Those using mobile devices are instructed to browse to the IP address of the EX4 and use the Web-based setup. There is a specific URL given in the guide for downloading the setup software for desktop computers. The guide shows you how to connect the cables then tells you where to get the software for install, depending on what system you are using for setup. The EX4 ships with a quick installation guide. Setup is very similar to and as easy as the setup of WD's consumer My Cloud NAS. The native file system is EXT4 and file systems supported on connected USB external drives are FAT/FAT32, NTFS, HFS+J, and Linux EXT3 and 4. On the software side, the EX4 supports Windows XP SP3 and later and Mac OS X Snow Leopard and later. On the hardware front, it's a well-designed, attractive device. The drive bays have handles that make popping SATA drives in and out easy.

The EX4 is a four-bay NAS available in a diskless configuration ($349, street), 8TB ($749, street), 12TB ($899 street), or 16TB ($1000 street). However, the EX4 has a user-friendly interface, it offers easy-to-deploy remote access via Western Digital's My Cloud service, and it did a good job with system recovery in a simulated drive failure test. This isn't a NAS for an SMB that needs top performance from a storage device-one serving as a repository for a heavily-used database, for example-and it lacks some advanced features in other SMB NASes we've tested. With more storage than its consumer counterpart, plus business features, the EX4 is suitable for smaller business storage needs. Western Digital's My Cloud EX4 ( at Amazon) (Opens in a new window) is the business big brother to the My Cloud home-use NAS, released last year.
