| Metric | Result | Verdict | | :--- | :--- | :--- | | | 130–150 MB/s | Good for USB 3.0 | | Sequential Write | 20–45 MB/s | Poor. QLC bottleneck. | | 4K Random Read | 5–8 MB/s | Fine for OS bootables. | | 4K Random Write | 0.5–1.2 MB/s | Very slow. Not for databases. | | Temperature | 65°C–85°C under load | Runs hot . Needs airflow. | Time: 8GB drive = 2 minutes

Using the wrong MP tool (e.g., SM3267 tool on SM3265AC) will brick the controller into non-recoverable ROM mode. QLC bottleneck
