Abstract
Various implementations described herein relate to systems and methods for a Solid State Drive (SSD) to manage data in response to a power loss event, including writing data received from a host to a volatile storage of the SSD, detecting the power loss event before the data is written to a non-volatile storage of the SSD, storing the write commands to a non-volatile storage of the SSD, marking at least one storage location of the SSD associated with the write commands as uncorrectable, for example, after the power is restored.
