ADATA & XPG SSD Data Recovery

Dual Cortex-R5 core NVMe Gen3 controller with 8 channels and onboard DRAM. The SM2262EN was the original spec; ADATA later substituted the SM2262G in some production runs without changing the model number. Both controllers support hardware AES-256 encryption. PC-3000 SSD's Silicon Motion Active Utility covers the entire SM2262 family. Recovery involves shorting the ROM pin to access the controller in safe mode, dumping the firmware tables, and reconstructing the flash translation layer. The DRAM provides better power-loss protection than DRAMless designs, so firmware corruption on these drives is typically limited to the FTL mapping rather than wholesale NAND damage.

4-channel SATA controllers. The SU800 uses the SM2258 with onboard DRAM. The SU650 (some variants) uses the SM2258XT, a DRAMless variant that stores FTL metadata directly in NAND. The DRAMless design makes the SU650 more vulnerable to power-loss corruption. The most common failure mode on the SM2258XT is the "Keep BSY" state: the drive briefly identifies then goes permanently busy. PC-3000 enters ROM mode via controller pin shorting and rebuilds the corrupted flash translation layer. The SM2258XT uses XOR data scrambling rather than full AES encryption, which makes chip-off technically feasible as a last resort if the controller cannot be revived.

DRAMless NVMe Gen4 controller. The Legend 800 pairs this controller with QLC NAND, combining two cost-reduction technologies that both increase failure risk. Without onboard DRAM, the FTL mapping lives in NAND. QLC's tighter voltage margins (16 states per cell) mean the NAND degrades faster and produces higher bit error rates as the drive ages. PC-3000 SSD's Realtek module accesses the controller to rebuild corrupted FTL tables. QLC recovery requires additional read-retry iterations to coax correct data from cells that have shifted beyond their original voltage thresholds.

NVMe Gen4 drive with onboard DRAM and TLC NAND. The DRAM stores the FTL mapping table, reducing power-loss vulnerability compared to DRAMless designs like the Legend 800. Failures are less common but when they occur, they typically involve firmware corruption from interrupted writes or PMIC failure on the PCB. Hardware AES-256 encryption makes chip-off not viable; board-level repair to preserve the original controller is required. We identify the specific controller on the PCB before selecting the recovery workflow.

High-performance 8-channel NVMe Gen4 controller with onboard DRAM. The Gammix S70 Blade pairs this with TLC NAND for sequential read speeds above 7 GB/s. Early firmware revisions had stability issues under sustained mixed workloads, with some drives triggering KERNEL_DATA_INPAGE_ERROR or blue screens during heavy I/O. Later firmware updates resolved the stability problem, but drives that failed before the update need recovery. The IG5236 uses hardware AES-256 encryption, making chip-off not viable. PC-3000 SSD Extended covers InnoGrit controllers for firmware-level diagnostics and FTL reconstruction.

Cost-reduced NVMe Gen4 controller from Silicon Motion. DRAMless HMB design with 4 channels. The Legend 850 ships with TLC NAND, giving it better endurance than the QLC-based Legend 800, but the lack of onboard DRAM means the FTL mapping is stored in NAND and vulnerable to power-loss corruption. The SM2269XT shares the same PC-3000 SSD Silicon Motion module family as the SM2262EN and SM2258XT. Recovery follows the standard Silicon Motion workflow: pin shorting for ROM mode, firmware table dump, FTL reconstruction.
