CrystalDiskMark is a utility that allows the user to benchmark their disk and drive performance. It allows the user to determine how the drives perform best and to determine the typical operating performance.
It is a easy to use tool that can perform up to 9 test runs on the hard drive. The user can select exactly how many test runs he/she wants the app to perform on the hard drives. The test is done separately for each drive and the user has the option of selecting the size of the test being performed( 1000 MB or 1GB being maximum).
The application is designed to test the read and write performance of the hard drive. In order to do this, three separate sub-tests are performed; Small file read, Large file read and File write. The final results are computed as an average of the three sub-tests performed and the results are measured in MB/s.
The tool is available free of cost and no installation is required. All you have to do is extract the files on to your hard drive and you’re ready to go. Also there are no compatibility issues. It Measure random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed. It also comes with theme support. It works well with Windows XP, Windows Vista and Windows 7 computer.
