WD's next cloud storage drive EX4 comes with a digital display that shows information about the product such as IP of the drive so that users can access it easily. The NAS storage device is easy to setup. The device has both LAN and USB connection ports, so you can connect it to the network as well as directly connect with the PC using the USB port. Setting up the drive: It is packed in a metal four-bay enclosure and supports RAID 0, RAID 1 (two disks mirrored), RAID 5+Hot Spare (same as RAID 5, but with a spare drive installed and ready to become operational in the event of a drive failure), and RAID 10 (nested RAID).
