ATTO Disk Benchmark is one of the industry’s longest-standing, free storage performance measurement utilities used by top hardware manufacturers and review sites to test the raw throughput of storage systems. Developed by ATTO Technology, it stands out from other benchmarks by testing drive performance across a granular gradient of file transfer sizes. Key Features and Capabilities
Granular Transfer Sizes: The software measures performance by stepping through precise data block sizes, starting as small as 512 bytes up to 64 megabytes.
Visual Performance Profile: It outputs an easy-to-read bar chart that displays sequential read and write speeds side-by-side in megabytes per second (MB/s) or IOPS for each block size.
Broad Compatibility: It works natively across Windows and macOS. It is non-destructive, meaning you can safely benchmark formatted hard drives (HDDs), solid-state drives (SSDs), RAID arrays, and network-attached storage (SAN/NAS) without wiping data.
Advanced I/O Customization: Users can manipulate Queue Depths (how many read/write requests wait in line), adjust total test lengths (from 64KB to 2GB), and use Overlapped I/O modes. Understanding the Test Parameters
