Seagate FreeAgent GoFlex Ultraportable Drive
Uses: USB 3.0
Dimensions: 4.7 inches by 3.5 inches by 0.87 inch
Probably the most practical of the drives discussed here, the Seagate FreeAgent GoFlex is also the largest, with a colossal 1.5TB crammed into a 2.5–inch portable enclosure. The drive is a little thicker than less capacious portable hard drives, but we’ll cut it some slack in view of its vast capacity. Another consideration: This unit is a classic hard drive with spinning platters.
