How to Check the Read and Write Speed of HDD, SSD, USB Drives with

This guide explains how to check the Read and Write Speed of HDD, SSD, USB Drives with, with clear steps, practical tips, and important checks before you begin.

First of all you need to download and install the CrystalDiskMark software on your computer.

After downloading, you proceed to install normally, the installation software is very simple.

Once installed, launch the program and select the drive to test the speed, for example here we will check the speed of the C drive, which is an SSD:

Here we have 4 methods to measure hard drive speed, you can choose 1 of 4 modes or click All to check with all 4 modes.

Now wait for a while for the test to take place, which may take 5 or 10 minutes.

And after some time we have the results of checking the read and write speed of the hard drive:

Of the results that interest you the most is the Seq test mode, you can see that the read speed of the hard drive is 463.9 MB / s and the write speed is 232.0 MB / s, the speed is quite good.

In addition, you can also refer to the meaning of other test modes as follows:

• Seq Q32T1 : The data is read sequentially and sequentially to the vicinity of the drive with 32 rows (Queues) and 1 thread (Threads) of data. This test mode will give the fastest speed.
• 4KiB Q8T8 : The data is randomly read and written on the data area. Queues = 8, Threads = 8.
• 4KiB Q32T1 : The data is randomly read and written on the data area. Queues = 32, Threads = 1.
• 4KiB Q1T1: The data is randomly read and written on the data area. Queues = 1, Threads = 1.

Above is an instruction on how to check the read and write speed of HDD, SSD, USB with CrystalDiskMark software. Hope you will find the article useful, wish you success!
