Solid State Systems SSS6698-BB: An In-Depth Technical Review of the USB 3.0 Flash Drive Controller

Typical performance trade-offs

• Low RDS(on) → lower conduction losses but generally higher gate charge and larger die size.
• Low VDS rating → faster switching and lower RDS(on) but limited to lower system voltages.
• Package thermal limits determine sustained continuous current more than absolute ID rating.

Where it fails:

• Modern OS installation (Windows 10/11): The write speeds on the "Applying Windows image" phase will take hours.
• Large file transfers (video editing): The thermal throttling makes it frustrating.
• Reliable backups: The high corruption risk when unplugging makes it unsuitable for critical data.

c) Drive disconnects randomly

• Cause: Poor power delivery or overheating.
• Fix: Use a powered USB hub; avoid USB 3.0 ports with long cables.

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.

The SSS66xx series represented their third generation of USB 3.0 controllers. The SSS6698-BB is a specific stepping of their 6698 family, designed to balance cost, power consumption, and sequential read performance. Solid State Systems Sss6698-bb

Performance & Real-World Behavior

Let’s be honest: this is not a performance controller. In real-world tests: Solid State Systems SSS6698-BB: An In-Depth Technical Review

• Read speeds max out around 20–25 MB/s
• Write speeds often drop to 5–10 MB/s, especially with small files or nearly full drives
• Random IO is poor — don’t expect to run an OS or applications from it

However, for its intended purpose — distributing files, moving documents, or booting a lightweight live Linux — it works adequately. Low RDS(on) → lower conduction losses but generally

6. Repair and Data Recovery

For technicians, the SSS6698-BB is a common sight in data recovery labs.

• "The Drive is Not Formatted" Error: When the firmware parameters become corrupted, the drive will often appear as "No Media" or prompt the user to format it.
• Solution: Using the specific MPTool for the SSS6698-BB version, a technician can perform a "low-level format." This re-flashes the firmware and re-initializes the NAND mapping.
• Caveat: This process destroys all data on the drive. It is strictly for reviving a dead drive for reuse, not for retrieving lost files.
