System Requirements

Before embarking on your drive benchmarking journey, ensure that your system meets the following requirements:

  • Operating System: CrystalDiskMark supports Windows XP, Vista, 7, 8, 8.1, 10, as well as Windows Server 2003, 2008, 2012, 2016, and 2019.
  • Architecture: It’s compatible with x86, x64, and ARM64 systems.
  • Administrator Privileges: Notably, the installation process does not support Windows XP/2003 (NT5.x), Windows 95/98/Me/NT4/2000, or Server Core. For testing network drives, run CrystalDiskMark under a standard user account (UAC: No).

Critical Insights

Here are some crucial points to keep in mind when using CrystalDiskMark:

  • Results Variation: Different versions of CrystalDiskMark may yield varying measurement results.
  • Measurement Units: “MB/s” represents one million bytes per second.
  • Varied Results: The test results can vary depending on factors like test data size, location, fragmentation, drive controllers (IDE/PATA, SATA, RAID, SCSI, NVMe), and CPU speed.
  • Data Dependency: A portion of the hard drive’s performance is influenced by the test data, whether random or full.
  • Network Drive Testing: To measure network drives, avoid running CrystalDiskMark with administrator privileges. The UAC dialog provides options for admin and non-admin executions.
