Does the drive come with all needed power and data cables in the box?
Yes, everything you need is included.
Does anyone know if the internal 3.5" Hdd is a WD Red or a WD Blue /Green…
And if so which has what…
You can use a program like HDTune to read the model # of the Drive for this info.
According to this teardown, which I did not perform:
WD purchased Hitachi’s HD operation in 2012. It’s possible they’re (still) using stock left over from the merger.
Actually, that’s the wrong model, these have WD Blue drives inside.
