. That depends on how much RAM you have on your system. The smallest cache that ReadyBoost can use is 256MB; the largest is 4GB. Microsoft recommends establishing a flash-memory-to-system-RAM ratio of anywhere from 1:1 to 2.5:1. For a system containing 512MB of RAM, it follows that 512MB to 1.25GB of flash memory will be productive. Since ReadyBoost maxes out at 4GB, any amount of flash memory beyond that ceiling won’t provide a boost, regardless of your PC’s quantity of RAM.
