Solid State Systems Sss6698-bb May 2026

Here’s a blog-style post about the Solid State Systems SSS6698-BB controller, written for a tech or data recovery audience.

However, the SSS6698-BB remains relevant in two contexts: Solid State Systems Sss6698-bb

• B – Second major revision of the silicon (bug fixes for prior versions)
• B – Standard commercial temperature range (0°C to 70°C)

2. Hardware Architecture and Specifications

The SSS6698-BB is engineered as a single-chip solution for USB mass storage devices. Its architecture is designed to optimize the performance of the USB 2.0 standard while managing the complexities of NAND flash memory. Here’s a blog-style post about the Solid State

• Removable Disk: Standard configuration.
• Local Disk: Configuring the USB as a fixed HDD.
• CD-ROM Partition: Creating a read-only partition (often used for manufacturer software or security software).
• Password Protection: Implementing hardware-level encryption and write-protection features.

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.

Controller Marking: 3S6698-BB (often identified in diagnostic tools as SSS6698 or TC58NC6623). B – Second major revision of the silicon

1. What is Solid State Systems (SSS)?

Before examining the chip, it is essential to understand the company. Solid State Systems (often abbreviated as SSS or USBest, a sub-brand) was a Taiwan-based IC design house specializing in low-cost USB flash drive controllers. At their peak in the early 2010s, they were a key player in the value and mid-range segments. Their controllers were famous for being "reference designs" for many OEM manufacturers (like Kingston, PNY, and Transcend), especially in drives intended for bulk data distribution rather than high-performance computing.
