The Seagate FreeAgent GoFlex 1.5TB portable drive isn’t the first of the company’s modular external storage we’ve reviewed, but it’s certainly the largest. Proudly billed as the industry’s first 1.5TB portable external drive, the new FreeAgent also boasts a speedy USB 3.0 interface for faster data shuffling. Thanks to GoFlex, meanwhile, you can also switch that out for FireWire, eSATA or other connections, or even slap it in one of Seagate’s docking stations. Is this the best portable drive out there? Check out our full review after the cut.

Available only in glossy black, the new 1.5TB FreeAgent measures a reasonable thick 4.71 x 3.51 x 0.87 inches and weighs 0.62lbs. It comes pre-fitted with the GoFlex USB 3.0 adapter, a dongle that snaps onto the HDD’s SATA port and has a short USB 3.0 cable. Seagate preload a copy of their Memeo-based backup software together with an NTFS driver for Macs that allows OS X users to access content without needing to reformat first. Unfortunately you’ll still need to reformat as HFS+ if you want to use Mac backup software or Apple’s own Time Machine utility.
