I have 6 RAID6 Thucus 5200 NAS's. They are quite good, reliable, easy to 
manage and so forth but once you have fill the 6 disks, you need another 
NAS. I did replace 6 1TB disks in two of them with 1.5TB disks, but that 
is the biggest size disk they can take, and realistically I would have 
to buy more and more NAS's with time. A better option might be a DIYS 
NAS if your data will only go up and up as you will save money in the 
long run. One thing you might want to look at is ZFS which will let you 
add more and more space to each pool. Yes I think you need 4 disks with 
RAID6 since it can take a 2 disk failure.
