AS SSD Benchmark 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.
Free plan Windows
AS SSD Benchmark combines synthetic and copy-based SSD tests with score and measurement reporting. It is free, but its listed system requirement is Windows.

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.

AS SSD Benchmark: what it does well
- Tests sequential and random read and write performance
- Includes practical folder-copy and compression tests
- Reports scores and values in MB/s or IOPS
- Maker says version 2.0 handles NVMe SSDs
What to know first
- Windows is the only listed platform
- Author assumes no liability for damage from use
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.
