To confirm your flash drive uses SSS6698-BB:

If you suspect a USB drive in your drawer uses this controller, here is how to confirm without opening the casing. Solid State Systems Sss6698-bb

  • Use USBDeview: Look for the "Controller" field. If it says SSS 6698-BB, that's it.
  • Performance test: Run a simple CrystalDiskMark. If sequential reads hover between 80-100 MB/s and writes are under 20 MB/s, it is likely this controller.

    • A low-power embedded processor executes the firmware. In the case of the SSS6698-BB, the firmware is often stored in the NAND flash itself, or in a small internal ROM, allowing the drive to be recognized by the PC. To confirm your flash drive uses SSS6698-BB: If

    Technicians frequently utilize specific MPTools for the SSS6698-BB to repair corrupted USB drives. If a drive becomes unrecognized by the OS or displays incorrect capacity (a common firmware corruption issue), the MPTool can reprogram the controller, repartition the memory, and restore factory settings.

    Unlike modern NVMe USB drives that throttle due to heat, the SSS6698-BB runs cool. Its low power consumption (under 0.5W active) means it never needs a metal heatsink case. This is a major advantage for drives that need to remain plugged in for hours.

    Due to a lack of a robust write cache flushing mechanism, removing a drive powered by the SSS6698-BB without using "Safely Remove Hardware" has a high probability of corrupting the file allocation table (FAT/MFT). This is especially true for exFAT-formatted drives.
