The FreeAgent GoFlex Ultra-portable is an upgrade to Seagate's excellent FreeAgent GoFlex Pro that increases 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 supports.
The Good
The Bad
The Bottom Line
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.
