Seagate FreeAgent GoFlex Ultra

Seagate FreeAgent GoFlex Ultra

The FreeAgent GoFlex Ultra is the upgrade to Seagate's excellent FreeAgent GoFlex Pro by upping the storage amount to 1.5TB, making it the largest single volume portable external hard drive to date. The drive is also the first in the GoFlex family that supports USB 3.0 out of the box. Other than that, the drive shares Seagate's GoFlex family's superflexible detachable adapter design, allowing it to instantly change the types of connections it support. The GoFlex Ultra disappointed us a bit with its comparatively low USB 3.0 performance, unfortunately, though it was still really fast in our tests. However, even with this shortcoming, at around $250 for 1.5TB, it's still one of the best portable external hard drives on the market. The GoFlex Ultra comes in the exact same physical shape, size, and color as the GoFlex Pro. On the inside, however, it has two major improvements. First, it comes with 1.5TB of storage, while the GoFlex Pro has just 1TB. And second, out of the box, the Ultra includes a USB 3.0 adapter. Even though GoFlex Pro also supports USB 3.0, it comes with USB 2.0, and you'll need to pay another $40 or so to upgrade it to USB 3.0.
