So after nine years I got a new gaming PC over the holiday sales. Came with a 240gb SSD Boot Drive and a regular 1TB HDD. I like the speed of the SSD (by the time I fully settle into my chair windows is already loaded, haha), but 240gb is pretty small so I want to upgrade. The motherboard has a slot for a M.2/NVMe drive. Are these worth it over a regular SSD? Is the increase in speed substantial enough to justify the increased price over regular SSD? I've read they have heating issues, so I'd have to buy a heat sink. I'll probably want to use it as the boot drive, so should I even bother with cloning or do a fresh windows install? Or, should I just go the easiest route and toss another larger regular SSD in there for games/files, keep the 240gb as the boot drive, and skip the NVMe altogether?
