Edit: Magician updated to 4.7 but alas no change. The method below still works however. (This is of course running on the RTM version of Windows 10 as we are long past the preview versions) Anyone who owns a Samsung Evo 840 SSD knows that Rapid mode can not be enabled using versions of Magician software 4.5 and 4.6. under Windows 10. However if you can find a copy of Magician software 4.4 then Rapid mode can be enabled in the Windows 10 environment. I did find a link to a copy of 4.4 here: Download Samsung Magician by Samsung Once you have the 4.4 version installed download the latest copy of Magician software here: Samsung SSD Support | Samsung SSD US Simply install the 4.6 version over the top of the 4.4 version. You'll get several prompts and reboots but ultimately it means Rapid mode will still be enabled at the end of it all. Do make sure you exit the Magician software before overwriting, simply right click the taskbar icon and click exit then run 4.7 Do not disable Rapid mode if your using version 4.6 as you won't be able to enable it again and you'll have to repeat the above process to get it back. I've tested the above procedure using my Evo 840 and it works fine. I do not think this will work for 850 users however.
