  • Data migration method, host, and solid state disk
    Patent number: 11960749
    Abstract: A host of a storage system is coupled to multiple SSDs. Each SSD is configured with a migration cache, and each SSD corresponds to one piece of access information. The host obtains migration data information of to-be-migrated data in a source SSD, determines a target SSD, and sends a read instruction carrying information about to-be-migrated data and the target SSD to the source SSD. The source SSD reads a data block according to the read instruction from a flash memory of the source SSD into a migration cache of the target SSD. After a read instruction is completed by the SSD, the host sends a write instruction to the target SSD to instruct the target SSD to write the data block in the cache of the target SSD to a flash memory of the target SSD.

  • Method and apparatus for managing health of a storage medium in a storage device
    Patent number: 10901629
    Abstract: A method for managing a storage medium in a storage device is provided. The method includes detecting whether there is a problematic storage block in a data storage area of the storage medium, wherein the problematic storage block is a storage block whose health degree is less than a preset value, wherein the health degree is used to measure performance of a storage block in the storage medium and is in direct proportion to the performance of the storage block; and replacing the problematic storage block with a replacement storage block in a replacement area of the storage medium when the problematic storage block is detected, wherein a health degree of a storage block in the data storage area is greater than a health degree of a storage block in the replacement area.
