Idk sometimes its a fraud and won't know until you actualy get the thing -->

But a good rule is to check Ratings, Reviews, Number of HDDs Sold, and how long has the seller been on AliExpress ; these factors should help you make a clear on whether you should trust this seller or not.
And remember: if it's too good to be true, it probably isn't (isn't good or isn't true :3 )
Best of Luck!
