Abstract

Systems and methods are provided that may be implemented to collect and log (or record) data or information regarding logical block address (LBA) access activity occurring in a solid-state drive (SSD) non-volatile memory storage device of an information handling system. The LBA access activity may be collected, logged and store at the SSD storage controller-level, and may be retrieved and processed and/or analyzed to develop and then implement non-volatile memory management techniques to optimize and improve SSD device operation and performance (e.g., by decreasing read/write completion times), optimizing SSD media endurance (e.g., by extending the useful life of the SSD media), etc.
