CCSIO Benchmark is a program for testing the performance of hard drives and other storage media. The speed of reading and writing data is checked, and the highest results are recorded on an attractive chart and in the form of raw data in a table. After booting, you will first need to indicate the partition you want to test. In the drop-down window you can see all the letters assigned to disks (also removable ones), but there are no labels, so it is necessary to use only letters. Below are also presented the basic parameters, including the model name of the selected hard disk drive. The test is started with the button in the lower part. The window will be extended to display charts as well. These are drawn on an ongoing basis, along with successively tested data packages. The highest score so far is marked with a different colour. The tabular version of the data can be displayed on the Raw data tab.
