I've installed the Crucial MX-300-525GB version on my Dell 7559. The benchmarks show good results but Windows 10 on it just seems sluggish. My programs take time to open... I have a Lenovo T430 i5-3320 which opens up Premiere Pro much faster than it does on this SSD on the i7-6700 Dell 7559. Maybe it's a driver issue. So in short it works but I'm having performance issues with the 525GB version which is not officially supported by Crucial on this Dell 7559. The 275GB version might provide better performance.
Have attached benchmark results, if they're of any interest to you.
