http://thunderbolt-hard-drive.com/ – The cheapest ThunderBolt hard drive to date – the Buffalo miniStation portable laptop drive is one of the first to offer both ThunderBolt AND SuperSpeed USB interfaces at a very low price. In addition to the SuperSpeed USB 3 cable, it also includes a ThunderBolt cable in the box – which is otherwise a separate $50 expense with most other ThunderBolt backup drives.
This ThunderBolt portable hard drive is available in both 500GB and 1TB sizes starting around $200 making it the most affordable high-speed backup drive for Mac. However, because of the mechanical laptop drive SATA mechanism inside, it’s true data transfer speed potential is terribly bottle-necked. After a drive take-apart, I’ll be upgrading the spinning platter mechanism to a solid-state flash memory based SanDisk Extreme SSD to truly leverage the available bandwidth of ThunderBolt or USB 3.0 interfaces.
The miniStation is pre-formatted for Mac OSX and Apple TimeMachine use, ready to go out of the box. Note that USB 3.0 drives are backward compatible with USB 2.0 as well – at slower speeds. It can also be reformatted for Windows NTFS if need be. Lastly, Buffalo’s backup drive has a 3-year warranty.
