Here is a screenshot of Snipping the CrystalDiskInfo 4.3.0 SSD and HDD information software, where is immediately noticeable, that the Crucial SSD is now also equipped with a temperature sensor, which is able to throttle the SSD speed if the SSD reaches too high temperatures. BTW., in our test we have achieved up to approx. 67°C temperature, which is already very high.

SSD firmware update …

At review date, Crucial offered no newer firmware download than the already installed MU01 firmware for the M.2 M550 SSD.
