Introduction

While the previous products QNAP offered basically kept increasing storage capacity by adding more drive bays, the TS-509 Pro actually offers a serious hardware upgrade.
Upgrading the CPU to a 1.6 GHz Celeron backed by 1 GB of DDR2 RAM should prove to increase performance, as previous models were bottlenecked by the low-power but relatively slow ARM CPU.
