Shopping for an external hard drive usually means choosing the device that corresponds to the fastest port (most commonly USB 2.0) on the back of your computer. Although other connections, like FireWire 800, USB 3.0, and eSATA, are quickly gaining popularity for their impressive transfer speeds, most shoppers settle on USB 2.0 because of the premiums that companies charge for the extra ports.
Seagate proposes an alternative solution with its latest product, the FreeAgent GoFlex external hard drive, which features exchangeable "personality cables" that put the port selection in the hands of the consumer. At only $100 for the 320GB model, the Seagate FreeAgent GoFlex portable hard drive is well-deserving of our Editor's Choice Award and is a solid bet for budget-minded data gobblers who want to stay ahead of the connection curve.
Design and Features
The GoFlex shares many of the same design characteristics with the other drives in the Seagate FreeAgent Go lineup, including a 0.55-inch-thick case and a sleek, unassuming silhouette. Seagate offers the drive in four colors (silver, red, black, and blue) and a variety of capacities ranging from 320GB all the way up to 1TB, each at a fair price-per-gigabyte considering the increased functionality over "standard" hard drives (see "Cost per gigabyte" chart below).

The casing separates the GoFlex into two parts: the hard drive and a proprietary cap that ends in a USB 2.0 plug. To go along with this new drive, Seagate sells a variety of "personality cables" for $30 apiece to fit USB 3.0, FireWire 800, and eSATA, in addition to docks and accessories that let you access data on the go using software licensed from Pogoplug.
Inside the drive itself, you'll find a 2.5-inch hard disk that spins up to 7,200rpm, giving it an extra boost in speed compared with the typical 5,400rpm drives in most external hard drives, especially when paired with the USB 3.0 cable. And though the personality cables cost more than their standard off-the-shelf counterparts, they also offer you the flexibility of purchasing only the cords you need, while still leaving the option open for connection upgrades in the future. Product reps from Seagate tell us that a personality cable is in development that supports Light Peak, Intel's new cable technology intended to replace USB, FireWire, HDMI, SATA, and SCSI as the standard.
Another boon for the GoFlex family is its capability to access and exchange files between computers running both Mac and Windows operating systems. Seagate has partnered with Paragon Software Group to embed its NTFS for Mac OS software onto every GoFlex drive, and setting it up is as simple as a one-time installation when you first plug it in. From there, the drive will mount on both Macs and PCs with full read and write access without any degradation in speed.
The only catch is that the drive won't work with Time Machine if you're using NTFS for Mac at the same time, since Apple requires all external storage to be HFS+ formatted. Luckily, Seagate gets around that issue by offering its own watered-down backup software through another partnership with software developer Memeo.
