Easiest RAID configuration to recover data if ReadyNAS fails
Hello, I have a ReadyNAS 104 and am not able to buy another quickly if mine fails someday (the NAS, not the drives), because I live in Brazil and hardware of this type here is prohibitely expensive...
Your volume size is exactly right. The rule for estimated volume size on RAID-6 is (a) sum up the disks (b) subtract off the two largest. You are basically wasting 5.4 TB of space. Keep in mind that the NAS reports TiB, not TB, and that there is some filesystem overhead. That's why you aren't seeing a 640 GB size.
The data is distributed so that the system can reconstruct the data on any pair of disks. Though you can test this be removing two drives, generally I wouldn't recommend it. The array would be rebuilt when you reinsert them (though the data is maintained).
