Abstract: Methods and systems for wear-leveling in flash storage devices are provided. A flash storage system performs wear-leveling by tracking data errors that occur when dynamic data is read from a first storage block in a first flash storage device and moving the dynamic data to a second storage block in a second flash storage device. Additionally, wear-leveling is achieved by identifying a third storage block containing static data and moves the static data to the storage block previously containing the dynamic data.

Abstract: A flash storage system includes a data buffer configured to receive and store a data block having data portions. The system further includes flash storage devices having storage blocks interleaved among the flash storage devices and a controller coupled to the data buffer and the flash storage devices. The controller is configured to initiate data transfers for writing the data portions of the data block asynchronously into the storage blocks, where the data transfers for writing the data portions of the data block asynchronously into the storage blocks include reading the data portions of the data block from the data buffer serially and writing the data portions of the data block into the storage blocks in parallel.

Abstract: Aspects of the subject technology relate to a data storage system controller including a host interface configured to be coupled to a host device, to receive data from the host device, and to send data to the host device. In certain aspects, the data storage system includes a primary compression engine configured to compress data received from the host device via the host interface, and a secondary compression engine configured to decompress and compress data associated with operations internal to the data storage system. In some implementations, the data storage systems can further include a processor configured to transfer data between the host interface and the primary compression engine, between the primary compression engine and a non-volatile storage medium, between a memory and the secondary compression engine, and between the secondary compression engine and the memory. A data storage system is also provided.
