Linux readily has a built-in tool named dd for measuring disk speed, which is particularly efficient for HDDs speed test as the hard drives are commonly used for large sequential writes and read. However, dd and also “hdparm” are two easy-to-use methods to test disk speed in Linux, they only address sequential access patterns.

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 dd utility in Linux offers functionality to measure both read and write speed. The advantage of using the dd command for benchmarking is that it’s straightforward to use with easy-to-interpret result output.The downside, however, is that it can only measure the sequential read and write speed and lacks support for random access metrics. A performance test will put load on your Linux machine and stress test components like the CPU, memory, and hard drive. The stress Linux command is an ideal utility to put load on a computer and push your hardware to its limits. In this tutorial, you will learn how to install and use the stress and stress-ng commands and their various options.

What is S.M.A.R.T.? S.M.A.R.T. –for Self-Monitoring, Analysis, and Reporting Technology— is a technology embedded in storage devices like hard disk drives or SSDs and whose goal is to monitor their health status.. In practice, S.M.A.R.T. will monitor several disk parameters during normal drive operations, like the number of reading errors, the drive . Step 1: Use the lsblk command to get a list of all the system's attached hard disks. Locate the hard drive you want to test by looking through. We'll test /dev/sda in this case. lsblk Copy. Step 2: To start the test, run the hdparm -Tt command on the hard disk; sudo hdparm -Tt /dev/sda Copy. The test results will appear on the screen after it .S.M.A.R.T., which stands for Self-Monitoring, Analysis, and Reporting Technology, is a system used to monitor the health of hard drives.It is built into both traditional HDDs and modern SSDs.The main purpose of S.M.A.R.T. is to help detect potential drive failures by analyzing certain parameters and providing early warnings..
