ThinkComputers.org posted a review on the Kingston DataTraveler HyperX 4GB USB Drive

Earlier this year Kingston released the DataTraveler HyperX series USB drives which are available in three different capacities: 2GB, 4GB, and 8GB. This is by far the fastest USB drive Kingston has produced with transfer rates of 30mb/s read and 20mb/s write. It not only has fast transfer rates, but fast access times as well. The HyperX is enhanced for Windows ReadyBoost and comes with a 5 year warranty. Read on further to see how well this USB drive puts out.
