Limited Drives on My Cloud Expert Series EX2 Ultra

Can anyone explain to me why the list of drives is so limited for the My Cloud Expert Series EX2 Ultra? I have several WD 1TB SSDs and am not sure why they cannot be used, especially if no RAID is setup…

ALSO, even WD cannot tell me the SHIPPING weight of the 0TB product. I KNOW the item is 1.8# (data sheet) but I arrange international shipping and have to pay $21/ kg. and nobody can tell me the PACKAGED weight. (My Cloud Expert Series EX2 Ultra 0TB)

Hi,

The WD My Cloud EX2 Ultra supports WD Red (upto 14 TB) and WD purple drives (upto 6 TB).
