Abstract: A caching system and methodology for data in a memory for faster access to commonly-used data by other applications and computer devices on a network. The memory can include a solid-state drive (SSD) array for the cache memory that has read-bias, in addition to a magnetic hard drive array. The system uses a logical set of slots to hold identifiers for specific groups of data that can be placed into cache memory and each identifier has a usage attribute that changes based upon the usage of the specific group of data and causes the identifier to move within the set of slots and potentially into cache memory.
