Seagate FreeAgent GoFlex Ultra-Portable
Budget external hard drive
If your budget is tight, and you don't need quite as much external storage, experts point to the 320 GB Seagate FreeAgent GoFlex Ultra-Portable as an excellent choice. Reviews praise its speed, simple design and backup software, and the way it's friendly to households with Macs and PCs; it'll work on both without reformatting. In addition to being very portable, the drive is very flexible. Though natively equipped with only a USB 2.0 connection, you can upgrade at any time to a faster port (USB 3.0, eSATA, FireWire) with the purchase of a $20 adapter. It also works with a number of other Seagate accessories for converting into a home media server and other uses. If you want the features of the FreeAgent GoFlex Ultra-Portable but need more storage, capacities up to 1 TB are available.
