| The Bottom Line | Even with the slightly low USB 3.0 performance, the GoFlex Ultra still makes an excellent portable external hard drive for people who need to expand their computer's storage. | Though other external hard drives offer a preset menu of ports, the Seagate FreeAgent GoFlex cuts costs by letting you pick from a buffet of "personality cables" so that you buy only the connections that suit your system profile. We applaud Seagate for making data backups easier than ever, and recommend the FreeAgent GoFlex external hard drive for extra data storage now and easy upgrades in the future. | Basic specs | ||
