Abstract
A cache system for a storage device includes (i) one or more solid state drives (SSDs), (ii) one or more random access memories (RAMs), and (iii) a cache control device. The cache control device caches at least some of first data that is to be written to the storage device, and caches at least some of second data that is retrieved from the storage device. When caching first data or second data in one of the one or more RAMs, the cache control device writes to the one RAM non-sequentially with respect to a memory space of the one RAM. When caching first data or second data in one of the one or more SSDs, the cache control device writes to the one SSD sequentially with respect to a memory space of the one SSD.
