Pros: Amazing difference in speed of loading, and working with Windows 10.

Cons: None , so far.

Overall Review: I used different cloning-software (EaseUS ToDo backup, version 12), because my source original Hard disc-drive had 'bad-sectors', and I had created a rescue disk (DVD) already with their utility. The cloning process went well with that tool, and the use of the new Crucial SSD has been very smooth. I'm very satisfied with it!
