Thanks for your response. I also have a Samsung 860 EVO 1TB sitting here with me which shows a similar story to the MX300 with the temperatures. Idles significantly lower and light loads don't increase much over idle. Just seems more consistent. I repeated the test on the MX500, 300 and 860 but the MX500 doesn't seem to hit that wall other drives do. The EVO for example topped out at 42C in a 32GB write about half way through then hovered there whereas the MX500 kept climbing until the write was over. Increasing the write makes it hotter whilst having no effect on the EVO. I’ve also seen a review which stated that the MX500 1TB, outside of it’s case, reached a maximum of 50C on the controller in there heavy write test and they mentioned it would be likely for it to be cooler when in the enclosure, which initially sparked my interest in the temperatures. Maybe I'm just overthinking it. I'm just concerned that routinely allowing it to reach high temperatures will be detrimental to it's lifespan and the erratic behaviour of the temperature isn't something I've usually seen on a SSD. Although ironically I’m probably doing more harm writing to it worrying about the temperatures than the actual temperatures themselves :) Thanks again for your reply.
