D-Bench

Summary

D-Bench is a free Windows utility for measuring read and write performance on SSDs, HDDs, NVMe drives, and USB storage. It reports throughput in MB/s, IOPS, and average latency, with read and write throughput separated. Workloads can be sequential or random, and settings include block size, queue depth, and thread count. HDD, SSD, and Flash Drive presets are available, alongside controls for access pattern, read/write mode, read percentage, duration, warm-up, and cool-down. The drive selector lists ready drives with their letters, volume labels, free space, and total capacity. Users can manage test sets by adding, updating, removing, reordering, duplicating, or clearing tests. Results can be exported as plain TXT files or styled, self-contained HTML reports. D-Bench uses unbuffered I/O and disables operating-system read caching for write tests as much as possible. Separate builds cover Windows Vista and 7, or Windows 8, 8.1, 10, and 11. Downloads come in Default, Blue, and Red themes; the listed free plan is 0.00 USD per free, with an approximately 470 KB download.

Who it is for

D-Bench suits Windows users who want to measure storage-drive performance with configurable sequential or random workloads. Its presets and report exports may help users who want to compare results across test settings.
