Abstract

The invention discloses a data writing speed determination method and device and computer equipment, and the method comprises the following steps: obtaining a data writing amount within a preset time; when the data writing amount in the preset time is smaller than or equal to a preset flow threshold value, obtaining a residual cache space of a cache; and adjusting the current data writing speed according to the size of the residual cache space. According to the method and the device, the data writing quantity in the preset time is compared with the preset flow threshold value, and when the data writing quantity in the preset time is smaller than or equal to the preset flow threshold value, the current data writing speed is adjusted through the size of the residual space of the cache, so that the long-term stable adjustment of the service cache can be realized, the cache cannot be fully written, and the server is always kept in an available state.

Description

technical field [0001] The present invention relates to the technical field of Blu-ray storage, in particular to a data writing speed determination method, device and computer equipment. Background technique [0002] At present, there are three main ways of domestic data storage: magnetic tape (data stream), hard disk and Blu-ray disc. Among them, the method of using magnetic tape to store data has inherent disadvantages: it is easy to be damp and demagnetized, and the tape is broken; the tape life is short, generally about 10 years, and it can only be eliminated when it expires, and cannot be used; the format and cross-generation are not compatible, and after three to five years For upgrading, the data needs to be copied and copied again, which is equivalent to repeated construction and requires a lot of manpower; therefore, the method of using magnetic tape to store data is being gradually eliminated. The hard disk is not suitable as a long-term storage medium due to its ...
