Agreed. But how long does the process 
- backup
- build new RAID with more disks
- restore
take on the same storage? It's not that much faster, and during the time 
of RAID setup you can't work, if you are very serious about your data. 
Yes, you can build a raid in background and already move data into it, 
but you're not secured during that time. I don't take that risk.
