This application relates to the field of storage technology and discloses a method for protecting partial space of SSD and a storage system. The storage space of the SSD is divided into multiple regions and there is a partition table stored in the SSD, which includes region type of each region. The method includes: receiving, by the SSD, a command to read the partition table; and retrieving, by the SSD, the partition table, removing one or more regions with the region type being locked from the partition table, and returning the removed partition table. This application provides a simple implementation and self-encrypting protection scheme, which requires fewer running resources, is easy to operate, has strong portability, and can meet basic self-encrypting and locking requirements.

Systems, apparatus and methods are provided for logical-to-physical (L2P) address translation. A method may comprise receiving a request for a first logical data address (LDA), and calculating a first translation data unit (TDU) index for a first TDU. The first TDU may contain a L2P entry for the first LDA. The method may further comprise searching a cache of lookup directory entries of recently accessed TDUs using the first TDU index, determining that there is a cache miss, generating and storing an outstanding request for the lookup directory entry for the first TDU in a miss buffer, retrieving the lookup directory entry for the first TDU from an in-memory lookup directory, determining that the lookup directory entry for the first TDU is not valid, reserve a TDU space for the first TDU in a memory and generating a load request for the first TDU.

The present disclosure relates to a data storage device, system, and a data writing method. The device comprises a controller and a plurality of storage blocks, each storage block consisting of an idle storage block and a non-idle storage block, the controller connecting to each storage block respectively, wherein the controller is configured to generate, when receiving a data writing command, a self-adapting adjustment instruction according to a comparison between a storage distribution state of the storage block and a first threshold value to configure the idle-storage block as an SLC block or an XLC block; the storage block is configured to correspondingly adjust the storage distribution state according to the self-adapting adjustment instruction to store written data in the SLC block or the XLC block of the idle storage block. By dynamically configuring the storage blocks as an SLC block or an XLC block according to the storage distribution state, the data storage device, system, and the data writing method according to the embodiments of the present disclosure is capable of maintaining the reading/writing performance of the storage device for a relatively long period.

Data storage device, system, and data writing method

The present disclosure relates to a method for data writing, a device and a storage medium, wherein the method includes acquiring a first data to be written and saving a plurality of sub-blocks of the first data in one or more designated aggregated queue of multiple aggregated queues according to an aggregation strategy; performing, in each designated aggregated queue, data interception on a plurality of sub-blocks in a current queue to obtain a second data to be written; and writing the second data in a storage device. The data distribution written in the storage device becomes more ideal by a multi-queue aggregation, and thus the method for data writing according to the embodiments of the present disclosure can reduce the time consumed in reading the storage device effectively.
