The Seagate have connectors that are removable. For example, you can get a USB 2.0 connector with a GoFlex drive, and if you decide later that you want FireWire 800, you can buy the FireWire 800 connector, remove the USB 2.0 connector, and replace it with the new FireWire 800 connector.

Back in February, Seagate for its GoFlex drives. And though it has yet to ship, it did make an appearance at IDF (or at least the outer casing of the adapter made an appearance).

Also displayed was a black box generically labeled, "Seagate Desktop Storage," which seems to indicate that Seagate plans to implement Thunderbolt in its desktop hard drives.

Thunderbolt is based on the PCI Express (PCIe) architecture, and you might know that the Mac Pro has four PCIe slots. That means there are a slew of PCIe expansion cards available--you can use them on Thunderbolt iMacs, Mac minis, MacBook Pros, and MacBook Airs through an adapter box.
