Thank you for your feedback and we appreciate you taking the time to providing a review on the My Cloud NAS.
WD always recommends keeping your important data on two separate locations, the My Cloud NAS is a single disk NAS unit and does not have the same features as those of a multi bay unit.
The WD My Clouds are well ventilated and cooled by ambient air flow and with this in mind the units will function perfectly in any home situation. If the drive is unusually hot we would recommend running the internal drive diagnostics.
