Automatic deletion in persistent storage devices

A system and method for automatic deletion in a persistent storage device. In some embodiments, the method includes: receiving, by a persistent storage device, a first read command for a first logical data block; determining that a total number of read operations for the first logical data block is equal to or exceeds a first threshold; in response to determining that the total number of read operations for the first logical data block is equal to or exceeds the first threshold, deletion of the first logical data block from the persistent storage device is arranged. 一种用于在持久性存储设备中自动删除的系统和方法。在一些实施例中，该方法包括：由持久性存储设备接收针对第一逻辑数据块的第一读取命令；确定针对第一逻辑数据块的读取操作总数等于或超过第一阈值；响应于确定针对第一逻辑数据块的读取操作总数等于或超过第一阈值，安排从持久性存储设备删除第一逻辑数据块。
