Readyboost Compatibility List

ReadyBoost is a feature, first introdcued in Windows Vista but also present in Windows 7 and Windows 8, that improves system performance by utilising the capacity of an unused flash memory device, for example a USB stick or SD card.

However, not all flash devices are fast enough to work with ReadyBoost. Below you’ll find lists, organised by brand, showing which devices are compatible (and incompatible) with ReadyBoost. These lists were compiled based on data supplied by readers – thank you all!
