[M] QNAP TS-563 5-bay Affordable Quad-Core Business NAS Review
 

This is not the first AMD-based NAS we are testing on MadShrimps and it has been demonstrated to us once again that the platform has potential even when dealing with a lower clocked SoC and to be more exact the GX-420MC. This quad-core component is lacking a GPU (hence we do not have a HDMI interface on the back of the unit), is equipped with a total of 2MB of shared L2 cache, comes with a power rating of 17.5W and a frequency of 2GHz per core. While the unit is initially equipped with only 2GB of DDR3L RAM, we always have the option to open it up and install up to 16GB (2x8GB).
