Here is how this humble controller bridges the gap between practical lifestyle management and on-the-go entertainment.
The USB connector. Repeated thermal expansion and contraction (hot → cold → hot) can crack the solder joints holding the USB plug to the PCB. This is the #1 physical failure of PS2307 drives.
The Phison PS2307 represents a newer generation of SSD controllers, designed to address the growing demands of high-performance storage solutions. This controller boasts an advanced architecture, supporting up to 10 channels of NAND flash and incorporating cutting-edge technologies like PCIe 4.0 and NVMe 1.4. Consequently, the PS2307 enables SSDs to achieve unprecedented levels of performance, with sequential read and write speeds reaching up to 7000 MB/s and 5000 MB/s, respectively. phison ps225107ps2307 hot
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.

When a controller encounters a critical error—such as uncorrectable bit rot on the NAND flash where its primary firmware is stored—it goes into a . The processor continuously cycles at maximum frequency trying to re-read corrupted structural blocks or system code. Because it never enters an idle sleep state, it rapidly builds up heat, transforming a firmware error into a physical thermal issue. Phison PS225107 USB Drive. - HDD GURU FORUMS

If the drive is glitching due to pure thermal throttling, unplug it immediately. Let it rest for 10 to 15 minutes until it returns to room temperature.
Internal short circuits within the controller chip's power rails cannot be fixed with software. If the drive contains critically important documents, immediately stop plugging it into power to prevent further damage. You will need to hand the drive over to a dedicated data recovery lab that can physically unsoldering the NAND memory chip and read its raw contents using hardware like a PC-3000 Flash programmer .
