Abstract

Provided are a data write-in method, apparatus and device, and a storage system. The method comprises: an NVM controller receiving a first atomic write request sent by a central processing unit; the NVM controller storing data corresponding to the first atomic write request and an address which is to be written and corresponds to the first atomic write request into a write request memory; the NVM controller performing conflict detection on the first atomic write request, so as to determine at least one first write operation concurrence group in the first atomic write request and determine a first sequence for writing data corresponding to various first write operation concurrence groups in the first atomic write request into an NVM medium; and according to the first sequence and the address which is to be written and corresponds to the first atomic write request, the NVM controller writing the data corresponding to various first write operation concurrence groups in the first atomic write request from the write request memory into the NVM medium. By means of the method provided in the present invention, the data writing efficiency is improved, and the costs for ensuring the uniformity of a file system are saved.
