Warning: Using the wrong firmware (e.g., QLC firmware on TLC NAND) causes immediate "Bad Block" errors.
| 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 SM3280AA is soldered onto a printed circuit board (PCB) alongside the NAND Flash chip(s). The compact nature of the SM3280AA allows for slim "Bar" designs (often resembling a slim rectangular stick). sm3280aa memory bar
The controller supports advanced firmware options including write protection, password protection, and secure partitioning. Performance and Utility As a "memory bar" component, the sm3280aa memory bar
