Abstract
The present invention is a system and method for utilizing shadow/ghost list to prevent excessive wear on FLASH based cache devices. The method determines when data is highly likely to be accessed again, and avoids writes to a FLASH based caching device when data is unlikely to be accessed again through the use of 'shadow' or 'ghost' lists that are also used to perform adaptive caching.
