USB Direct Attached ability vs Linux based Dual OS – the QNAP NAS comparison with TS-453A or TS-451A

Interested in buying a QNAP TS-453A NAS or the QNAP TS-451A NAS but cannot decide? What is more important to you, that wonderfully new Directed Attached Storage ability via USB 3.0? Or the fantastically innovative Linux Dual OS of the TS-453A via twin HDMI ports? There are any number of reasons to buy either of these NAS devices, but what we want to know is which unit is right for YOU! Robbie at SPANTV took the time to make a NAS comparison on these two devices in the hope to answer which of these Network Attached Storage servers is best suited for your home or business needs.
