[0080] refer to figure 2 , the first embodiment of the storage device management method of the present invention, the storage device management method includes:
[0081] Step S10, acquiring the target block in the storage device;
[0082] In this embodiment, the storage device can be a U disk (full name USB flash drive, English name "USB flashdisk"), SD card (SD memory card is a new generation memory device based on semiconductor flash memory), EMMC (EmbeddedMulti Media Card), SSD (Solid State Drives, solid state drive), UFS (Universal FlashStorage), etc.; block (Block) as the smallest erasing unit of storage devices, each block includes several pages (Page), and pages are used as storage The minimum reading and writing unit of the device, each page includes several bytes (Byte), and each byte is composed of several bits (such as 8bit, 16bit). When data is written to the page each time, the block needs to be erased first, and each block is erased a certain number of times, ...

The invention discloses a storage device management method, device and computer-readable storage medium. Wherein, the storage device management method includes the following steps: obtaining a target block in the storage device; obtaining a plurality of read and write parameters of the target block, and obtaining the optimal value of the target block from the plurality of read and write parameters. Read and write parameters; judge whether the target block is an available block according to the optimal read and write parameters; if the target block is an available block, store the available block in association with the optimal read and write parameters, and call The optimal read and write parameters perform read and write operations on the available blocks. The invention has the advantages of improving the reading and writing speed of the storage device and prolonging the service life of the storage device.
Description
technical field [0001] The invention relates to the technical field of data storage, in particular to a storage device management method, device and readable storage medium. Background technique [0002] In the prior art, when most of the blocks in the storage device are about to reach the maximum number of erasing times or the error is large, the storage device enters the late-life state; while the read and write parameters are pre-written by the manufacturer, basically no It will change, however, with changes in usage environment factors, these fixed read and write parameters will lead to a large number of error correction, decoding and other processes during the read and write time of the storage device entering the late life state, resulting in a decrease in the read and write speed of the storage device; At the same time, when the storage device cannot read data correctly according to the pre-written read and write parameters, the storage device will be judged as scrapp...
