So i checked my HDD with HDD sentintel and my ssd was 30 degrees celcius with 95% health and it said that it had 900 days left so it means that in 900 days it will die?
also the temps of my hdds was caviar blue 500gb-41 degrees toshiba 1tb 39 degrees
AMBIENT TEMP 35 degrees
30 to 41C HDD temps with 35C ambient temperature are to be expected, they can get even hotter at lower ambient temps, so don't worry about those readings... 95% health is good and you didn't mention performance but it should be at 100% (right?)... you also didn't mention bad sectors so the scan probably didn't find any.
And 900 days (2.5 years) is an estimation not a prediction, and it can remain the same for a long time so don't take it in a negative way but quite the opposite.
