CrystalDiskMark is an open source disk drive benchmark tool for Microsoft Windows from Crystal Dew World. Based on Microsoft's MIT-licensed Diskspd tool, this graphical benchmark is commonly used for testing the performance of solid-state storage. It works by reading and writing through the filesystem in a volume-dependent way. It generates read/write speeds in sequential and random positions with varying numbers of queues and threads. Solid-state drives tend to excel at random IO, as unlike hard drives, they do not need to seek for the specific position to read from or write to.
There is a macOS clone version of it called AmorphousDiskMark developed by Katsura Shareware, named after the non-crystalline amorphous state of solids.
CrystalDiskInfo is an MIT-licensed S.M.A.R.T. utility for reading and monitoring disk drive status. Like CrystalDiskMark, this tool is designed with an emphasis around solid state devices, supporting NVMe connections in addition to the usual PATA and SATA. Other features include Intel RAID support, e-mail and sound warnings, and AAM/APM adjustment.
