How to Test the Speed of Your M.2 SSD on Windows: 3 Free and Proven Methods

Adding an SSD can speed up your system significantly. However, if you don't monitor the disk's health and fix issues promptly, your system speed will degrade. Thus, you must check your computer's hard drive speed regularly. If you have an M.2 SSD and don't know how to test M.2 SSD speed, this article will guide you.

Yes, you can test the speed of your M.2 SSD. Here's how to do it: 1. **下载基准测试工具**： - You can use tools like CrystalDiskMark, AS SSD Benchmark, or HD Tune Pro for this purpose. Download the one that suits you best. 2. **安装并运行软件**： - After downloading, install the software on your computer. - Launch the benchmarking tool. 3. **选择驱动器**： - In the software interface, select your M.2 SSD from the list of available drives. 4. **配置测试设置**： - Depending on the tool, you might have options to choose the test type (read, write, or both), test size (e.g., 512KB, 4KB, or custom), and other settings. Default settings usually work fine for a basic test. 5. **开始测试**： - Click on the "Start" or "Run" button to initiate the speed test. 6. **查看结果**： - The tool will display the read and write speeds of your SSD in MB/s or MB per second. Make sure to note down these figures for reference. 7. **分析结果**： - Compare the results with the manufacturer's claimed specifications to see if your SSD is performing as expected. Remember, actual performance may vary depending on your system configuration and the specific workload you're testing. If you encounter significantly lower speeds than advertised, it could be due to various factors such as the M.2 interface (PCIe Gen3 vs. PCIe Gen4), controller, or the quality of the SSD itself.

Yes, you can easily test the speed of your M.2 on a Windows computer. There are several built-in and third-party tools to test the speed of a computer's hard drive. Through these methods, you can check the speed of your M.2, NVMe, SSD, HDD, USB, or any external disk. Why would you need to test the speed of your M.2 SSD? Here are some situations where checking your disk speed can be beneficial:

• Freezing Screen: If your computer screen frequently freezes or lags, it might indicate a slow hard drive. Checking the M.2 speed can confirm if this is the root cause.
• Slow Boot Times: A lengthy boot-up time suggests a slow boot drive. If your M.2 drive is the system's boot drive, you should test its speed to uncover potential issues.
• Slow File Transfers: As one of the fastest hard drives, an M.2 SSD should not cause sluggish data transfers. If you experience slow file movement, it's evident that the drive's speed is compromised.
• Poor Software Performance: When an M.2 drive slows down, software performance will suffer. You may notice crashes, freezing, and breakdowns impacting your workflow.
• Game Lag: Are you experiencing lag, bugs, and screen latency in games despite using an M.2 SSD? This points to significant speed issues with your drive. Testing the M.2 speed can help identify underlying problems.
• System Crashes: If the M.2 drive can't handle system loads due to lower speeds, your system might start crashing. Frequent crashes warrant testing the M.2 speed before the drive becomes irreparably damaged.
