Seagate GoFlex – the biggest external HDD

It’s been a little over a year since Seagate Technology announced the FreeAgent GoFlex Desk, which offered up to 3TB of storage, and today, the company once again broke the storage barrier by introducing its first 4TB single-volume external hard drive, the 4TB GoFlex Desk.

The stock model ships with USB 2.0 / 3.0 support and support for OS X and Windows platforms. The entire unit weighs but 2.38 pounds and checks in at 6.22- x 4.88- x 1.73-inches.

USB 3.0 burst rates top 100MB/sec, while sustained transfers hovered closer to 60MB/sec. When used on a USB 2.0 rig, we saw reads and writes hover between 30MB/sec and 40MB/sec.
