When the I/O performance of your hard is not adequate, your device will boot slowly, lag while doing multiple tasks, and load programs slower than before. This article aims to assist Windows users in determining the Disk I/O test Windows, recognizing disk performance issues, and using I/O testing tools.

Follow this guide to learn how to apply practical methods to detect your disk's I/O performance efficiently. Also, don't forget to share this tutorial online to help more of your friends monitor their disk performance with ease:

How to Run Disk I/O Test on Windows [Two Ways]

This section comprehends two useful tools that are designed for testing the performance of hard drives and SSD drives in Windows computers:

✅Way 1. Run Disk I/O Test via EaseUS Partition Master

✅Way 2. Run Disk I/O Test via Performance Monitor

The first solution is a professional tool to manage disks and partitions. Let's look at how it works.

Way 1. Run Disk I/O Test Software -  EaseUS Partition Master

EaseUS Partition Master is an easy-to-use and secure tool for performing disk I/O tests. It is a convenient program that provides versatile features to analyze and ensure optimal performance of hard disks. Its DiskMark feature is one of the crucial offerings of this tool and provides users with precise and accurate results of disk i/o tests.

Moreover, EaseUS disk i/o disk test software - Partition Master is compatible with all Windows versions, so you should not miss it, especially if you are a non-tech savvy user looking for a quick solution. 

Download EaseUS Partition Master and follow the steps to run the Disk I/O Test on Windows.

Step 1. Launch EaseUS Partition Master. And click the download button to activate the "DiskMark" feature under the "Discovery" section.

Step 2. Click on the drop-down box to choose the target drive, test data, and block size.

Step 3. Once everything is configured, click "Start" to begin the disk test. Then, you can see the Sequential or Random read/write speed, I/O, and Delay data.

With this tool, you can test hard drive speed easily and quickly. The features of EaseUS Partition Master cover most aspects of disks and partitions.

If you encounter any partition errors, you can use EaseUS Partition Master to fix them:

Way 2. Run Disk I/O Test via Performance Monitor

You can get a general overview of the current workload of I/O using the Performance Monitor. It is a built-in Windows Utility to facilitate users estimating the current disk input/output performing. Execute the following steps and use the Perfmon counter to monitor disk I/O on Windows.

Step 1: Press the Windows button, type Perfmon and click Run as Administrative. 

Step 2: On the left-side panel, find the Performance section. 

Step 3: Click Data Collector Sets, and choose User Defined.

Step 4: Right-click on User Define, select New and Data Collector Set.

Step 5: Type your desired name (i.e., Test 1), and select Create manually (Advanced).

Step 6: Click Next, and select the Performance Counter option under Create Data Logs.

Step 7: Select Finish.

Note* The data set (Test 1) will appear in the right panel.

Step 8: Double-click the data set and check if the DataCollector01 appears. 

Step 9: Double-click on the DateCollector01 and select Add.

Step 10: Find and select PhysicalDisk from the list of available counters.

Step 11: Select the counters you need to check:

• % Disk Read Time 
• % Disk Time 
• % Disk Write Time
• % Idle Time 
• Current Disk Queue Length
• Disk Peads/sec
• Disk Writes/sec
• Split IO/sec

Step 12: Click Add and close the "Add Counters" window.

Step 13: Set the "Sample interval" to 30 seconds in the "Performance Counters" window again, then click "Next."

Step 14: Choose a location to save the performance log file.

And then, you can start capturing I/O data using the new Data Collector Set.

Step 15: Expand Performance > Data Collector Sets > User Defined > {report name}

Step 16: Right-click the report name and select "Start".

Step 17: After capturing the data, right-click the report and click "Stop."

As you can see, this process is pretty complicated. If you are unfamiliar with this tool, EaseUS Partition Master is your best choice to check disk and can give you a more precise result. Also, don't forget to share the above two methods online to help more of your friends monitor their disk i/o performance efficiently:

What Is Disk I/O on Windows 

In general terms, I/O refers to the input/output functions of the physical disk in your computer. The process of I/O includes every characteristic that involves in the read-and-write process of the hard drive. During maintenance time or while running heavy programs, the rate of I/O may run high and put a heavy load on the disk's performance.

Furthermore, An HDD's I/O operations are significantly slower than those for solid-state memory, such as RAM. On average, HDD I/O processes take 2,000 times longer than RAM. I/O issues of storage drives are usually more difficult to troubleshoot as they are embodied in the memory or CPU. To avoid disk performance issues, you should regularly test the Disk's I/O using the correct tools. You should also pay attention to the following signs of the common performance issues of your disk:

• There is a high I/O at peak times or during maintenance.
• Write or read requests take longer while using multiple programs.
• Queries slow down due to memory pressure.
• The database server is being slowed down by CPU pressure.
• Concurrency issues from locking/blocking.

Conclusion

After effectively testing the I/O disk performance, you can take action to counter possible performance issues and reduce the risk of unexpected disk failure. We highly recommend you look at EaseUS Partition Master, as you might get confused testing I/O with Windows Performance Monitor. 

FAQs About Disk I/O Test on Windows

See our Frequently Asked Questions section for more questions about the disk I/O test on Windows.

1. How do I monitor disk I/O on Windows?

In Windows, you have two ways to monitor disk I/O test. But it's complicated to use Performance Monitor to do this. Instead, you can use EaseUS Partition Master to do this.

Step 1. Launch EaseUS Partition Master and click "DiskMark" under the "Discovery" section.

Step 2. Select the drive, test data, and clock size.

Step 3. Click "Start" and wait a while to see the speed and I/O data.

2. How do I fix the hard disk I/O error?

Here are some quick fixes to repair the hard disk i/o error:

• Restart your computer/Laptop
• Try to reaccess the drive/device
• Run CHKDSK
• Update the Device Driver
• Check Disk health

To repair the errors, you can use EaseUS Partition Master to help you.

3. What is a good IOPS for SSD?

For an SSD, we suggest 256 gigs. If you have a 128-gigabyte drive, it will work fine. However, if you're planning on gaming or downloading a lot, we suggest at least a 250 GB drive.
