Upgrade to Ultra 4 Plus, Max storage capacity

Thank you for the informational replies. Stephen B, If I am understanding you correctly (regarding max expansion capacity to 14TB) if I load up all four 2TB drives now and do a drive wipe I will get 6TB capacity with the ability to remove those four 2TB drives and replace them with a combination of larger drives totaling 14TB (without having to do another factory default/wipe). Is that correct? If that is the case then I will most likely just buy two more drives and install all four now to maximize storage capacity. I would be good to go for a while with 6TB available space.

Regarding X-RAID, I understand that is the default single drive failure protection configuration. So if I have four drives loaded and one fails I would still retain all my data? I also understand that one drive is for parity information but not really understanding how one drive can protect the information on the three other drives. What if the parity drive fails?

All comments on Link Aggregation are noted. Just wanted to make sure if it was something I should be utilizing. I may have been asking about the wrong feature though. I was wondering why the Ultra 2/4 Plus units have two ethernet ports.

Thank you,
