==== Why software RAID using MDADM instead of hardware RAID with a RAID controller card? ==== RAID controller cards are for people with datacenters that have hundreds of drives and need maximum performance/resilience for specific applications, that want the task of managing these drives separate from the software running the computer. This was also very useful back when machines were powered by Pentium 1 processors. <blockquote>'''NOTE:''' Some hardware RAID controllers will give you improvements in performance, but itโs not worth the downside. There are controllers where when they fail, you have to replace it with the exact same controller for your setup to work again - aka, digiorno all over again. Using software RAID like MDADM means you can take drives out of a pentium 4 and put them into a macbook and itโll just detect it & work. </blockquote> It is 2024, and even a ten-year-old computer will do software RAID just fine with no perceivable penalty in performance. <span id="why-not-use-raid-built-into-my-motherboard"></span>
