Collected common questions and answers during users' use of CrystalDiskMark to help you quickly solve problems encountered during use
A1: First, close other programs that occupy the hard drive (such as download tools, video players, antivirus software, etc.) to ensure the hard drive is idle during testing; second, it is recommended to run CrystalDiskMark as an administrator; finally, take the average value of multiple tests to avoid the randomness of a single test. In addition, do not perform disk defragmentation and other operations before testing to avoid affecting test results.
A2: CrystalDiskMark supports testing all storage devices recognizable by Windows, including mechanical hard drives (HDD), solid-state drives (SSD), NVMe protocol solid-state drives, mobile hard drives, U disks, memory cards, etc., and can accurately test the read/write speeds and performance of various storage devices.
A3: Right-click the CrystalDiskMark program icon and select "Run as administrator" to solve the insufficient permissions problem. Administrator privileges allow CrystalDiskMark to better access and test all hard drive devices, avoiding the problem that some hard drives cannot be tested or test results are abnormal due to permission issues.
A4: CrystalDiskMark is a green portable software that can be run immediately after downloading and decompressing without installing to the system disk. It is recommended to save the decompressed folder to a fixed location for easy subsequent use. At the same time, the portable feature avoids modifying the system registry and is safer to use.
A5: 4K read/write refers to the random read/write speed of the hard drive for 4KB size files, which is an important indicator to measure hard drive performance. Especially for the system disk, 4K read/write speed directly affects system response speed, software startup speed and file copy speed. The 4K read/write speed of SSD is much higher than that of traditional HDD, which is the main reason why SSD runs more smoothly.
Detailed CrystalDiskMark usage steps to help you quickly master hard drive speed testing methods and obtain accurate hard drive performance data
Download the compressed package of the corresponding version of CrystalDiskMark from this website, and decompress it to any folder using decompression software (such as WinRAR, 7-Zip) without installation.
Note: It is recommended to decompress to a non-system disk to avoid affecting test results due to file reading and writing when testing the system disk.
Open the decompressed folder, find the CrystalDiskMark.exe file, right-click and select "Run as administrator" (recommended), and the main interface will be displayed after the program starts.
It may be blocked by antivirus software for the first run, select "Allow to run" and CrystalDiskMark is a safe and non-toxic green software.
Select the hard drive to be tested (such as C drive, D drive) from the drop-down menu at the top of the CrystalDiskMark main interface. The default parameters are suitable for most users and do not need to be modified.
Professional users can customize test block size, test times, queue depth and other parameters to meet personalized test needs.
Click the "All" button on the interface to start a comprehensive test. The program will test sequential read/write, random read/write and other items in turn. Do not operate the computer during the test to avoid affecting test results.
After the test is completed, the interface will display various test data, including read/write speeds of Seq Q8T1, Seq Q1T1, 4K Q8T1, 4K Q1T1 and other items.
After the test is completed, you can view various data: Seq represents sequential read/write speed, 4K represents random read/write speed, and higher values indicate better hard drive performance.
Click the "Copy" button on the interface to copy test results, or click the "Save" button to export results as text/HTML files for easy saving and sharing.
