Abstract
In a data storage system, a data set as compressed by a first compression technique (e.g., a hardware-based compression technique) is stored in non-volatile data storage in association with at least a particular address. In response to a subsequent garbage collection read of the particular address, control logic determines whether or not to compress the data set with a second compression technique (e.g., a software-based compression technique). In response to determining not to compress the data set with the second compression technique, the control logic writes the data set back to the non-volatile data storage as compressed by the first compression technique. In response to determining to compress the data set with the second compression technique, the control logic compresses the data set with the second compression technique and writes the data set back to the non-volatile data storage as compressed by the second compression technique.
