![]() The other one is “Start Read/Write Benchmark” and it measures the speed of both I/O operations, which is bound to be slower. The first one is “Start Read-Only Benchmark” and it does just what it says: measure how fast your disk is when just reading from it. On the new screen with the chart, you’ll find two buttons. On the Disk Utility’s right panel, find and click on the ”Benchmark – Measure Drive Performance” button to start Benchmark up. Select the one you want to test by clicking on it. On the left panel, you’ll see a list of all the disks available on your computer. You can easily open the Disk Utility by entering the application menu and searching for “Disk” or by finding it in the menu under System → Administration → Disk Utility Step 2: Select the disk for the test Here, we’re going to use Ubuntu 21 as an example, but most Linux distros have the same utility. You can also use the native Linux Disk utility to perform disk speed tests without entering commands into the Terminal. Get your Linux VPS Linux Disk Speed Test Using the Graphical Method Want a better way to host your websites and web apps? Developing something new? Simply don’t like Windows? That’s why we have Linux VPS. To do that for our HDD, we will need to type in “seqread” and “seqwrite” for – – readwrite. The advantage of “fio” is that you can go for sequential reads and writes tests as well. Overall, an SSD outperforms an HDD in random access usage and that is why it is more recommended. This random write speed test on HDD shows weaker performance than that of an SSD. ![]() Now let’s run the exact same commands for an HDD: Let’s first run a basic test with the following specifications:ĭata volume: 250MB, Reads: 80% of the whole data, Write: 20% of the whole dataīlock Size: 4k, Disk: SSD, Performance Indicators: IOPS and MB/s, Type of test: Random read/write To install this utility: sudo apt-get install fio Step 2: Run an SSD Disk Speed Test “fio”, which is not available on Linux by default, can be installed easily nonetheless. IOPS is just the same MB/s multiplied by BlockSize/1024, i.e. In this method, IOPS (Input/Output operations Per Second) is introduced for the sake of convenience. Please note that speed is basically calculated in MBps. To overcome this shortcoming, “fio” has been developed.Īlso Read: What is Linux bashrc and How to Use It? This unqualifies sequential-based methods from estimating the real-world write/read speed of a disk. In practice, read/write interaction with the disk more often than not follows a random access pattern. The previous benchmarks only account for sequential read/write speed tests. Run the hdparm utility by entering the command below into the Linux Terminal sudo hdparm -Tt/dev/sda To install “hdparm” on Mint, Ubuntu, Debian: sudo apt-get install hdparm Step 2: Run hdparm To install “hdparm” on CentOS, RHEL distributions: sudo yum install hdparm Step 1: Install hdparmįirst, you need to install “hdparm” on your Linux, and following that you may run a command to get a digit as the reading speed of the disk. “hdparm” is another Linux command-line tool that can be used to derive a sequential read speed of a storage device. ![]() Yet, the final result is far off the experience a user might have with the disk.Īlso Read: How to delete a directory in Linux? Test your HDD, SSD Read Speed using Hdparm ![]() To extract a better result, you can calculate the average of 4 measurements. If you run the above commands repeatedly, you will see different results. To obtain a single digit as Write speed of the disk, you are supposed to run the following command and the output will look like the one in the picture below.Īlso, you may use the two following commands to first delete the cached-in temporary file created in a buffer by our previous command, and then to measure the Read speed of the disk. Test Disk Speed in Linux using ddĭd is a Linux built-in tool and can be used to generally indicate how much time it takes to complete an operation. Well, there are multiple approaches to do this and you can use any of them. Get your Linux VPS Test disk speed in Linux using commands ![]()
