At the recently concluded Computex 2013, Intel showed off its prototype 128GB Thunderbolt thumb drive. The company claimed it is the world's fastest thumb drive.
Besides boasting of Thunderbolt connectivity, the thumb drive uses a SanDisk SSD for storage; however, according to MacRumors, this may change when the thumb drive goes into final production. The drive is convenient to use as it doesn't require an additional Thunderbolt cable. Thunderbolt has transfers speeds of up to 10Gbps, making it, possibly the fastest thumb drive in the world now. Most thumb drives feature the USB 3.0 interface, and its transfer speed is up to 5Gbps that is half of Thunderbolt's.
In April this year, Intel announced Thunderbolt 2, the next generation of Thunderbolt that will feature transfer speeds of up to of 20Gbps. Besides being faster, Thunderbolt 2 is touted as being able to support 4K displays while handling data transfer. It is slated for release in 2014.
