I used it to replace my old m2 sk hynix sc311 sata 256gb (Dell G5 15 5587 laptop). I didn't notice significant speed differences, although the Evo is faster, but what impressed me is the Samsung Data Migration cloning software. Additionally, I combined it with a RaidSonic Icy Box IB-183M2. I put the EVO in the Icy box and connected it to the laptop. After that, the software took care of the rest. Finally, I removed the hynix from the laptop and installed the EVO, and that was it. No formatting or anything. It was as if nothing had changed. Even the open browser tabs were in their place. Programs, settings, everything was there!!! 3 tips. A) When you first install the EVO and the system doesn't recognize it, you just need to go to disk management, right-click on the disk description, and select new extended volume (all disk colors will be blue except for the EVO, which will be black). After extending, it will turn blue and be recognized normally. B) It's good to check for errors on the old M2 from the command line. (From search -> command line or CMD -> right-click and run as administrator, then type chkdsk /f) and C) Before cloning, close everything running in the background, tabs, games, antivirus programs, even the internet. Then simply click on clone and step away. When the process is finished, the computer will shut down on its own (so it's convenient to leave it overnight as it copies files).
