Abstract
The present disclosure generally relates to data storage devices, such as solid state drives. The data storage device includes a controller that includes a compression engine. The controller receives a ZNS append command to write data to a media, such as a non-volatile memory. The compression engine compresses data from a first number of logical blocks to second number of logical blocks. The compressed data is programmed to the media. The compressed data has a media logical block address and a host logical block address, where the media logical block address is the actual LBA where the ZNS append places the data on the media and the host logical block address is the location of the data stored on the media from the host's point of view. The host generates an index of the location of the stored data and the controller programs the index to the relevant location in the media.
