What ATTO Disk Benchmark is

ATTO Disk Benchmark is a free utility for measuring storage read and write performance and I/O throughput. It can test hard drives, solid state drives, storage systems, OEM RAID controllers, storage controllers, and host adapters. Users can adjust transfer sizes and queue depths, capture snapshots, or run continuous benchmarks. It can measure network or block storage accessed through a file system, and its feature list describes file-system performance testing as non-destructive. Multiple disks can be included in each test. The Windows download page lists version v5.00.3, while the macOS page lists version v1.01. ATTO identifies drive manufacturers, IT professionals maintaining IT ecosystems, and hardware review sites as users of its Windows benchmark. Results can be exported in BMK, TST, or LOG formats, or sent to print. Custom test profiles and command-line use or automation are supported. ATTO offers technical support through email and a contact form. The company is headquartered in Amherst, New York, and was founded in 1988.
