THE MY CLOUD EX4 EXTERIOR
The WD My Cloud EX4 NAS is a medium to large sized 4 bay model that measures 220.2mm in length, 160.1mm in width and 208.6mm in height (weighs 3.3Kg without the drives and 5.8Kg with the drives).
To showcase its size we placed the My Cloud EX4 right next to the TS-451+ by QNAP and as you can see it's quite larger mainly because of the extra LCD screen.
Part of both sides is perforated to allow hot air to exit the enclosure.
The fascia is polished and aside the LCD screen and the 4 drive bays (each bay has its own blue status LED) it also has the on/off power button and two buttons with which you can control the information displayed.
Unlike most other manufacturers WD has used 4 tool-less (push-out), hot-swappable bays.
Our sample came fitted with 4 Red 2TB NAS Hard Disk Drives (previous NASware 2.0 version, 5400 RPM, 64MB Cache).
Moving at the rear we see a 90mm exhaust fan (2400RPM), two DC in power ports, two USB 3.0 ports, two Gigabit Ethernet ports and the reset button.
