I've three of these in my pc build and they are really fast and solid SSD's. Thy work straight out of the box and they have a massive life span, probably the longest on the market...they'll see me out! Mine are housed in a Rocket m.2 heat sink and never go above 35c when in task. If you can grab one in the sales, even better, but 2TB at this speed and quality won't let you down. Having my operating system on one makes my pc super fast, with boot up that fast, you have to be ready to click 'delete' or you'll miss the BIOS option!
