SSD Benchmark review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

SSD Benchmark is a lightweight, open-source command-line utility for measuring sequential disk write performance on macOS and Linux. It suits developers, system administrators, and performance analysts who need a focused way to run repeatable write cycles from a terminal. The tool writes random data in sequential 8 MB blocks, measures total writing time and throughput, and can target the disk associated with the current working directory or a directory specified by the user.

Its strongest capability is repeatable sequential write measurement. Tests run across multiple cycles and report minimum, maximum, mean, and standard-deviation results, giving buyers more than a single throughput figure. IOPS reporting adds another view of performance, while configurable block sizes allow the benchmark to fit different test requirements. Command-line execution and a configurable target directory also support scripted or directory-specific workflows. According to the published product details, the tool is free and open source rather than divided into paid plans.

SSD Benchmark is a good choice when the evaluation centers on sequential write throughput, timing, and IOPS on macOS or Linux. Its scope is narrower for buyers comparing mixed storage workloads: the documented feature set does not include random I/O testing or latency measurement. Choose it for a compact, write-focused benchmark with configurable cycles and blocks; choose another tool when random access behavior or latency analysis is central to the decision.

SSD Benchmark pros and cons

• Where it wins
  • Measures throughput, write time, and IOPS across test cycles
  • Reports minimum, maximum, mean, and standard-deviation results
  • Supports configurable target directories, block sizes, and CLI execution
• Where it doesn't
  • Focuses on sequential writes rather than random I/O tests
  • Does not provide documented latency measurement
  • Supports macOS and Linux, with no other platforms listed
