The invention provides a nonvolatile storage medium data processing method and a nonvolatile storage medium in the technical field of storage. The method comprises the steps of obtaining a first operation parameter value of a storage unit; wherein the first operation parameter value represents data read-write performance of the storage unit; when the first operation parameter value meets a recovery condition, recovering the valid data page in a failure data block; and not recovering the valid data page when the first operation parameter value does not meet the recovery condition; when the recovery of the valid data page is executed and the recovery condition is not met, pausing the recovery of the valid data page or not performing the recovery of the valid data page is not carried out, sothat the bus bandwidth is provided for data reading and writing, and data reading and writing efficiency is improved.
