Embodiment Construction

[0036] The technical solution of the storage device and its data management method will be described in detail below in conjunction with specific embodiments and drawings, so as to make it more clear.

[0037] Such as figure 1 As shown, in one embodiment, a data management method of a storage device includes the following steps:

[0038] Step S110, determine whether the write command is a random write command, the write command includes write data and the target write address of the write data, if yes, execute step S120, if not, execute step S130.

[0039] In one embodiment, such as figure 2 As shown, the steps of judging whether the write command is a random write command include:

[0040] Step S210, judging whether the target write address in the write command is continuous with the target write address included in the previous write command, if yes, execute step S220, if not, execute step S230.

[0041] Step S220, determining that the write command is a sequential write...

Abstract

The invention relates to a storage device and a data management method of the storage device. The data management method of the storage device comprises the following steps: whether a writing instruction is a random writing instruction is judged; the writing instruction comprises write-in data and a target write-in address of the write-in data; if the writing instruction is the random writing instruction, the write-in data are sequentially written into a random writing data storage area which is pre-divided from a total storage space, and a corresponding relation of the write-in address of the write-in data in the random writing data storage area and the target write-in address is established; if the writing instruction is not the random writing instruction, the write-in data are written into the target write-in address. According to the storage device and the data management method of the storage device, whether the writing instruction is the random writing instruction is judged; and when the writing instruction is the random writing instruction, the write-in data are sequentially written into the random writing data storage area. Therefore, the addressing time and the waiting time in the process of writing data can be greatly reduced, and the data write-in efficiency of the storage device is improved.

Description

technical field [0001] The invention relates to the storage field, in particular to a storage device and a data management method thereof. Background technique [0002] Storage devices have become a necessity in people's daily life. The data writing speed of a storage device has become an important indicator for measuring the performance of a storage device, especially an SSD (Solid State Disk, solid state drive) product. With the increase of the capacity of the storage device, and because each write needs to be re-addressed and each time the write command is executed, the host needs to wait for the completion of the storage device before sending the next write command. In this way, the write It takes a lot of addressing time to input data for addressing, and it takes a long time to write an instruction, so the efficiency of traditional storage devices is not high when writing data. Contents of the invention [0003] Based on this, it is necessary to provide a data manag...
