Pros: - I purchased a 1TB 860EVO to replace my overtaxed 500GB 840EVO. As with its predecessor, the 860 performs wonderfully. - I used the Data Migration software that I was able to download from Samsung support and it cloned my new drive flawlessly.

Cons: - I have no issues with the SSD itself. However, the process for performing the data migration is not the most intuitive. I ended up calling Samsung support (1-800-Samsung) twice for clarification: 1) use the Data Migration software and NOT Samsung Magician to clone a new drive and 2) it is recommended that all programs be closed, that 3rd party anti-virus programs be disabled temporarily and that the Internet connection be disabled/disconnected during the migration. These were helpful details that were not obvious from other sources of documentation.

Overall Review: I recommend this product and will continue to use Samsung SSDs, should a future purchase be necessary again. I didn't feel that I needed the PRO version as my computing is not that high-end.
