DiskBoard1.0.8

Measure the real read and write performance of an SSD, NVMe drive, hard disk, or USB stick with DiskBoard’s configurable benchmark. Every connected drive appears as a card showing its bus, capacity, and S.M.A.R.T. health state, giving Mac users one place to inspect storage hardware. Select a drive, choose a quick everyday check or a longer stress run, and read the outcome from a gauge and live graphs.

The benchmark covers sequential and random reads and writes, with controls for file size, buffer size, thread count, and access pattern so the workload can reflect how the drive is used. Graphs display operations as they happen and include SATA, USB, and NVMe reference lines for interpreting the result. Its health view reports temperature, wear, reallocated sectors, and every other S.M.A.R.T. attribute provided by internal, external, and USB devices.

A one-click upload adds a result to DiskBoard’s community rankings, where it can be compared with the same drive model in other machines or used to browse the fastest drives on the board. It fits users checking a new storage device, diagnosing sluggish performance, or monitoring an aging disk, as well as anyone comparing hardware results across systems. The freeware utility is available for macOS and Windows; the macOS version supports Intel and Apple Silicon, and the current release is version 1.0.8.
