    What is ReadyBoost?
    ReadyBoost is a technology built into Windows Vista that caches disk reads onto a flash memory device. It can work with USB memory keys, flash memory cards, such as SD and CompactFlash, and other types of flash devices. It caches all types of file reads, not just the working set, nor just DLL's or other persistent operating system data.

    ReadyBoost does not cache file writes—it's a write-through cache. That way, you never lose any precious data that's meant to be written to a hard drive. After all, a flash memory key can get yanked out of a system at any time. The cache itself is encrypted using AES-128 encryption, so no one can steal your flash memory key and casually browse through the cache file to see what you've been doing. Continued...

    Jim Allchin demo'd this at the last Summit.
    At the time it added to the global pool for system memory, and did not restrict itself to the read cache.

    It got a fairly luke warm reception from the audience. It would be nice if Microsoft allowed granular controls over the amount of memory given to the disk cache, background, foreground programs, etc. but until this small step they have refused to do so.

    I guess I see it as more a server benefit (Longhorn server), but then my tasks are not very disk read intensive.
