Our verdict on ATTO Disk Benchmark

ATTO Disk Benchmark is a free desktop utility for measuring storage read and write throughput. It is aimed at drive manufacturers, IT professionals, and storage-system testing workflows that need configurable tests across HDDs, SSDs, RAID arrays, storage controllers, host adapters, attached storage, and storage reached through a file system. Editions are provided for Windows and macOS, with support for testing multiple disks in each test.

The pricing structure is straightforward: the Free plan is listed at $0.00 USD as a one-time price for both Windows and macOS editions. That plan includes configurable transfer sizes and queue depths, adjustable test lengths, overlapped I/O, direct I/O, continuous benchmarks, and comparison testing. Completed results can be saved or printed, while saved test files and error logs support repeatable workflows. On Windows, command-line execution is available for saved test files, adding an automation option for scripted benchmark runs.

Its main strength is depth within storage throughput testing rather than breadth across every area of PC performance. The workload coverage includes disks, arrays, controllers, adapters, and attached storage, making it suitable when transfer behavior and read/write results are the priority. The tradeoff is scope: buyers seeking a broader PC benchmark covering processors, graphics, memory, or application performance should choose a more general benchmark suite. ATTO Disk Benchmark fits users who want a configurable storage-focused tool at no software cost, especially on Windows or macOS; Windows users also get the documented command-line path for saved test files.
