Solid state disk and data processing method and system thereof

Abstract

The invention is applied to the technical field of storage, and provides a solid state disk and a data processing method and system thereof. The data processing method of the solid state disk comprises the following steps: dividing a plurality of flash memory channels into at least two flash memory channel groups, and each flash memory channel corresponds to a flash memory chipset; each flash memory channel group is respectively provided with a different logical physical management array and a different redundancy, the redundancy relates to an excessive part of a physical capacity of flash memory medium in the flash memory channel group according to a logical capacity of the flash memory channel group; storing high read and write performance and frequency requirements data to the flash memory chip corresponding to the high-redundancy flash memory channel group; storing low read and write performance and frequency requirements data to the flash memory chip corresponding to the low-redundancy flash memory channel group. Therefore, the solid state disk and the data processing method and system of the solid state disk enable the solid state disk to be capable of providing a higher capacity and having better performance and longer service life, and achieve the balance of the flash memory capacity, the performance and the service life.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a solid-state hard disk and a data processing method and system thereof. Background technique [0002] NAND flash-based SSDs have become the storage solution for many different applications ranging from consumer electronics to high-end enterprise systems. Compared with the traditional hard disk, it has the advantages of fast access speed, low power consumption, high reliability, good shock resistance, small size and non-volatile. In addition, the price per byte of flash memory is gradually decreasing, which means that traditional hard drives will be replaced by solid-state drives in the near future. [0003] like figure 1 As shown, currently a large-capacity SSD generally includes multiple channels (channels), and multiple flash memory chips are mounted on each channel (such as figure 1 4 flash chips shown). In the traditional FTL (flash translate level, flash translation la...

Problems solved by technology

However, in actual business, data is generally hot or cold, that is, some data will be read and written frequently, while others will not. Frequently written data will affect the performance and lifespan of the storage medium.

[0005] In summary, the existing solid-state hard drives and their data processing methods obviously have inconveniences and defects in actual use, so it is necessary to improve them.
