My current home lab had 2x4tb drives in Raid 1. Today’s goal is converting to Raid 5 and adding 4x4tb drives to expand storage without losing data. THIS IS NOT A GUIDE, unless it works.

Just so I’m clear on this, is “raid controller” a physical device? Real servers are like wizard magic to me.
They can be. Some motherboards come with one built in. But in most cases it refers to its own PCIe card, such as one of the many models from LSI Megaraid.
The advantage of this is that it can have a small capacitor bank (or a proper battery) to provide emergency power so that if something stupid happens such as motherboard failure, the raid controller will use this power to cleanly write to the disks.
