WD My Book World Edition NAS Device
Design & Build Quality
The WD My Book World Edition earns the "Book" portion of its moniker because it is roughly the size and shape of a stubby hardcover book. The front of the drive is curved (perhaps simulating a book's binding), while the back has rounded corners. The device's chassis is made from white plastic, with the front and sides shiny. The the top, back, and bottom sections have a matte finish and have slits and holes in them for airflow--and which look somewhat like the pages of a book. A small, white and gold "WD" logo appears on either side of the drive. The chassis is made from just two plastic pieces, but it is not designed to be user serviceable--in other words, you're not supposed to be able to crack it open in order to swap out drives.
The front of the device features a vertically-mounted set of white LED status lights. There are six lights total, each representing approximately 17-percent of the drive's capacity. As the drive continues to fill up, more of the lights, from the bottom up, illuminate. When the drive is in use, the lights move up and down, somewhat reminiscent of the eye movements of old-school Cylons from Battlestar Galactica. When the device is in standby mode, the LEDs slowly flash on and off every four seconds. If you find the status lights annoying, you can always disable them.
The back of the unit has an RJ-45 Gigabit Ethernet port, one USB 2.0 port, the power button, a recessed reset button, and the AC adapter jack. You can hook up an external storage device (such as an external hard drive or flash drive) to the USB port, and it will appear as just another folder share to connected users. Unlike some other NAS devices, however, you cannot connect a printer to the WD My Book World Edition to use it as a networked print server. The bottom of unit includes rubber feet and a product label that includes the device's MAC address.
