About the WD EX2 Ultra…

Earlier, the WD My Cloud EX2 NAS was tested. Naturally, you’ll ask what’s different with the WD My Cloud EX2 Ultra. The EX2 Ultra has a larger 1 GB RAM. Rest of it is the same. It uses the Marvel Armada A370 clocked at 1.2 GHz, it has JBOD, Spanning, RAID 0 to 10 support and the same housing. As always My Cloud has the same type of Disk and diskless choices, depending on your preference in storage capacity and budget.

The WD My Cloud EX2 Ultra’s packaging is no different from the EX2. This variant has two WD 4TB WDEFRX Red drives preinstalled. The foam on the NAS should be adequate to protect from any potential damage during transit. WD provides few packaging materials, a power socket with two plug options and an ethernet cable. There’s no installation disc but it is better to just get the required installers from WD’s website. The disk variant of the WD NAS units should have the firmware installed so its a matter of getting the WD installer and let it detect it.

The EX2 series have two USB 3.0 ports. This is a great add-on which has been in NAS units for a very long time.
