Abstract
Methods for recording commands in memory and providing the recorded commands. In one embodiment, a data storage controller includes a memory interface configured to interface with a memory, a controller memory including a storage firmware and a record mapping table, and a processor. The processor, when executing the storage firmware, is configured to receive a record identifier, receive a command including data to be stored in the memory, and create an entry in the record mapping table associating the record identifier with a logical block address of the command. The command is received after the record identifier. The processor may receive a playback identifier that includes the record identifier and determine, using the record mapping table, a location of the associated command in the memory. The command is provided to an external device.
