Abstract: A storage system performs garbage collection, with data compression, in storage memory. The system obtains hash results from data segments. The system determines similarity of content of data segments, based on the hash results. The system performs data compression of live data of two or more data segments that have similarity of content meeting a similarity threshold. The system writes the compressed live data of the two or more data segments into the storage memory.

Abstract: A storage system includes a central storage controller and a solid-state storage device operatively coupled to the central storage controller, the solid-state storage device including a processing device, the processing device to determine whether a die of the solid-state storage device is likely to fail. In response to determining that the die of the solid-state storage device is likely to fail, the processing device is further to mark the die of the solid-state storage device as likely to fail and transmit, to the central storage controller, an indication that the die of the solid-state storage device has been marked as likely to fail.
