What ATTO Disk Benchmark is
ATTO Disk Benchmark is a free utility for measuring storage read performance, write performance, and I/O throughput. It can assess hard drives, solid state drives, and storage systems, including network or block storage accessed through a file system. Users can capture snapshots or run continuous benchmarks, adjust transfer sizes and queue depths, and test multiple disks in each test. The feature list describes file-system performance tests as non-destructive. The benchmark also supports custom test profiles, command-line use, and automation; results can be exported as BMK, TST, or LOG files, or sent to print. ATTO identifies drive manufacturers, IT professionals maintaining IT ecosystems, and hardware review sites as users of its Windows benchmark. Windows release v5.00.3 and macOS release v1.01 are listed. ATTO offers technical support by email and contact form. The company was founded in 1988 and is headquartered in Amherst, New York.
