Most of us don't worry too much about the few seconds it takes to transfer a bunch of files between a flash memory stick and a computer, but if those extra seconds could lead to problems, Intel has a solution for you.
Instead of the more common USB port, the new Thunderbolt thumb drive takes advantage of the extra speed available from your computer's Thunderbolt port. At 10 gigabits per second, this port has about twice the throughput of even the latest USB 3.0 ports, allowing you to transfer your stuff in half the time. The drive will also be able to keep up when the 20 Gbit/s Thunderbolt 2 arrives later this year.
Intel developed Thunderbolt in collaboration with Apple, so it only makes sense that they want to promote their own interface with a product like this. The catch is that apart from Apple's own MacBooks, you don't see Thunderbolt ports on a lot of laptops.
Why you need to shave off every second while transferring files isn't clear to me, but I suppose if you're Bradley Manning trying to upload government secrets to Wikileaks, or some guy trying to hide your porn collection as your partner comes in the door, every second could count.
Intel didn't offer a date when the Thunderbolt drive will become available.
