摘要
A method and system for facilitating fast atomic write operations. The system receives a request to write data to a shingled magnetic recording drive (302). The system selects a zone of the drive to which to write the data, wherein the drive stores a previous write pointer indicating a location of an end of a most recent successful write operation in a respective zone (304). The system writes the data at a location of a current write pointer of the selected zone (306). In response to successfully writing the data to the selected zone, the system sets a previous write pointer of the selected zone to a location of an end of the successful write operation (310). In response to not successfully writing the data to the selected zone, the system sets the current write pointer of the selected zone to a location indicated by the previous write pointer of the selected zone (314).
