Abstract

The invention discloses a data storage method, a data storage system and a computer readable storage medium. The data storage method comprises the following steps: distributing a plurality of storagedevices with different performances for equipment in advance; in the running process of the equipment, storing data required to be stored in the equipment into each data block of the storage device; after the equipment starts to run, dividing each data block into data blocks with different popularity levels at preset running time intervals according to the access condition of each data block in the period; according to a one-to-one correspondence relationship between the popularity levels of the data blocks and the performance levels of the storage devices, migrating data stored in the data blocks to the corresponding storage devices according to the popularity levels to which the data blocks belong, wherein the performance of the storage device corresponding to the data block with the higher popularity level is greater than that of the storage device corresponding to the data block with the lower popularity level. Therefore, the cost of the storage device in the equipment is low, andthe storage device with excellent performance is utilized more reasonably.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a data storage method, system and computer-readable storage medium. Background technique [0002] With the development of big data, the amount of data stored on various devices and the average read and write capacity of data are increasing, making the number of storage devices required on the device also increasing. In the prior art, since an SSD (Solid State Disk, solid state disk) has better storage performance, the storage device required on the device is usually selected as an SSD. However, the price of the SSD is relatively high (generally speaking, the performance of the storage device is directly proportional to the price), and for some data that is not frequently accessed, it is wasteful for these data to occupy the SSD. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at prese...
