This article is for you if you don't know how to run the disk speed test on Windows 10. It will explain what disk speed tests do and different ways to run the disk speed test.

What Does Disk Speed Test Scan on Disk on Windows 10?

The disk speed test in Windows 10 also refers to HDD benchmark test. It measures the hard disk's read and write data speed. It uses three main parameters speed, I/O, and delay, to determine a hard disk performance. Below we have explained what is judged and considered best or worst in all three parameters.

1. Speed

It first reads a large amount of data from the disk and measures the time it takes to complete the action to determine read data speed. Then it writes a large amount of data on the hard disk and notes the time it took to complete the process for determining its write data speed.

The read and write data speeds are based on the amount of data and the time it takes to complete the respective process. A higher speed represents a faster hard disk.

2. I/O

I/O or Input/Output metric is based on the number of operations per second (IOPS) a disk can process easily. In simple words, it means how many read and write operations can be performed on the hard disk in a specific period of time. A higher I/O value means the hard disk is able to handle more operations and is in a better state.

3. Delay

Delay or more commonly referred to as latency, is the measure of time a disk takes to respond to a read or write request. The lower delay or latency value means a high-performing hard disk. A higher value indicates a hard disk with serious file system issues.
