ATTO Disk Benchmark is a widely-used disk performance measurement tool designed for Windows-based computers. Developed by ATTO Technology, this software provides a comprehensive suite of tests to evaluate the speed and performance of storage devices such as hard drives, SSDs (Solid State Drives), RAID arrays, and other storage mediums.

It's utilized by professionals and enthusiasts alike to assess the capabilities of storage solutions and to identify potential bottlenecks in data transfer rates.

As the industry's leading provider of high-performance storage & network connectivity products, it has created a widely-accepted Disk Benchmark freeware utility to help measure storage system performance.

As one of the top tools utilized in the industry, Disk Benchmark identifies performance in hard drives, solid-state drives, RAID arrays as well as the host connection to attached storage. Top drive manufacturers, like Hitachi, build and test every drive using the ATTO Disk Benchmark for PC.

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Use the tool to test any manufacturer's RAID controllers, storage controllers, host bus adapters (HBAs), hard drives, and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

Main Features
  • Customizable Tests: It allows users to customize test parameters such as transfer size, queue depth, and test length to tailor benchmarks according to specific requirements.
  • Graphical Results: The software generates graphical representations of disk performance metrics, including read and write speeds, IOPS (Input/Output Operations Per Second), and latency, providing users with intuitive visualization of results.
  • Multiple Drive Support: Users can benchmark multiple storage devices simultaneously, enabling comparative analysis of different drives or RAID configurations.
  • Export Options: Test results can be exported in various formats, including CSV (Comma-Separated Values) and HTML, facilitating easy sharing and analysis.
  • Cross-Platform Compatibility: While primarily designed for Windows, it also offers support for macOS and Linux through third-party software emulators.
User Interface

It features a straightforward and user-friendly interface, with clearly labeled buttons and options for initiating tests, adjusting parameters, and viewing results. The graphical representations of test results are presented in a visually appealing manner, making it easy for users to interpret performance data at a glance.

Installation and Setup

The installation process for the program is simple and straightforward, requiring users to download the setup file from the official website (if the program still exists officially, because it expired) or trusted sources like FileHorse and follow the on-screen instructions. Once installed, the software is ready to use with minimal configuration required.

How to Use

Using this tool is as simple as selecting the desired storage device or devices to be tested, configuring test parameters according to preference or testing requirements, and initiating the benchmark process.
