Release history

New 🎉

• Time-based testing: set a duration (default 30 seconds) for the write test and the read test, sampled once per second.
• Test file size setting.
• IOPS and latency, plus per-second minimum, maximum and last throughput.
• Export results to a text report or CSV, including drive details (model, bus, SSD/HDD, capacity) and the configuration.

Changed 😎

• Redesigned interface: larger headline figures, a clearer graph, a status line, and DPI awareness.
• "Chunk Size" is now "Block size". "IOs" and "Iterations" are replaced by Duration and Test file size.
• Results now reflect the drive rather than the system cache: reads bypass the cache, cached writes are flushed inside the timing, and test data is incompressible.
• The average is now total data divided by total time.
• Runs without administrator rights. Settings are saved per user.
• The installers now require Windows 10 or later.

Fixed 🐛

• Settings were never actually saved.
• Invalid input could go unreported.
• The free-space check could overflow.
• The test failed to start on drive roots that need administrator rights.
