Disk Speed Test (Read/Write): HDD, SSD Performance in Linux

From this article you’ll learn how to measure an input/output performance of a file system on such devices as HDD, SSD, USB Flash Drive etc.

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.

Take the average result: To get the accurate read/write speed, you should repeat the below tests several times (usually 3-5) and take the average result.

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

This is mostly for my own benefit when I invariably format a computer using these adapters and forget how to get wifi working again:

• TP-Link T2U Nano (AC600)¹
• TP-Link T3U Plus (AC1300)¹

Plug device in and ensure it is detected via lsusb:

For the T3U Plus, the ID is 2357:0138.
