  • Publication number: 20220404997
    Abstract: A storage system forms an allocation unit for writing into solid-state storage memory. The allocation unit is formed from at least a portion of a first erase block and a first sub block of a partitioned second erase block. The system forms multiple subsequent allocation units. Each subsequent allocation unit is formed from a remaining second sub block of a partitioned erase block and at least a portion of a next erase block. Forming the subsequent allocation units consumes each of multiple erase blocks in a cascading sequence. The system allocates the allocation unit and the subsequent allocation units for writing in the storage system.

  • Patent number: 11520514
    Abstract: A command is transmitted to a storage device to relocate first data that partially fills a first erase block of the storage device and second data that partially fills a second erase block of the storage device to a third erase block of the storage device, wherein the command causes the relocation of the first data and the second data while bypassing sending the data to the storage controller. An acknowledgement that the first data and the second data have been stored at the third erase block is received from the storage device.
