Why does an SSD slow down after prolonged use?

In fact, many brands of SSDs are not equipped with original heatsinks. At the same time, there is no space for installing heatsinks on hard disk boxes or laptops that use SSDs. Therefore, in the face of overheating, the solutions given by SSDs are actually the same as those of CPUs and laptops. The graphics card is the same, that is, the overheating protection mechanism. There are temperature sensors in the main control, flash memory, and DRAM cache on the SSD. Some of the sensors may be built into the PCB. These temperature data will be transmitted to the main control, and some data can be fed back to the system through SMART. As for whether the temperature is too high? The judgment is made by the SSD master controller. The SSD manufacturer can set the critical temperature in the firmware. If it exceeds this line, the frequency of the master controller and the flash memory will be reduced, so as to reduce its own heat generation, thereby reducing the temperature
