On first sight seems that everything is OK with your disks, but you cannot use the Western Digital Diagnostics Tool for Samsung drive(s). And one more thing, it would be advisable to use the two chairs one at a time, ie not at the same time simultaneously. They can interfere with each other. Unfortunately, you do not show the actual working hours and health of the discs in any of the pictures.
Absolutely true, You can't. These widgets only shows common data and nothing else. Your drivers seems to be OK, only one thing, what is a bit strange, it is temperature. It is mostly OK and there is nothing dangerous, but is be better if the temperatures are less than 42 degrees C, but even if they are 53-54 dgrees is nothing wrong. Sometimes there is nothing to do to get the temperatures less than 42 dgrees C, but sometimes is needed cleaning dust inside the computer, specially if it is laptop. On some older computers the temperature is always between 44-54 degrees and there doesn't help nothing. It isn't dangerous for SSD's. It is dangerous when the temperature is regularly 60-70 degrees and above. One thing you might want to look, it is the temperature after the computer has been completely shut down for at least half an hour and then restarted. Then it should be about the same as your room temperature. If the sensor shows a higher temperature then the sensors have probably wrong graduation but you cannot change them any way. Just know that the actual temperature is so much different than the displayed temperature is different from the room temperature. PS. Many sensors indicate the wrong temperature.
