ATTO Disk Benchmark
ATTO Disk Benchmark is a macOS utility for measuring storage performance across disks, SSDs, RAID arrays, and network shares.
What is ATTO Disk Benchmark?
ATTO Disk Benchmark is a disk benchmarking utility for macOS that helps users measure and compare storage performance. It is used to test read and write behavior on hard drives, solid-state drives, RAID arrays, and attached or shared storage so users can understand throughput under different workloads. The app supports variable transfer sizes, queue depths, custom test lengths, and continuous or snapshot-style benchmark runs, which makes it useful for hardware evaluation, troubleshooting, and performance tuning. Power users, IT professionals, reviewers, and anyone validating external drives or storage upgrades can use it to see how a device performs in realistic file-system-based tests. ATTO publishes the app as part of its storage software lineup for users who need a focused Mac utility for storage analysis.
Key features
- Measure read and write performance for disks, SSDs, RAID arrays, and network shares
- Run benchmarks with variable transfer sizes and queue depths
- Capture one-time benchmark snapshots or run tests continuously
- Use custom test lengths to compare different storage workloads
- Test file-system-level storage performance without destructive formatting
- Benchmark multiple disks during a test workflow

Safety overview
Status: Safe
This is a legitimate storage testing utility for macOS. It needs access to a location you choose for benchmark test files, and its disk activity during a test is expected for this type of tool. Because benchmarking writes and reads large amounts of data, avoid running tests on folders that contain work you are actively editing, and expect heavy disk usage while a benchmark is in progress.
Recommendation: Keep ATTO Disk Benchmark if you use it to test drives, external storage, RAID setups, or network shares. If you no longer benchmark storage on your Mac, you can remove it without affecting macOS, though any saved preferences or benchmark-related files may be lost.
