I want an M.2 SSD (rather than a 2.5 or 3.5 since my case CMH500 only has 4 storage spaces and I don't wanna fill them right away) with good reading speeds that would boot my PC up in, say, 10-15 seconds or so. I don't want a 140 GB one or so. I'd rather go with a 240GB one since I'll be using it for a while until I get my first HDD or 7200RPM. So far, I've settled for the Corsair MP510 240GB. Anything you can suggest with similar performance but less pricey? Thanks!
