FancyCache for Volume is a handy and reliable application designed to cooperate with system memory to provide data caching for volumes.

It improves system performance by transparently storing data into memory such that future requests for that data can be served faster. FancyCache caches data on a logical block basis (offsets within a volume/disk) while windows cache manager caches on a virtual block basis (offsets within a file).

One of the FancyCache's core components is a storage class filter driver which resides in the storage stack, intercepting I/O requests for data on volume/disk. If requested data is contained in the cache, this request can be served by simply reading the cache, which is comparably faster. Otherwise the data has to be fetched from volume/disk. Hence, the more requests can be served from the cache the better the overall system performance is.

· Supports volume/disk with proprietary file system

Why FancyCache?
Why do we need another cache scheme since Windows OS has already implemented a file-system level cache?

Some applications bypass the file-system level cache.
Windows caches all data, while FancyCache can cache on behalf of a specified volume/disk in which users are interested. Given same size of system memory, the latter has a higher hit-rate.
FancyCache can utilize the OS Invisible Memory on 32-bit Windows as a cache medium.
FancyCache can utilize SSD (Solid-state Drive) as a cache medium, as ReadyBoost does.
