This WD passport drive (USB 3, sata drive) is as fast as lightning when used in an USB 3 port. Amazing speeds and the best portable external drive I have owned to date at a reasonable price.
I have owned Toshiba, Seagate, and Western Digital drives and to date, I have never had any problems with WD.
I have a desktop external My Book home edition 1TB drive from WD for three years now and still runs like a champion.
The only thing I didn’t like was the case. It is made of a synthetic rubber probably neoprene and has an overpowering chemical smell to the point that the case cannot be used. I almost passed out from the smell and I am afraid to bring the case home in the presence of my children.
