What is CrystalDiskInfo?
CrystalDiskInfo brings a drive's health status, temperature and hardware details into one Windows utility. Use it to inspect a supported HDD or SSD, read its S.M.A.R.T. attributes and check details such as firmware, power-on count and power-on hours. Graphs show changes in S.M.A.R.T. information, while resident monitoring and alarms help flag conditions that need attention.
Drive visibility depends on the controller and connection. USB and RAID support is partial, and external enclosures holding multiple drives are often unsupported. NVMe monitoring requires Windows 10 or Windows Server 2016 or later.
The download is the Standard Edition ZIP archive, not an installer. Extract it into a folder before use. The publisher lists x86, x64 and ARM64 support; its older Windows compatibility does not extend NVMe support to those older systems.
