Regarding the FTL acronym:

"To hide the complexity of SSD internals, the controller usually contains a piece of software called an FTL (Flash Translation Layer); the FTL provides the host with a simple block interface and manages all the operations on the flash chips."

...

"A hybrid FTL uses page-level mappings for new data and converts them to block-level mappings when it runs out of mapping cache."
