I’ll show how to test the read/write speed of a disk from the Linux command line using dd command. I’ll also show how to install and use hdparm utility for measuring read speed of a disk on Linux Mint, Ubuntu, Debian, CentOS, RHEL. Use dd command to monitor the reading and writing performance of a disk device: Open a shell prompt. Or login to a remote server via ssh. Use the dd command to measure server throughput (write speed): # dd if=/dev/zero . If you want to monitor the disk read and write speed in real-time you can use the iotop tool.

The purpose of this tutorial is to describe some simple hard drive speed tests that you can perform using your Linux system and the command line tool hdparm. hdparm tool is an easy to use tool to quickly assess your hard drive’s speed.When performing speed tests, hdparm disregards the file system currently in use and writes to the raw device instead.
The results in hdparm show that our USB drive gets 19.64 MB/sec read speed; USB benchmark test with Bonnie++. Bonnie++ will perform a thorough test to determine the read and write speed of our USB storage device. This will give you a very accurate result, but it will take much longer to perform the test when compared to hdparm.. Get started by installing .
Explore essential tools and techniques to measure read and write speeds for enhanced system efficiency. . You can use this tutorial to test Linux hard drive speed for various reasons, such as evaluating your PC storage device or determining whether your VPS provider genuinely provides SSD storage as promised.
Clearing the buffer ensures that the read test we’ll be conducting later will read the file from the disk, not the buffer. Once we’ve cleared the buffer cache, we can run a test of the read speed using the dd command again. For the sequential read speed test, we’ll read from the /tmp/tempfile and write it to the /dev/null pseudo device file:
Not always. I was recently testing a disk in exactly the same way and /dev/zero tricked me into thinking I had the performance I needed because the external disk was using NTFS disk compression.At first I tried using /dev/urandom to fix this problem, but I discovered that tricked me into thinking that things were going too slowly. If you want to do this without being . HTML 5 Video 01: Running Disks on Ubuntu to test SSD read and write speed.

After that, we can test the read speed (without using the cache) of the hard disk sda with the following command: hdparm -tT --direct /dev/sda. Alternatively, we can also test the write speed with a test file. To do this, we first need to .This example slows drive reading speed ninefold. Write-Back Caching. With write-back caching, the hard drive first stores the data to be written in a buffer. In this way, it can accept data much faster, which in the end leads to a faster write speed.
