I have a E7450 with Nvidia graphic card and 128gb SSD with Windows 10. I would like to upgrade the SSD to around 500gb and would like to know what others have tried or would recommend. I tried a crucial MX300 2.5inch 525gb SSD which did not work. Thank you.

Note: mSATA (which this system uses) is not the now more common M.2 format. It's completely different.
