Good news for secret agents and anyone else who has a need to keep their data both portable and secure - Corsair has gone and doubled up the capacity of its Flash Padlock 2 USB thumb drive to 16GB.

Previously only available in 8GB, the Flash Padlock 2 sports a couple of security safeguards, including a user-defined PIN. A user's PIN can range from four to ten digits, while the data inside remains scrambled with 256-bit AES encryption. It should also be noted that the PIN is hardwired to the drive, so there's no special software to install, allowing you to unlock the drive on any USB-equipped PC, be it Windows, OS X, Linux, and even game consoles.

Corsair didn't say when the 16GB version would be available or for how much, though we'd guess it to command around $100. For reference, the 8GB version sells for around $55 street.

All of a sudden we feel woefully inadequate waving around our 16GB and 32GB thumb drives. That's because Corsair on Thursday launched what it claims is the the world's fastest high capacity USB flash drive, the 128GB Flash Voyager GT.

"High performance is a key requirement for super-high capacity flash drives, such as the 128GB Voyager GT, simply because it is able to store such a large volume of data," said John Beekley, the VP of Applications at Corsair. "The 128GB Voyager GT is nearly twice as fast as other high-capacity flash drives, which means less time waiting for your music, video, or office files to copy to and from the drive."

According to Corsair, the MLC-based drive can hit read speeds of up to 32MB/s and write speeds of up to 25.6MB/s thanks to the Voyager's dual-controller architecture. The company also says you're more likely to run into bottlenecks with your USB 2.0 bus or OS system overhead before the drive loses its pep.

All that speed and capacity doesn't come cheap, however. The 128GB Voyager GT is available now with a street price of around $400.
