EFFICIENT FTL IMPLEMENTATION WITH COMPRESSION

A method for accessing a block of information stored in a SSD memory, the method may include obtaining, by an SSD controller, an identifier associated with the block of information; accessing, using the identifier, a first data structure that maps identifiers to cluster maps; wherein the first data structure comprises block sequence metadata, wherein for at least one cluster map, the block sequence metadata comprises a sequence identifier of a sequence of blocks of information that are sequentially written to the SSD memory and are stored together in a cluster of the SSD memory; accessing a cluster map of a cluster that is associated with the sequence provide block retrieval information; and retrieving the block of information from the SSD memory, using the block retrieval information.
