The German computer magazine Winfuture revealed in a recent post that Microsoft will extend Readyboost support in Windows 7. Readyboost was introduced in Windows Vista and was used to add flash drive caches of up to 4 Gigabytes to the system. The main intention of Readyboost was to provide lower end systems running Windows Vista with better performance by utilizing those additional flash caches.
The updated Readyboost in Windows 7 will see several advancements. The 4 Gigabyte restriction will be lifted which essentially means that flash drives with larger capacities can then be used as additional cache. The limit to one Readyboost device has also been removed which gives users the possibility to use multiple flash drives as additional caches in Windows 7.
