After our test of Crucial MX300 2 TB SSD we take a look at the 2280 M.2 SSD from the MX300 series. We test the Crucial MX300 525GB M.2 SSD and compare the benchmarks with SSDs from Intel, Samsung and other SSDs. Another subject is particularly interesting at M.2 SSDs and that is the temperature of M.2 SSDs. For this reason we have taken pictures with a thermal imaging camera and even published a M.2 thermal video in our OCinside YouTube Channel, where the M.2 temperature is shown during a benchmark in 4x speed!
