You’ve done the research, watched the reviews, and finally pulled the trigger on a blazing-fast M.2 NVMe SSD. You’re dreaming of instantaneous game loads and file transfers that finish before you can blink. I’ve been there and enjoyed the instant boot-ups from a new SSD too, but try moving a massive game library, and watch in horror as the transfer speed plummets from a god-tier 7,000 MB/s to a glaring reminder of your old spinning disk. When the progress bar slows to a crawl, it can be because your SSD has run out of SLC cache and is now writing to NAND, or because the drive is simply too hot.
