Manufacturers save money by using thin plastic shells with no thermal pads. The controller has no path to dump heat into the outer casing. Instead, the heat stays trapped inside, cooking the NAND chips and the controller itself. Part 3: The Symptoms of an Overheating PS2307 You don’t need a thermometer to diagnose this. If your Kingston or Corsair drive exhibits the following, you are suffering from the classic "PS2307 hot" syndrome:
A: Yes, many revisions of the DT100 G3 use the PS2251-07. It is notorious for overheating. phison ps225107ps2307 hot
A: Absolutely. Move the PCB into a metal USB enclosure with a thermal pad. This drops temps by 20-30°C. Manufacturers save money by using thin plastic shells
Early revisions of the PS2307 firmware had no temperature throttle. The controller would run at full speed until the NAND flash's solder joints began to reflow (soften). Later firmware added throttling, but it is reactive, not preventative. By the time the throttle kicks in, the drive is already dangerously hot. Part 3: The Symptoms of an Overheating PS2307
