Description
WD’s My Cloud EX4100 is a downmarket Marvell-based version of the top-of-line Intel Atom based My Cloud DL4100 reviewed a few months ago. There’s also the two-bay EX2100 we won’t be reviewing, if you prefer your NASes in RAID 1 form with a slightly slower processor and half the memory.
WD sent a 16 TB WDBWZE0160KBK model as our review sample. But the EX4100 also comes in diskless (WDBWZE0000NBK), 8 TB (WDBWZE0080KBK) and 24 TB (WDBWZE0240KBK) models. As we did with the DL4100, we’re showing the 0 TB BYOD model for pricing, so you can more easily compare to other BYOD NASes. WD uses the “Red” series of NAS-optimized hard drives for all diskful My Cloud SKUs.
The EX4100 and DL4100 share the case design shown in the callout graphics below, pulled from the DL4100 review.
