Embodiment 2

[0057] see figure 2 , Embodiment 2 specifically includes the following steps:

[0058] S21. Write part of the data to any block of the solid state disk to ensure that the block is not filled, and record the writing time.

[0059] S22. Under the working temperature, periodically read the data on the block, determine the data error rate, until the data error rate exceeds the ECC error correction capability, and determine the difference between the current time and the writing time as the time threshold.

[0060] S23. Using the time threshold as a reference time threshold, and according to the reference time threshold and the block number, respectively determine the time thresholds of each block in the solid state disk.

[0061] Specifically, according to the target formula, according to the reference time threshold and the block number, respectively determine the time threshold of each block in the solid-state disk, the target formula is as follows:

[0062] time = open_block...

Abstract

The invention discloses a solid state disk open block processing method, which is characterized in that when an open block is processed, the open block is not filled with junk data, but is subjected to junk collection, the bandwidth is not occupied due to the fact that the junk data is not filled, the read-write performance of a user is not influenced, the processing flow does not need to be increased, the open block processing flow is simplified, the software complexity is reduced, and the reliability of the solid-state disk is improved. In addition, the invention further provides a solid state disk open block processing device and equipment, and the technical effects of the solid state disk open block processing device and equipment correspond to the technical effects of the method.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a solid state disk open block processing method, device and equipment. Background technique [0002] SSDs need to process the open block, that is, the block that is not filled. The previous processing method is to fill in garbage data to the open block. Filling in garbage data means writing invalid data on the Nand, which occupies the Nand bandwidth and may affect users. Write performance leads to slower data writing by users, and a processing flow is added to the implementation, which is more complicated. [0003] It can be seen that how to provide an open block processing solution to avoid affecting the user's read and write performance and increase the processing flow is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of this application is to provide a solid-state hard disk open block processing method,...
