Hi [MENTION=319412]manna@u[/MENTION],
I agree with [MENTION=159164]$hadow[/MENTION], each WD product have different specification and different purpose of use.
The main difference between them is that WD My Passport Ultra incorporates a hardware encryption, and WD Elements does not.
Also, WD Elements comes without any software, whereas WD My Passport Ultra has a lot of features with it.

Just a suggestion, if you don't have the budget problem and looking for backup device, then WD My Passport Ultra is the way to go. It comes with the full version of the WD smartware Pro software. It's a pretty simple and straight forward backup software that uses minimal PC resources. Set it up once and you can forget about it
