In their own words
D-Bench
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, with configurable block size, queue depth, and thread count. HDD, SSD, and Flash Drive presets offer starting points; additional controls include access pattern, read/write mode, read percentage, duration, warm-up, and cool-down. The drive selector shows ready drives with letter, volume label, free space, and total capacity. Tests can be added, updated, removed, reordered, duplicated, or cleared. Results export to plain TXT 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. Downloads are offered in Default, Blue, and Red themes. One build supports Windows 8, 8.1, 10, and 11; another supports Vista and 7. The download is approximately 470 KB, and the utility has no command-line interface.
