Disk Bench

What Disk Bench is

Disk Bench is a Windows utility for measuring disk performance through file operations rather than synthetic benchmarks. Its copy test times a file transfer between locations and then deletes the destination file. The Create File test writes a file using a repeated 128-byte string, which Nodesoft describes as appropriate when a computer has one hard disk. Because the program saves files through the current filesystem, fragmentation can affect results as it can during ordinary file use.

Command-line options provide additional tests and logging: copying all files from a source directory, reading multiple files in parallel with a configurable block size, and creating files in parallel with configurable block size and block count. Disk Bench requires Microsoft .NET Framework. It has no installation kit, and Nodesoft says it tests its programs only on Windows 10 and 11. The program is completely free and has command-line support.
