Introduction

Disk manufacturers who also make NASes have a price advantage over manufacturers of BYOD products. This is certainly the case for the recently updated My Cloud Mirror Gen 2. The My Cloud Mirror Gen 2 is very similar to the more business-oriented My Cloud EX2 we reviewed in March of 2014. The new Gen 2 has a different processor, a white case and the SOHO My Cloud feature set.

Our review unit was the $310 4 TB model. However, the Gen 2 also is available in a $370 6 TB version (2 X 3 TB) and a $410 8 TB version (2 X 4 TB). Each of the models arrives preconfigured for RAID 1 (mirrored), so your actual available fault-tolerant storage will be half the stated capacity.

Priced at $310 with two 2 TB drives included, the Gen 2 is cheaper than quite a few BYOD 2 bay NASes. I'll be using the Seagate NAS Pro 2-Bay and NETGEAR ReadyNAS RN202 for comparison throughout the review.

The Seagate NAS Pro 2 bay, like the Gen 2, includes two 2 TB drives in its $340 price. For a BYOD NAS, I chose the NETGEAR ReadyNAS RN202 because, priced at $250, it was the cheapest BYOD NAS that also had a better Total NAS score than the Gen 2. If you add the cost of two WD RED 2 TB drives at ~ $95 each, the total cost for the RN202 with an equivalent amount of storage rises to $440.

The callouts below were taken from the user manual. While WD has a support section with downloads for the Gen 2, the user manual isn't one of the available downloads. We found a link for the manual in the help section of the Gen 2's user interface.

The front panel is very simple - there's just a single power/status LED and a LED for each drive. A combination of red, blue or not lit coupled with various blinking patterns tells you what you need to know.

The image below shows the rear panel callouts and LED indicators. The single Gigabit Ethernet port has two status LEDs - one for link speed and one for activity. There is a pin reset, a Kensington security slot and two USB 3.0 ports. There's a small, very quiet fan positioned at the front bottom of the case that moves air across the drives and board. The Gen 2 was rated as very quiet and drew 14 W active and 6 W on standby with the two WD Red 2 TB drives spun down..

The image below shows the main board with the heatsink in place.

This image below shows the board with the heatsink removed to expose the processor.

This is a completely new board, not the same as the WD My Cloud EX2's. Table 1 below shows the key components for the comparison two bay NASes.

The My Cloud Mirror Gen 2 arrives preconfigured for RAID 1. There is no possibility for RAID Expansion. Changing to RAID 0 or JBOD completely deletes all data from the drives.
