Well Mark, I think you should think buying one more drive.
Prebuilt NAS are shipped with disks from the same series. It is not unusual 
for drives built at the same time to fail at the same time (few hours). That 
have been seen in many datacenters: the second drive could fail while 
replicating on the replaced one.
Just replace one drive with another one, and if you think having two different 
drives would impact perfs, then put the original one it in few weeks or 
months.
