ATTO Disk Benchmark is a small but very popular tool for testing the performance of data storage devices, such as hard drives, SSDs, flash drives, memory cards, etc. It can also be successfully used to test the configuration of RAID controllers. ATTO Disk Benchmark's tests are based on the measurement of read and write operations using different data sizes.

This allows the user to test the speed of the disk, the results of which will reflect the actual behavior of the device, as if it was used in everyday work with a computer, e.g. during the transfer of large files, etc. The results will reflect the actual behavior of the device, as if it was used in everyday work with a computer, e.g.

during the transfer of large files, etc. The tool allows you to determine, among others, the size of the transferred data packet (from 0.5 to 8192 KB), their total size (from 64KB to 2GB), the number of read/write operations performed simultaneously, while providing the possibility of continuous testing. ATTO Disk Benchmark also has an I/O comparison function.

All test results are presented in the form of bar charts, which can be saved or printed out. A great advantage of the program is that it does not need to be installed on a computer. The tool is ready to work right after downloading.
