Readyboost is a new disk caching technique in Windows Vista which uses flash memory from flash devices to boost system performance. Caching system resources for small, random I/Os in flash ram is faster than caching them on one of your hard drives which speeds up certain disk reads by the factor 8-10.
It is pretty easy to enable Readyboost in Vista. Plug in your usb stick or flash device and wait for the autostart menu. Select Speed up my System using Windows Readyboost from the menu. Windows Vista will perform some tests and display information if the device is not compatible with Readyboost. After that is done Readyboost is activated and Windows Vista uses the additional free space to speed up some disk reads.
The devices have to meet some requirements like having a size between 256 MB and 4 GB. Other requirements are USB 2.0 support, at least 64 Mb of free space and 3.5 MB/s read speeds for 4 kB random reads spread uniformly across the entire device and 2.5 MB/s write speeds for 512 kB random writes spread uniformly across the device.
This is a great way to improve performance without adding new ram to the system. It is definitely not the best way to improve the performance of Vista but a good method to achieve better results fast. If you have the choice to buy more ram do that, if you canÂ’t do that use the flash device instead.
