Abstract

The embodiment of the invention relates to a data migration method and a data migration device of a solid state disk and the solid state disk. The data migration method comprises the following steps: reading first data of a first data block in a solid state storage unit in a data register of the storage unit, and naming the first data of the data register with read-in data as second data; checking and correcting the second data; and writing the checked and corrected second data in a second data block of the storage unit. The embodiment of the invention improves the efficiency of data migration, reduces the time of the data migration and improves the data rate of the data migration.

Description

technical field [0001] The invention relates to computer technology, in particular to a data migration method for a solid-state hard disk, a data migration device and a solid-state hard disk. Background technique [0002] Solid State Disk (Solid State Disk; hereinafter referred to as: SSD), as a new generation of fast storage devices, is usually made into notebook hard drives, micro hard drives, memory cards or USB flash drives, etc. SSDs usually use flash chips as storage media. In the process of operating the data stored in the SSD, it is usually necessary to move the data stored in the flash chip from one data block inside the chip to another data block. [0003] In an existing data migration method for a solid state disk, the SSD uses a copyback command to perform data migration. When the migrated data needs to be read, an error correction code (Error Correction Code, hereinafter referred to as: EEC) module in the SSD is used to correct the errors of the data. Due to t...
