Crucial MX300 1TB SSD Review

Crucial MX300 1TB SSD Temperatures

Temperatures have always played a critical role on storage drives and in recent years we’ve seen it cause drives to fail prematurely and we’ve even seen some SSD performance results change for the worse if components were too hot or too cold. Since temperature is an important thing to keep an eye on we check the idle and load temperatures on all of the drives that we review. To get the idle temperature results we leave the drive sitting on an open air test bench in a room that is 19C. For the load numbers we use IOMeter to write 128KB to the drive sequentially for 20 minutes and record the top temperature.

The Crucial MX300 1TB drive had an idle temperature of 25-26C and we found that it topped out at 51C after doing 350GB of straight 128KB sequential writes across the entire drive with IOMeter. That’s beyond the norm, so we stopped paying attention to the temps as 99.9% of people aren’t going to be pounding a mainstream consumer SSD that hard! It’s one thing to copy a movie folder that is 100GB in size versus filling a third of the drives capacity up all at once. Crucial has Adaptive Thermal Protection technology that dynamically adjusts internal settings to lower temperatures to reduce the risk of damage caused by overheating. From what we gather there is no way of knowing what this ‘technology’ is doing or when it is on, but we’ll just assume that it is working.
