[NAME] Windows 10 is not on the Optane. The Optane acts as a cache for the HDD; the OS is on the HDD. I have not watched the videos, but basically, you need to disable the caching, replace the Optane with the new SSD, clone the HDD to the new SSD, disconnect the HDD when cloning is complete and then boot from the SSD. 
Hi all, I have an XPS 8930 with 16GB Optane memory which holds my OS, and a 1TB HDD. I was noticing that a lot of programs are taking a long time to start up, so I was thinking I'd like to get an SSD to store my programs. Unfortunately, I know absolutely nothing about computers. I understand that I could get a SATA SSD, although I have read that these are significantly slower than NVME M.2 SSDs. My M.2 slot is currently taken up by the Optane memory, which is why I am keen to replace it with a larger SSD. Would this be possible? What are the steps that I would need to take to achieve this? Like I said, I have never done anything like this before, and everything I have read so far is unintelligible to me. Please bear with me and treat me like I'm 5 years old. Thanks so much for your time.
