Dynamic partition storage method, device and system of TCL chip solid-state disk

Abstract

The invention provides a dynamic partition storage method, device and system of a TCL chip solid-state disk. When space of the disk is larger than a preset numerical value, a data flow is stored into the disk in the mode that one data is stored into a storage unit; when the space of the disk is smaller than the preset numerical value, the space of the disk is divided into three regions, hot data already stored into the disk is movably stored into one of another two regions in the mode that two data are stored into one storage unit, and cold data already stored into the disk is movably stored into the other one of another two regions in the ode that three data are stored into one storage unit. When the space of the TCL chip solid-state disk is large, rapid reading and writing can be guaranteed for the disk; when the space of the disk is small, the data is moved into different regions according to the using frequency of the data, and the original region is still used for storing rapid data; in this way, while reading and writing speed of the data is considered, normal operation is guaranteed for the disk, and the performance of the TCL disk which is low in cost and large in capacity is greatly improved.

Description

technical field [0001] The invention relates to the field of storage systems, in particular to a dynamic partition storage method, device and system of a TLC chip solid-state hard disk. Background technique [0002] With the continuous development of electronic technology, the requirements for the performance of storage media are getting higher and higher. Flash memory is a representative of new non-volatile storage media. It has the advantages of high read and write speed, low power consumption and shock resistance, and is widely used in embedded In consumer electronic products such as portable devices and mobile terminals. [0003] At present, there are mainly three types of solid state drives: SLC (Single-Level Cell) chip solid state drive, MLC (Multi-Level Cell) chip solid state drive and TLC (Trinary-Level Cell) chip solid state drive. Compared with these three solid state drives, The storage mechanism of TLC chip solid-state hard disk is 3bit / 1cell, with large storage...

Problems solved by technology

[0003] At present, there are mainly three types of solid state drives: SLC (Single-Level Cell) chip solid state drive, MLC (Multi-Level Cell) chip solid state drive and TLC (Trinary-Level Cell) chip solid state drive. Compared with these three solid state drives, The storage mechanism of TLC chip solid-state hard disk is 3bit / 1cell, with large storage capacity, low price but slow speed, which restricts the application of TCL chip solid-state hard disk in high-performance electronic products. If the read and write speed can be improved, it can be greatly reduced. application cost
