Problems solved by technology

However, because it is impossible to predict the time point when the master device requires access to data, the storage optimization process may be interrupted and the expected effect cannot be achieved

Abstract

An embodiment of the present invention provides a method for accessing a solid-state hard disk, and the method is implemented by a processing unit when a driving program is loaded and executed. The method includes the following steps of determining one from first and second IO queues, moving an earliest access command out of the determined IO queue, and generating a data access request containinga physical location according to the access command which is moved out and sending the data access request to a solid-state disk. The first IO queue stores a plurality of general access commands issued by an application, and the second IO queue stores a plurality of access optimization commands.

Description

technical field [0001] The present invention relates to a storage device, in particular to a solid state disk access method and a device using the method. Background technique [0002] A NAND flash device is usually provided in a solid-state hard disk. NAND flash devices do not have random access, but sequential access. The NAND flash device cannot access any random address like the NOR flash device. Instead, the master device needs to write the value of the sequence bytes (bytes) into the NAND flash device, and define the type of the request command (command) ( eg, read, write, erase, etc.), and the address used on this command. The address can point to a page (the smallest data block of a write operation in flash memory) or a block (the smallest data block of an erase operation in flash memory). Generally, in order to effectively utilize the storage space in the solid-state disk, the processing unit in the solid-state disk needs to execute some storage optimization prog...
