The Patriot Supersonic Boost XT and Rage XT 64GB USB 3.0 Flash Drives are positioned for more than the average user. Both the Boost XT and Rage feature faster speeds and can be purchased in higher than average capacities. The Boost XT is the slower of the two, featuring read speeds up to 90MB/s. However, the Boost XT is built with a hard rubber casing giving it a rugged design. The Boost XT is both water and shock resistant. The Rage was built for speed. This flash drive has been rated with read speeds up to 180MB/s and write speeds of 50MB/s. The Rage uses a capless and thinner design for easier portability. Both come with a 5 year warranty.
