PureOverclock published a review of the Kingston DataTraveler 64GB USB flash drive.

Today we're looking at the Kingston DataTraveler 64GB flash drive, and to prove or dispel the notion that high capacity drives are slow, we're going to pit it against a popular and fast, smaller capacity flash drive. Inspired by Newton's proof that heavier objects do not fall faster to the ground than lighter ones, we're not convinced that large capacity flash drives transfer files slower than smaller drives. So we put it to the test, and we think you may be quite surprised with the results.
