A firmware is a embedded software much like a BIOS. It provides electronical devices with crucial sets of software instructions. Without a firmware, electronical devices would lack the "knowledge" of how to function. In SSDs, firmwares are responsible for how the drive communicates with the system it's installed in, handled TRIM, Garbage Collection, and manages how data is being distributed among the drive's capacity. Firmware updates may contain improvements in terms of compatibility, performance or reliability as well as corrections of bugs that may have caused issues in certain situations. KIOXIA recommends keeping the firmware of SSDs up to date.
