Design and Build

The PR4100 has a slick design and adds value to the desk. As most of the workstations or desktops are black in colour, it fits in well with other components. In terms of dimensions, the My Cloud PR4100 is compact with 5.82 inches height and 4.28 inches width. On the front is the Status LCD display with scroll buttons on the left for easy navigation, then there are the Power and One-click copy button along with a USB 3.0 port, and four drive bay with status LEDs. Thanks to the Status LCD you don’t have power up a system or connect through a mobile to check a lot of things including IP address and drives statuses. If you work in dark or low light, then you can disable the Status LCD display and also save power.

But the main thing on the front are the four tool-less/tray-less 3.5-inch drive bays, that you can open by simply pulling the handle to swiftly remove or install a drive. Even though the latch mechanism is extremely easy to open or close, be rest assured that drives are very secure once they are snapped into place, and the doors are closed. But, if you are worried about drives being stolen or tampered with then, unfortunately, you can’t lock the bays with a key.

Moving on the back of the device, where are all the ports and the system fan. Don’t go by the huge fan that takes up the entire rear of the device as it is a very quiet device. The connectivity/functionality is located along the right side, consisting of a reset button, a USB 3.0 port, two Ethernet ports, and two external DC-in power ports. The Kensington Security Slot is placed at the bottom left of the back panel.

  2. Can this be used with different size HDs: for example 14 TB and 8TB? Also, can some of the bays remain empty?
