A few weeks ago we reviewed the Crucial MX500 1TB SSD in 2.5-inch format and today we are testing the Crucial MX500 1TB SSD as M.2 version on OCinside.de. In the review we show the differences between the MX500 2.5-inch vs. M.2 SSD and test the M.2 both with and without passive M.2 heatsink on the @ASRock Z390 Extreme4 motherboard. So we can be curious whether the small surcharge to the M.2 SSD is worth it and how well the M.2 temperature can be lowered with a passive heatsink.
