At first glance the QNAP TS-453 Pro has little in common with the TS-453mini we recently reviewed, however they share a fair amount of hardware. In particular both NAS are powered by a Celeron J1900 processor that is paired with 2GB or 8GB of DDR3L memory, and naturally they both run on QNAP's QTS software.

We are also pleased to see that both models come with a decent array of USB 3.0 ports for rapid data transfer from external devices.
