DiskSpd

DiskSpd is a tool used to measure the performance of storage devices like hard drives and SSDs. It runs tests that simulate different types of data workloads to evaluate how fast data can be read from or written to the storage. By analyzing results such as speed, latency, and input/output operations per second, DiskSpd helps IT professionals understand a storage device's capabilities, identify bottlenecks, and optimize system performance. It’s a valuable utility for testing and benchmarking storage systems in a controlled, repeatable way.
