The Performance Benchmark also has its own page in the software. On this tab you can test other SSDs not manufactured by Samsung. This is an easy way to get a quick comparison of your installed storage products, even HDDs.
Samsung's Performance Optimization feature took around 10 minutes to finish on our empty 840 EVO 750GB drive.
The feature fills your Samsung SSD with large sequential temporary files and then deletes them. This starts a chain reaction with the operating system, TRIM kicks in and your spare area gets a nice cleaning. Your existing data is safe since the software only fills free space. This does mean you write a lot of data to the drive and thus you're wearing through the P/E cycles.
When the files delete, your original data remains, and so does the amount of space you had before starting the operation.
Easy Firmware Updates
The last tab in the Disk Management section of Magician 4.2 checks your current firmware against a database on Samsung's servers. If your firmware is out of date, you can update the firmware from within Magician with ease.
