Added this to an Ideapad s145, and reinstalled a fresh (clean) copy of windows 10. Reinstalled the original hdd as a backup drive, copied over my old files to the new ssd and wiped the hdd clean. Very smooth process and the drive is very fast. Went from a 35-45 second boot time to 4-6 seconds. Crystaldiskmark shows read speeds of 2300, write of 1800. Not quite up to advertised specs but still plenty fast for what I need. And I suspect that may have to do with the computer and not the drive. Excellent value and highly recommended. Oh, and if you’re installing on an s145, you need an m2x6mm screw, not included. Ask your local Staples.
