SAMSUNG MAGICIAN
Although the 850 Pro comes with a software CD in the box still we recommend checking out the official Samsung support page to get the latest data migration and magician software suites.
We last saw the Samsung Magician when we reviewed the 840 EVO earlier this year and it hasn't changed much if at all so once again the intro screen has an overview of the drive.
The very first thing i recommend checking is the firmware tab since from here you will see if you need to upgrade to another version or not.
Although you can perform a fast benchmark to check the speed of your drive and you can also "optimize" the OS for use with an SSD the most important feature of the Samsung Magician is the RAPID Mode.
RAPID (Real Time Acceleration Processing of I/O Data) mode basically uses a X amount of RAM from your system (DRAM is much faster compared to NAND flash) to cache frequently accessed data (in short it works like a RAM disk).
Once RAPID is enabled you will need to restart your system (you can also use the verify button at the overview screen to verify the drive).
