@Fernando,
I am very surprise this Intel SSD Tool v3.4.0 is buggy !!
Looking at the screenshot: Intel SSD Tool detects a RAID member (Samsung 850 PRO 1 TB) as an Intel 750 1TB device (which does not exist) !!!

@Fernando,
Samsung Magician v5.0.0790 is now available.

Unfortunatly I did not suceed to install it..

Can not download ( yet ?) , when searching for updates Samsung ; latest version already installed ! ( 4.9.7 )

Available here (touslesdrivers.com):
Magician v5.0.0.790

Why not possible to install ?
According Samsung and your hardware it should be possible ............

@Pete12,
Yes, normally it should work. But, I get the error reported in my post.
Do you succeed on your side ?

Yes, it installed over the 4.9.7-version , its very small program now . I decided to uninstall competely , coz its not really an improvement !
If you have lots of RAM ( 32GB) and on Win10 ,you just dont need it , did not encounter less speed etc. after uninstall .
Positive is less services starting up and less tasks starting up , I wil test next days , but I think Im sure ; you dont need it , coz its not a real improvement for your system !!
Besides, Windows knows perfect how to handle SSD...........

@Pete12
Yes, I agree with you, I don't wait wait for miracle from Magician, it is only to check some informations and not to have this tool installed permanently.

You succeed to install over v4.9.7, but did you succeed to install from scratch as I had tried ?
If we need the previous version to be present to install v5.0 this is not a good point !

You can install from scratch also , I will not use it anymore , im gaining more speed by losing services and tasks ( from Samsung Magician ) , while this "Rapid Mode" does not give you any profit at all ! Maybe later , after real progressive update, will try again .

@Pete12,
I also have now uninstalled definitively this version because i get "some errors" message when I try to start Magician v5.0.
On my Sabertoothx99 v4.9.7 works fine, (but I don't need it).
V5.0 from scratch does not install properly.
V5.0 installed over v4.9.7 does install but does not launch.
My hope was to get a better version with V5.0.. I wait for a next release !
