DiskBoard

What DiskBoard is

DiskBoard is a free drive utility for benchmarking storage and checking drive-reported S.M.A.R.T. health on Windows and macOS. It runs sequential and random read/write tests, with adjustable file size, buffer size, thread count, and access pattern; live graphs show results as tests run. Health details can include temperature, wear, and reallocated sectors for internal, external, and USB drives. Some USB bridge chips block S.M.A.R.T. commands, so health details may not be available for every USB drive. Users can upload benchmark results to compare with the same drive model or browse rankings of drives. DiskBoard cautions that vendor RAM cache utilities can make benchmark results appear higher than they are, and excludes ranking results that fail its physical-limit check. Windows support is listed for Windows 10 and later, with an x64 build for Intel and AMD chips. macOS support starts at 10.14, with a universal build for Intel and Apple silicon. Windows installation is available through the Microsoft Store or an MSI; macOS users can download the app or install it with Homebrew. Futonica develops DiskBoard and says it is built with bgfx and smartmontools.
