Frequently asked questions about CrystalDiskMark (hard disk detection tool)

1. CrystalDiskMark detects hard drives. What do these lines of data represent?

The first line represents your current test hard disk partition.

The second line represents youhard drivereading and writing speed.

The third line represents the multi-threaded reading and writing speed of 4K files on your hard disk.

The fourth line represents the continuous read and write speed of your hard drive.

The fifth line represents the single-thread reading and writing speed of 4K small files on your hard disk.

2. Use crystaldiskmark to test the hard drivedataPlease explain, is the hard drive normal?

Generally speaking, just look at the first line, Seq, which is the sustained transfer rate. Is it a laptop hard drive or a desktop hard drive? The reading speed of 100M is not bad if it is a laptop hard drive, but it is low if it is a desktop hard drive.

The subsequent test is the reading and writing speed of small files. For mechanical hard drives, reading and writing small files will involve a large amount of head seek time, so the reading and writing speed will decrease. The smaller the file, the greater the drop. This is normal.

CrystalDiskMark (hard disk detection tool) software features

Lightweight, portable and easy to operate

No installation is required, the green version runs directly, and the interface is simple and intuitive, suitable for novices to get started quickly.

Supports multiple languages ​​(including Chinese), and users can customize themes and interface skins.

Multiple scenario test coverage

Provides sequential read and write (SEQ), random read and write (RND) tests, data block sizes cover 4KB, 128KB, 1MB, etc., simulating different application scenarios (such as frequent access to small files, large file transfer).

Supports queue depth (QD) and thread number (T) adjustment, which can simulate high concurrent loads (such as QD32T16 extreme test).

High accuracy and compatibility

The test results are displayed in four units: MB/s, GB/s, IOPS, and Latency. The data is accurate and reliable.

Compatible with storage devices such as mechanical hard disks (HDD), solid state drives (SSD, including NVMe/SATA interface), USB flash drives.

Rich additional functions

Supports saving test results as pictures or text files for easy sharing and analysis.

It can read hard drive SMART information (such as temperature, usage time, power-on times) to assist in determining the health status of the hard drive.

CrystalDiskMark (hard drive checkTest tool) function introduction

In the CrystalDiskMark interface, you can select the number of tests, the test file size and the test object. Click the buttons in the lower row to perform a single file read and write test or multiple small file read and write tests of 512kb or 4kb. In fact, this kind of software is of no use to the hard disk. I keep it in the computer to test the speed of the USB flash drive. Friends in need can try the reading and writing speed of their own USB flash drive. According to what is said online:

Performance testing

Supports sequential read and write (continuous large file transfer speed) and random read and write (small file fragmentation processing capabilities) tests.

Customizable test file size (such as 1GB, 8GB), queue depth (simulating multi-task concurrency).

Multiple interface support

Compatible with SATA, NVMe, USB and other storage devices, covering solid state drives (SSD), mechanical hard drives (HDD), USB flash drives, etc.

Multi-mode detection

Provides different block size tests such as 512 bytes, 4KB, 64KB, etc. to evaluate the device's processing efficiency of different data blocks.

Results visualization

Generate histogram/table reports to visually compare parameters such as read/write speed, response time, etc.

System compatibility

Supports Windows, macOS, and Linux systems, and has a portable version that requires no installation.

Extended functions

Supports full disk wipe (securely erase SSD data), cache test (verify the effectiveness of the device cache mechanism).

How to use CrystalDiskMark (hard disk detection tool)

The specific usage is as follows:

Seq: Continuously perform read and write hard disk detection (1024K bytes)

512K: Randomly perform read and write hard disk detection (512K bytes)

4K: Randomly perform read and write hard disk detection (4K bytes)

4K QD32: Random read and write detection for NCQ and AHCI modes (4K bytes, queue depth 32)

2. Click "All" to detect all items.
