In this chapter, we will discuss the common solid-state drive (SSD) firmware features. We will start by discussing the mapping table, which is used to store the mapping between logical block addresses (LBAs) and physical block addresses (PBAs). We will then discuss bad block management, which is used to identify and manage bad blocks on the drive. We will also discuss wear leveling, which is used to distribute writes evenly across the drive to extend its lifespan. Garbage collection is another important feature that is used to reclaim unused space on the drive. We will also discuss data retention, error handling, power-loss protection, and unexpected shutdown support.
