Locate the smaller, square chip (the controller) next to the larger rectangular chip (the NAND flash memory).

The SSS6698-BB fixed several errata found in the original SSS6698 (no suffix) and the SSS6698-AA, including improved stability with TLC NAND and better handling of USB 3.0 link negotiation. Solid State Systems Sss6698-bb

When you connect a drive using this controller, tools like (Windows) or lsusb (Linux) will report a firmware version like 6698_BB_1.2.79 . The number after the underscores indicates the NAND profile. Flashing the wrong firmware will brick the drive permanently. Locate the smaller, square chip (the controller) next

The is a USB 3.0 NAND flash memory controller developed by Solid State Systems Co., Ltd. (commonly abbreviated as SSS or 3S), a Taiwanese company known for producing cost-effective and widely used USB flash drive controllers. This chip is part of the 669x family, succeeding earlier models like the SSS6697 and SSS6695, and is designed to support modern TLC (Triple-Level Cell) and 3D NAND flash memories with higher capacities and improved performance over USB 3.0 interfaces.
