Further, the method also involves writing a first table of contents corresponding to the stored critical metadata to the non-volatile memory and storing a pointer to the first table of contents. A Solid State Drive (SSD) including a memory controller, a non-volatile memory, and a power loss protection capacitor. The memory controller is configured to identify critical metadata corresponding to data previously written to the SSD.
