Cons
Con Slow GUI
GUI is almost unusable due to lag. Moving files around and organizing files already on the drive is a headache.
Con Available with Western Digital hard disks only
Buying this NAS pre-installed with non-Western Digital hard disks is not possible.
Con No data protection features
As with most single-bay NAS units, you risk losing all of your stored data in the event of a disk failure. You can still use an external USB drive to manually backup your files every once in a while, though.
Con Official documentation leaves much to be desired
The documentation lacks important technical parameters such as CPU, RAM size and type, power consumption and even read/write speed. The Western Digital web resource also doesn’t include a list of compatible applications.
