WD My Cloud EX2100 Dual Bay 8TB NAS Review
WD My Cloud EX2100 NAS Hardware
The back side of the system has a fair amount going on, including a pair of Gigabit Ethernet ports for redundancy, failover and easy daisy-chaining. You also get a USB 3.0 port for additional expansion, as well a Kensington lock port and that all important reset button.
The back of the EX2100 shows dual-Ethernet ports for scaling, but just one power port.
By default it’s configured to have the drives inside running in a RAID 1 array right out of the box, so you just have to plug them in and you’re good to go. The array is already built and the OS in installed to built-in memory. If you want more storage you can change the RAID setup to RAID 0 or JBOD as well, but since there's no redundancy in that configuration you should make sure you have a backup in case of drive failure. The drive bays are tool-less and hot-swappable, so it’s quite easy to replace a drive. You'll also note the dual Ethernet ports, which allows you to daisy-chain WD NAS drives to one another to easily increase your network storage, without the need to reconfigure users when you link them together.
The two drive bays are a cinch to open and close, and require no tools or struggle.
