To be honest: RAID controllers are on their way out, a thing of the past. Performance-wise, MD-RAID or ZFS on Linux is faster than doing the same via a RAID controller, while at the same time having far less complexity and failure points. RAID controllers need a prioprietary tool to configure and maintain them, hide your disks behind a single block device and then often make it difficult or impossible to check them, for example via smartd. You have to rely on the proprietary tool to notify you of a disk failure and hope it works and keeps working. I have quite often seen these tools only be availble for ancient Red Hat versions and a pain to get to work on anything else. My advise: Don't bother "learning RAID controllers".
