What Disk Bench is

Disk Bench is a free Windows utility that measures disk performance through file operations rather than synthetic benchmarks. Its copy test transfers a file to another location, times the operation, and deletes the destination copy afterward. The Create File test writes a file made from a repeated 128 byte string, which the maker describes as optimal when there is only one hard disk. Because the program saves files through the current filesystem, fragmentation can affect performance as it does in ordinary file use. Command-line options can copy all files from a source directory to a destination and log the result, read multiple files in parallel with a configurable block size, or create files in parallel with configurable block size and number of blocks. Command-line options for Read File and Create File were added in version 2.8.0.1 to support automation. Disk Bench requires Microsoft .NET Framework. Nodesoft says it tests its programs only on Windows 10 and 11, and does not provide an installation kit. The maker invites users to email suggestions and feedback about its free tools.
