3 USB problems & overheat questions

I need to purchase several 2 or 3 TB portable drives. Research indicates either Seagate or WD.  There ared many complaints on WD drives stopping when loading large batches. The problem seems to be either the 3 USB cable or over heating.  Has WD fixed this (or these) problem?



Personally I haven’t experience this case.

I normally copy large amount of data and I haven’t received any errors. 

I have a WD Passport 2 TB unit since May 2013 and no a single issue with it.
