Does the USB NAS have a drive/partition size limit? The ASUS 56 router does. How is the NAS speed?
I have a 750 GB USB external drive hooked into the router. No issues. Transfers are quicker than with my old router, but still USB 2.0 speeds. This router would be a grand slam with USB 3.0 ports. Surprised it didn't have them, but it wasn't primary reason why I bought it. Needed the wireless speed and extra range, and I have that in spades now.
