Crucial and Lexar together put out a pair of high-speed storage options ahead of CES. Topping the two is a special 50GB Adrenaline version of Crucial's m4 SSD intended as a cache for an existing drive. While it doesn't have to be used that way, the combination of a 2.5-to-3.5-inch adapter bracket and special software turns the SATA drive into a buffer for frequently accessed files on a larger hard drive, speeding up the OS and apps without having to sacrifice space.
