Abstract: A method of operation of a data storage system includes: identifying a target block; configuring a command setting for maximizing a data retention period of the target block for refreshing the target block; writing a pre-archived memory block to the target block based on the command setting; and updating an archive status for sending to a host device.

Abstract: The present disclosure includes systems and techniques relating to non-volatile memory. A described system, for example, includes a non-volatile memory structure having a plurality of multi-level memory cells, a processing device, and a controller. The controller is configured to map a first portion of a first set of consecutive bits of a data segment to a first page associated with the plurality of multi-level memory cells, and map a second portion of the first set of consecutive bits of the data segment to a second page associated with the plurality of multi-level memory cells. The first page is associated with bits of a first significance, and the second page is associated with bits of a second significance.

Abstract: A machine implemented method and system for allocating a storage volume from among a plurality of storage volumes for storing information in a storage system is provided. The storage system maintains a plurality of groups for segregating the plurality of storage volumes based on storage volume utilization at any given time. A storage volume, when available, is selected from a group that was previously used to select another storage volume. After an end of the group has been reached for allocating the other storage volume, and a threshold value for using the same group to allocate storage volumes has been reached, then another group is used to select the next storage volume.
