Abstract:
Example storage systems, storage devices, and methods provide a write group journal for identifying incomplete writes. Related write request indicators are stored in a non-volatile journal in a solid state drive to identify a related write group and indicate whether the related write group has been stored in storage locations corresponding to physical page addresses. An event notification is sent to a host system when the related write request indicator indicates that the group was incomplete at the time of a data loss event.
