Tool materials:

System version: Windows 11 22H2

Brand model: Lenovo Xiaoxin Pro 16 2022

Software version: CrystalDiskMark 8.0.4

1. Introduction to CrystalDiskMark software

CrystalDiskMark is an excellent hard drive performance testing software that can not only test hard drives, but also U disks, SD cards, etc. Read and write speeds of various storage devices. It is easy to operate, has a clear interface, and the test results are accurate and intuitive. It is an ideal tool for evaluating the performance of storage devices.

CrystalDiskMark supports a variety of test modes, including sequential read and write, 4K random read and write, etc., which can comprehensively evaluate the performance of storage devices in different usage scenarios. At the same time, it also provides a variety of test parameters for users to customize, such as test file size, queue depth, etc., to meet the testing needs of different users.

2. Use CrystalDiskMark to test U disk performance

1. Download and install the CrystalDiskMark software. It is recommended to download the latest version from the official website.

2. Insert the U disk to be tested into the USB port of the computer to ensure that the U disk is correctly recognized.

3. Open the CrystalDiskMark software and select the U disk to be tested in the drop-down menu.

4. Select the test mode and parameters as needed. It is generally recommended to select the sequential read and write and 4K random read and write modes, and set the test file size to 1GiB.

5. Click the "All" button to start the test and wait for the test to complete.

6. After the test is completed, the software will display the reading and writing speed results of the U disk in each test mode. The larger the value, the better the performance.

7. Compare the test results with the U disk’s promotional parameters to evaluate whether the actual performance of the U disk is consistent with the manufacturer’s promotion.

3. How to choose high-quality U disk based on test results

1. Sequential read and write speed: This is an important indicator for evaluating the overall performance of U disk, corresponding to daily large file copy scenarios, speed The higher the better. The sequential read and write speed of high-quality USB flash drives can generally reach more than 100MB/s.

2. 4K random read and write speed: This indicator reflects the U disk’s ability to process small files and multiple files, and corresponds to daily document editing, program running and other usage scenarios. 4K random reading and writing is a shortcoming of U disks, and high-quality U disks can also achieve better results in this indicator.

3. Speed ​​stability: Test the performance of the U disk multiple times and observe the stability of the test results. The test results of high-quality USB flash drives are generally relatively stable and will not fluctuate significantly.

4. Actual capacity: Use a computer to check the actual available capacity of the USB flash drive and compare it with the advertised capacity. The actual capacity of high-quality USB flash drives is not much different from the advertised capacity.

Based on the above indicators, you can buy a high-quality product by choosing a U disk with high sequential read and write and 4K random read and write speeds, good speed stability, and actual capacity consistent with the promotion.

1. Precautions when using U disk: Regularly format the U disk to maintain performance, do not store important and unique data in the U disk to prevent the U disk from Loss or damage results in data loss; click "Eject U Disk" before pulling out the U disk to avoid damaging the U disk or file system.

2. U disk exception handling method: When the U disk cannot be recognized or the file system is damaged, you can try to repair it by replacing the USB interface, identifying it on other computers, reformatting, etc.; if it still cannot be repaired, it is recommended to send it to Repair or replace the USB flash drive with a new one.

Summary:

Purchasing high-quality U disks is not an easy task, but using U disk performance testing tools such as CrystalDiskMark can quickly and comprehensively evaluate the performance of U disks and provide a basis for purchasing high-quality U disks. The USB flash drive provides objective evidence. When testing, you need to focus on indicators such as the sequential read and write speed, 4K random read and write speed, speed stability, and actual capacity of the USB flash drive, and choose products with excellent overall performance. In addition, when using U disks daily, you need to pay attention to details such as regular maintenance, correct ejection, and exception handling to extend the service life of the U disk and improve the use experience.
