Seagate is still pushing their GoFlex Desk line as hard as they can. After releasing the first 3TB external drive last year, they're raising the bar with their new 4TB beast.
Seagate's GoFlex Desk is the world's first single-drive 3TB external hard disk. It isn't egregiously expensive, even though you have to add in the extra costs of adapters for higher-speed transfers.
This Seagate FreeAgent GoFlex Desk sounds like an exercise commandment for your desk, but it's the world's first 3TB external hard drive. Best news: It has USB 3.0 and FireWire 800 (along with USB 2.0).
