Hi
Can you please explain the difference between x-raid and flex-raid
XRAID is a simple RAID management method that will automatically create a suitable RAID mode for you, and which will also automatically expand your RAID array when you add disks (horizontal expansion) or replace disks with larger ones (vertical expansion). It is limited to a single volume.
FlexRAID is a more sophisticated management method which gives you a lot more control over your RAID setup. It also lets you set up RAID modes that XRAID doesn't support. If you want multiple RAID volumes in your ReadyNAS, you will need to use FlexRAID.
Both FlexRAID and XRAID use the same linux tools for software RAID. The Web UI will let you switch back and forth as long as your FlexRAID settings are compatible with XRAID.
In your case, once you set up RAID-6 in FlexRAID you can switch back to XRAID and the system will then maintain dual redundancy (protection from two disk failures). If you want to vertically expand, you will need to replace 4 disks with the larger size before expansion can occur.
The software manual has more information on this.
