一种进行数据存储的方法、装置及系统
摘要：
本发明涉及电子技术领域，尤其涉及一种进行数据存储的方法、装置及系统，用以解决存储设备写性能较低、使用寿命较短的问题。本发明实施例提供的进行数据存储的方法包括：存储控制器接收待存储数据，存储控制器中设有第一缓存和第二缓存，第一缓存用于缓存第一类数据，第二缓存用于缓存第二类数据，第一类数据的更新频率大于第二类数据的更新频率；存储控制器识别待存储数据中的第一类数据，并将识别的所述第一类数据写入第一缓存中；若写入的第一类数据中包含更新数据，则将第一缓存中该更新数据对应的更新前的数据设为无效；存储控制器在确定当前满足第一类数据的写入触发条件时，将第一缓存中的有效数据写入存储介质。
摘要（英）：

A data storage method, device and system relate to a technical field of electronics and are for solving the problems of low write performance and a short life span of storage devices. The method comprises: a storage controller receives data to be stored, the storage controller being provided with a first cache and a second cache, the first cache being used for caching a first type of data, a second cache being used for caching a second type of data, and an updating frequency of the first type of data is greater than an updating frequency of the second type of data (S201); the storage controller identifies the first type of data in the data to be stored, and writes the identified first type of data into the first cache; if the written first type of data comprises update data, then setting the to-be-updated data corresponding to the update data in the first cache as invalid (S202); the storage controller writes valid data in the first cache into the storage medium when a writing trigger condition of the first type of data is determined as being currently satisfied(S203).
