Perhaps WD has written to the NAS because they use their well-known and popular NAS hard drives of the RED series in the housing.
The case seems to quite high, on the back in addition to the USB 3.0 input and 2 outputs (for other plates, if you will) to find and the power supply connector.
The hard drives are in the housing on the narrow side and from above by a plastic hinged lid and an accessible manually screw accessible. A fan does not exist and because of the quiet and economical heat RED disks not absolutely necessary, the air moves as in a fireplace from below upwards. However, one should neither cover up nor down, because then the plates are quickly die of heat strokes. The noise of the housing is very inconspicuous, who wants to save his movies on the device and play them in the living room, is in good hands here.
The software is provided exclusively on the device itself and should be backed up externally before switching to another mode, because otherwise it's gone!
Since I do not need the RAID capability, I have the housing via the software (on the case are no switches) switch to JBOD, while the individual disks are displayed separately in the operating system (by the way, contrary to the searchable in case badge named 1 2 and 2 is 1).
A problem that in an emergency can be very serious, however, is for me, even noticed. For testing purposes, I wanted one of the plates (already described with data) use in a single housing: But that does not work! Because the hard disk is recognized by the operating system as a new board and this will initialize it back again and then all data is gone! Even overwriting the first 100 MB (with a dedicated tool) on the disc in the other housing has not changed to this behavior, on the contrary, even in a third simple case, the plate was again recognized as a new and uninitialized.
This means in case of emergency, that requires an absolutely identically constructed housing to the hard drives can be accessed again. And something like this is for a large amount of data as present here a big disadvantage. Even Raid 1, so the uniform mirroring the data is only as secure as the RAID controller, which it fills. Turns out this, the data is gone.
For this problem, I have deducted a star.
