Memory Bar ((install)) - Sm3280aa

| 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 |

When an SSD's controller dies, technicians desolder the NAND chips and mount them onto an SM3280AA board. The SM3280AA acts as a "NAND reader" allowing raw sector access via dd or WinHex. sm3280aa memory bar

: A dual-channel flash drive controller that supports high-speed data transfer and compatibility with modern NAND types. | Pros | Cons | | :--- |

If your dies, hope is not lost. Unlike monolithic "Chip-On-Board" (COB) drives where the controller and NAND are glued together, the SM3280AA has separate components. If your dies, hope is not lost

: Abruptly unplugging the drive while it is writing data can scramble the controller's instruction set. NAND Flash Wear

USB 3.2 Gen 1 SuperSpeed (5 Gbps), backward compatible with USB 2.0.
