The Samsung SSD Magician is a suite of tools to help you optimise, manage and generally learn more about your Samsung SSD.
A System Information tool provides useful information on your Samsung drive, for instance: its model name, serial number, firmware, drive capacity and more.
The Performance Benchmarking module calculates the speed of your drive when carrying out various operations: sequential reads, sequential writes, random reads and writes, and more. It compares each test with the previous one, too, so you can see how your drive speed is varying over time.
There's a Performance Optimisation tool, which makes use of the TRIM command to improve your Samsung drive's speed.
The Firmware Update tool allows you to create a bootable USB drive for updating the firmware on your Samsung SSD.
And a Data Clone option will presumably copy the contents of your Samsung drive, eventually, but it's not available in this version of the program.
