Seagate's portable hard drives, with mix-and-match detachable interfaces, have been with us for some time now. The whole idea is that you should only need one hard drive, and then you can change the interface depending on what your need is — USB, Firewire 800, eSATA — but, of course, only once you've shelled out between AU$30 and AU$50 extra for that Seagate-branded attachment in the first place.
You can pick up the FreeAgent GoFlex Ultra Portable with either the USB 2.0 or USB 3.0 flavour by default, with the USB 2.0 version coming in capacities of 320GB to 1TB, and USB 3.0 wielding 500GB to 1.5TB. If you're particularly fussed about colour, it's available in black, red, grey or blue.
We tested performance under CrystalDiskMark, and, while it's still a mechanical drive, we found the USB 3.0 interface to provide quite a decent boost over its predecessor.
