I’ve been running Unraid for a while now, and my single 128GB cache drive—formatted XFS—was starting to feel cramped. I picked up two shiny 512GB drives and decided to replace the old one with a BTRFS mirror. The goal was simple: keep the mount point at /mnt/cache so all my shares, Docker containers, and VMs would just… keep working. Seamless. Invisible. Easy, right?
SSD prices are insanely low right now—but manufacturers focused on bottom line have built computers designed to prevent consumers from leveraging this trend.
