Abstract

The invention discloses a storage device and a data processing method thereof. The storage device comprises a first storage unit and a second storage unit. The method comprises the following steps: detecting a random writing performance parameter of the storage device; writing the to-be-stored data into the second storage unit according to a first strategy when the random writing performance parameter of the storage device is less than or equal to a preset threshold value; and writing the data in the second storage unit into the first storage unit according to a second strategy, wherein the random writing performance parameter of the second storage unit is more than the random writing performance parameter of the first storage unit.

Description

technical field [0001] The invention relates to data storage technology, in particular to a storage device and a data processing method thereof. Background technique [0002] Solid State Drives (SSD, Solid State Drives) are referred to as solid disks for short, and SSDs are composed of a controller and a storage unit. NAND flash memory is a non-volatile storage technology, that is, it can still save data after power failure. Usually, the storage unit in SSD is composed of NAND flash memory particles. [0003] In the initial stage of SSD use (typically when the entire disk has not been sequentially written twice), the random write performance often drops by more than half, or even drops to one-tenth, which greatly affects the customer experience. This is because the wear leveling of NAND has not been done well. To make the wear leveling mechanism work well, it is necessary to write 2 times or more on the whole disk. However, as the SSD capacity becomes larger and larger, fr...
