Readyboost drives are traditionally thumbsticks that plug into a USB port. This is a module that straps right onto a motherboard USB header, otherwise used for mounting additional USB ports at the back of the machine, and provides up to 2GB of flash integrated.
The flash should accelerate Windows functions by caching frequently used files and components.
The 2GB model is expecting to go for $70, with a weedy 256MB edition coming in at $23.
