, so i dont know if there is any limitations on the HDD capacity.
The board has the Chipset ICH7. I will assume that it will have nearly the same features like the ICH7R/DH. It is best to check with someone else for this one.
There is a 2-256TB data volume limit support on this chipset.
I am currently using one that has a WD 1TB drive
