I have been lucky. I have had very few critical hard drive failures in my life. But as time goes on rolling those dices will be more risky so.. Lets see how hard is to set up RAID array.
In this small write up I will show how to set up RAID6 array with 4 drives.
Hardware that we will use is:
RaspberryPi 3B+
USB HUB
5x USB memory sticks (Any size will work).
Before we start learn from my failures.
