Because it uses a standard SMI controller, it is often easier for advanced users to "re-flash" or fix using mass production (MP) tools if the drive becomes corrupted. Variable Flash Quality:
| Pros | Cons | | :--- | :--- | | Excellent random read for OS booting | No hardware encryption (unlike SM3281) | | Dual-channel reduces write amplification | Requires specific "Force Flash" files for rare NAND | | Runs 10°C cooler than IS903 | SLC cache performance drop is noticeable | | Supports up to 1TB NAND | No USB 3.2 Gen 2 (10Gbps) support | sm3280aa memory bar
The is a dual-channel, USB 3.1 Gen 1 (5Gbps) to NAND flash controller manufactured by Silicon Motion, a Taiwanese fabless semiconductor company. It is specifically designed for high-performance USB flash drives. Because it uses a standard SMI controller, it
Avoid any drive claiming "USB 3.2 Gen 2" (10Gbps) – the SM3280AA physically maxes out at 5Gbps. That's a red flag of a fake. Avoid any drive claiming "USB 3
