D-Bench vs Parkdale

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.

Parkdale measures read and write speeds for hard disks, CD-ROM devices and network servers. Its three access modes offer different ways to run a drive test. QuickAccess checks sequential and random access with 4KB blocks and 32 concurrent threads. FileAccess reads and writes test data in a regular file through the filesystem; BlockAccess works directly with disk sectors and displays transfer rates over time. Users can compare and submit drive results on the Benchmark page. The Windows version has command-line options for the drive, file size, block size and log-file creation, and installation is available through winget and Chocolatey. Parkdale runs on Windows, macOS and Android, with the maker listing operating systems from Windows 11 through Windows 98, macOS 27 through 10.7, and Android 12 through 4.4. The free software is supported by donations. The maker says crash reporting and automatic update checks can be disabled; those functions send a unique non-personal ID and operating-system version, and IP addresses are recorded to distinguish usage countries.
