WDBAAF0010HBK-EESN Replacement of WD 1 TB Essential

I had given my hard drive for replacement on the 3rd March 2012 . Updated by WD that they have received the Hdd and will soon ship as soon as they get the required stock . I am confused that will I get the USB 2.0 or USB 3.0 ? 

Does anybody has any idea about it ? 

This is a users forum, you can have an answer to this question by contacting WD.

you’ll get the same type of drive that you sent in.  unless of course their out of those drives, and can’t get them in.  then you might get an upgrade.  otherwise, vadir’s right, you will need to contact them to know more.
