When it comes to larger file transfer, the WD My Passport Essential 500GB is quicker. But on the bright side, the Smartware Pro doesn’t consume a lot of processing power unlike certain live backup solution in the past. Still, large file transfers could be bit better. If you don’t mind waiting for about couple of minutes depending on the size of the bulk transfer it shouldn’t be an issue for a lot of people.
On another bright side, North American users get to enjoy 3 years of warranty period. As far as the drives I’ve tested so far, ADATA provides 3 years warranty to all continents.
