Download CrystalDiskMark
CrystalDiskMark is free benchmark utility designed to test performance of hard drives. The software is available for Windows. It is easy to use and it doesn't require installation.
Testing hard drive performance using this utility is really easy. You need to indicate number of routines of each test (1 to 9), select data sample size (from 50 to 4000 MB) and partition. CrystalDiskMark displays results in a readable table consisting of an average read and write data, and simple diagrams. The application creates files on disk and measures the speed of their records to check the HDD performance.
CrystalDiskMark also checks the data reading speed by displaying information about the transfer in the form of MB / s. You can test all parameters offered by the program (large and small files) as well as only selected data sample. CrystalDiskMark is used by many benchmark portals for comparing performance between different storage media.
