TBH, I don't like any of the full size 3.5" externals much and think they miss the point as a product category. They are clunky and need an external power supply, so moving them between computers or carrying them with you will be more hassle than it's worth. For stationary storage that always stays at home there are other things you should be considering --
NAS or just a plain internal drive if you use a desktop.
On the other hand, the portable external drives like the
WD Passport are awesome because of the size and the fact they are powered from USB and don't have a separate power supply. Since they are based on 2.5" laptop drives, you won't find any price/capacity leaders here, but they are very convenient -- and that's the point of having an external drive for me.
