WD My Cloud compatible hard drives

WD My Cloud EX2 Ultra

I have a diskless WD My Cloud EX 2 Ultra which I want to put two 4TB cmr drives in. The Hard Drive Compatibility List is very small on the WD support page (https://support-en.wd.com/app/products/product-detail/p/130). I ordered two WD40EFRX and was sent two WD40EFAx drives which I have sent back. I was think about geeting possibly two Seagate Ironwolf 4tb but they are not on the Compatibility List. I would like to know if anyone has put non WD drivers in the WD My Cloud EX 2 Ultra and it work.

Virtually any drive will work with a 2-bay system since all data is simply mirrored. If you have SMR drives instead of CMR then you would only notice a rebuild difference in RAID5 or RAID6.

WD compatibility lists are kept short since they want to sell their own drives. But you can see they have added Baracide desktop drives on the list which needs the same amount of power to run. Ironwolf drives are very similar. So yes, you can use Ironwolf HDDs.

Here is their compatibility list.

I hope this helps.
