disk-mark-me vs dperf

Both stand on disk benchmark software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

disk-mark-me

Free plan LinuxMac

Choose disk-mark-me if you want a free command-line disk benchmark with configurable tests and MB/s and IOPS results. Look elsewhere if you need stable macOS support or direct comparisons across operating systems.

dperf

Free plan LinuxSelf-hosted

dperf focuses on sequential read and write throughput across drives, with per-drive and aggregate reporting. It is not a fit when random I/O, IOPS or latency measurements are required.

disk-mark-me: what it does well

Measures sequential and random read and write performance.
Reports throughput in MB/s and IOPS.
Options cover target directory, file size, rounds and test type.
Released under the MIT License.
Supports Linux handheld systems running JELOS or ROCKNIX.

What to know first

macOS support is marked beta.
The script requires fio and several command-line utilities.
Results should not be compared directly across operating systems.
Intensive write benchmarks can contribute to SD card wear.

dperf: what it does well

Benchmarks multiple drives simultaneously.
Ranks drives by throughput.
Configurable block size, file size and concurrent operations.
Verbose mode reports per-drive statistics and aggregate totals.
Prebuilt binaries listed for four architectures.

What to know first

Does not support random I/O tests.
Does not measure IOPS or latency.
Requires Linux and direct I/O support.
Needs temporary space based on file size and I/O operations.
