Running out of memory on Vista? Did you know Windows ReadyBoost is a technology which is built into Windows Vista that caches disk reads onto a flash memory device. It can work with USB memory keys, flash memory cards like an SD card or and compact flash card. Most any type of flash media device will work. ReadyBoost caches all types of file reads, not just the working set, nor just DLL’s or other persistent operating system data. While ReadyBoost is not the long-term recommendation for memory issues, it can help you run smoother when you are in a memory jam. Microsoft’s general recommendation for maximum benefit from ReadyBoost is to match the capacity of the flash device to the size of your system’s main memory. So if you have 2GB of system RAM, use a 2GB USB key. Note that some benefit is gained from using any flash device, and the capacities supported for ReadyBoost range from 256MB to 4GB.
