For continuing with the second test stage, we have had to fill the drive of 50%, while writing continuously to it. The process was monitored carefully, to check out the pseudo-SLC cache behavior as well. The P3 does have reports from two separate sensors, so we can note both NAND and controller temperatures at the same time!

The write speed started at optimal levels:

The controller temp reached about 64 degrees Celsius, while the NAND remained cool at about 48 degrees Celsius:

250GB of written data, and we still got good write speeds:

The controller has reached about 69 degrees, while the NAND raised the temperature to about 53:

After 782GB of written data, the drive did still perform admirably:

We noted a 74 degrees Celsius temperature for the controller and 58 degrees for the NAND:

The speed has dropped sharply after writing 1048GB and even if the Windows 11 speed indicator dialog was showing a locked progress, Task Manager was more accurate and displayed the real picture:

Till the drive became half-full, the transfer speed remained between 85 and 95MB/s, since the pSLC caching was fully filled; we noted that even under maximum stress, the controller temperature did not pass over 76 degrees Celsius, while the NAND remained at a safe 63 degrees temperature:
