I am professional photographer so I have alots of data when all dasktop drives full than I can only trust WD external hard disk ( 4TB 3.0) why I am trust this product because if yu have a cloud data you wont lost any data but you have no cloud backup you dont worry this hard disk easily recovered.
the most imported featutrs for WD external hard disk are reliability, speed( 3.0) , capacity and warranty support and good customer service. I am happy with WD hard disk.
