Comment Comment by eddythompson80 unRAID is geared towards homelab style deployments. Its main advantages over typical RAID is it's flexibility (https://www.snapraid.it/compare):- It lets you throw JBODs (of ANY size) and you can create a "RAID" over them.- The biggest drive must be a parity drive(s).- N parity = surviving N drive failures.- You can expand your storage pool 1 drive at a time. You need to recalculate parity for the full array.The actual data is spread across drives. If a drive fails, you rebuild it from the parity. This is another implementation (using MergerFS + SnapRAID) https://perfectmediaserver.com/02-tech-stack/snapraid/It's a very simple model to think of compared to something like ZFS. You can add/remove capacity AND protection as you go.Its perf is significantly less than ZFS of course. parent eddythompson80 1 year ago
