Abstract
A storage system and method for fast lookup in a table-caching database are provided. In one embodiment, a storage system is provided comprising a volatile memory, a non-volatile memory, and a controller. The controller is configured to store, in the volatile memory, a data structure representing a compressed version of a logical-to-physical address table stored in the non-volatile memory; and search the data structure for a physical address associated with a logical address, wherein the controller is configured to find any physical address in the data structure in a fixed amount of time. Other embodiments are provided.
