Data from a host is received into a volatile memory of a Data Storage Device (DSD) for storage on a disk of the DSD. Data received in the volatile memory from the host is identified for inclusion in a Power Safe Write Buffer (PSWB) and an indication is sent to the host indicating storage of data received from the host and identified for inclusion in the PSWB before storing the identified data on the disk. In the event of an unexpected power loss of the DSD, the identified data is transferred from the volatile memory to a Non-Volatile Solid-State Memory (NVSM) of the DSD.
