If you're looking for a portable and flexible external hard drive to accompany your USB 3.0-enabled laptop, at $100, the GoFlex Slim definitely makes a good buy. The Slim also supports USB 3.0 out of the box and offers fast performance. The new design alone makes up for its slightly higher cost per gigabyte compared with the rest of the family.
The 320GB Seagate GoFlex Slim differentiates itself from the rest of Seagate's GoFlex family of portable external hard drives, including the excellent 500GB GoFlex Pro, by being about 40 percent thinner, at only 9 millimeters.
