Abstract

Techniques for data writing involve: determining an unavailable storage zone in multiple storage zones of a storage area, wherein each storage zone is used to store a zip header and compressed data corresponding to the zip header; acquiring a reference zip header for the unavailable storage zone, wherein the reference zip header includes metadata indicating a zone length of the unavailable storage zone; and generating consecutive write requests for the storage area based at least on target data to be written to the storage area and the reference zip header, so as to write the target data to available storage zones in the multiple storage zones. Accordingly, rewriting of data can be implemented by constructing large consecutive write requests, thus improving the write performance of the storage device.
