ATTO Disk Benchmark
Amherst, New York, USA
What it is
ATTO Disk Benchmark measures storage system performance, including 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 run. The feature list describes file-system performance testing as non-destructive. ATTO says the benchmark can test OEM RAID controllers, storage controllers, host adapters, hard drives, and SSDs. It also supports custom test profiles and command-line use or automation. Results can be exported in BMK, TST, and LOG formats, or sent to print. Windows and macOS versions are listed, with different release versions: v5.00.3 for Windows and v1.01 for macOS. ATTO identifies drive manufacturers, IT professionals maintaining IT ecosystems, and hardware review sites as users of its Windows benchmark. The pricing model is free. ATTO provides technical support by email and contact form.
