This is the most fascinating part of the SM3265AC. This controller is infamous for its "Mass Production Tool" (MPTool) compatibility. Here is a detailed report on the topic:

For the uninitiated, the SM3265AC is a USB 3.2 Gen 1 Flash Controller manufactured by Silicon Motion. It is a generic, single-channel controller designed to be cheap, adaptable, and robust. You will almost never see this chip branded on a shelf under its own name. Instead, it lives inside the unbranded USB thumb drives, the promotional swag you get at conferences, and those too-good-to-be-true "2TB SSDs" selling for $15 on shady auction sites.

Is it fast? Not really. It won’t break any records against a Samsung T7 or a high-end NVMe enclosure. Is it consistent? Actually, yes. The strength of the SM3265AC isn't top-tier speed; it’s stability. It manages thermal throttling surprisingly well for a budget chip. I’ve seen these things get piping hot during sustained writes without crashing, which is more than I can say for some "premium" drives that overheat and disconnect the moment you try to move a 4GB file.
