The Samsung Magician software is designed to help users easily manage the health and performance of their Samsung SSD. From the main screen, users can check the health of their drives and view information like the serial number, firmware, capacity and the total bytes written. This screen also shows whether or not AHCI mode has been activated as well as the speed of the SATA interface.
Magician also gives users the ability to benchmark their drives and optimize the performance by forcing TRIM and Garbage Collection to run. In addition to this, users can download and apply firmware updates using the software.

Most operating systems are optimized for traditional hard drives. The OS Optimization menu provides options that help you configure your OS to work best with your SSD. Additionally, the Over Provisioning menu gives you the ability to optimize the performance and lifespan of your drive by resizing the partitions.

The Secure Erase feature provides the option to delete all data on an SSD in a way that it can never be recovered, restoring the drive to its original performance. Magician gives you the option to do this from within Windows. Otherwise, if your SSD is in a frozen state, you can create a bootable USB drive, CD or DVD.
Magician 4.2 introduces a new feature called RAPID (Real-time Accelerated Processing of I/O Data). When enabled, RAPID mode enhances the performance of the SSD 840 EVO by processing data on a system level through the use of free PC memory (DRAM) as a cache. Depending on your PC memory, you can expect higher performance and more efficient command processing, which improves with repeated tasking
In order to deliver the fastest and the most reliable user experience, RAPID mode focuses on improving the random performance with low queue depth and small size data. When frequently used (hot) data is recognized, it can also enhance the sequential performance. As Samsung points out though, improvement can vary depending on user scenarios, but at least in our case, we saw an increase of more than 57,000 points in the PCMark Vantage HDD test suite.
