Problems solved by technology
[0003] Nowadays, in the application of solid-state disks, the use of technologies such as multi-core processors on the host side makes the host side have more and more powerful resources. However, the resources of the solid-state disk on the device side are relatively insufficient, which will cause the performance of the solid-state disk to decline. At the same time, it will affect the user experience

The invention discloses a collaboration-based solid-state disc memory system performance improving method. The method comprises the following steps: dividing data blocks into a hot data block and a cold data block, collecting garbage recycling information, transferring the garbage recycling information to a solid-state drive at equipment terminal, wherein the solid-state drive is used for receiving the garbage recycling information and executing the garbage recycling operation. The performance of the solid-state drive memory system is improved through the adoption of the collaborative garbage recycling of a host terminal and the equipment terminal.
Description
technical field [0001] The invention belongs to the technical field of computer data storage, and more particularly relates to a method for improving the performance of a solid-state disk storage system based on cooperation. Background technique [0002] A Solid State Drive (SSD for short) is a hard disk made of an array of solid-state electronic storage chips. The current solid-state drives are mainly based on FLASH chips. With the reduction of the cost of solid-state disks, solid-state disk storage systems have been widely used in automotive, video surveillance, military, network terminals, electric power, medical and other fields. [0003] Nowadays, in the application of solid-state disks, the use of technologies such as multi-core processors on the host side makes the host side have more and more powerful resources. However, the resources of the solid-state disk on the device side are relatively insufficient, which will cause the performance of the solid-state disk to de...
