NETGEAR ReadyDATA 5200 Software Manual page 22

For example, a RAID 6 set that has been expanded twice by the addition of two RAID
groups goes from RAID 6+ to RAID 6+0, 2x, and then to RAID 6+0, 3x.
- An expanded RAID 10 set is indicated in the same way as a new RAID 10 set:
RAID 1+0.
The following table explains the RAID nomenclature. The sequential expansion number is
indicated by n, and x just indicates times (for example, 2x is two times).
