    RAID always working since Catalina

    Ever since installing Catalina, I've noticed that my RAID is constantly working. It never stops. The data seems fine and the drives aren't reporting any issues.

    RAID question: Adding Bigger Hard Drives to a RAID1 Setup

    I’ve been using a RAID 1 setup with 2x 4TB drives. I’m about to run out of room and purchased 2 8TB drives to upgrade the available space. What’s the best way to do this while maintaining the same data on the drives? Can I pull one 4TB drive and replace it with an 8TB, then let it rebuild and...
