Why lug around a USB 2.0 flash drive when you could slip a SuperSpeed USB 3.0 stick onto your keychain? Oh, your PC isn't equipped with a USB 3.0 port? Point taken as we shake an angry fist at Intel and AMD. Still, at some point USB 3.0 ports will become commonplace, so if you're the type that likes to think ahead, a USB drive like Kingston's DataTraveler Ultimate 3.0 Generation 2 (DTU30G2) is about as future proof as you can get at the moment.
The DTU30G2 is Kingston's fastest USB flash drive, no big surprise when you factor in the native USB 3.0 controller. It has a rated read speed of up to 100MB/s and a write speed of up to 70MB/s, assuming you're able to jam it into a USB 3.0 port. If not, the drive will deliver up to 30MB/s read and write speeds via USB 2.0.
Kingston's DTU30G2 is available now in 16GB ($77), 32GB ($116), and 64GB ($213) capacities.
