tracks which physical block contains only valid pages.

Explanation:

Flash translation layer or FTL is a system made up of software and hardware that manages solid-state drive or SSD operations. It implements data concurrency techniques like striping, interleaving, and pipelining to generate a high throughput. It also performs logical to physical addressing amongst other functionalities.

The FTL also tracks which physical block in the memory that contains only valid pages by performing a bad block management process, isolating and discarding the blocks with no valid pages
