External storage for iPhone

[almalino]

What is the good external storage for the iPhone that does not require a computer in between?

My requirements are:

1. 2 TB
2. External (obviously
3. Does not require computer to access it
4. Size could be from portable HDD to small stationary NAS
5. Connection wireless or wired - both are ok
6. Mobility: It could be mobile with battery or stationary. Both options considered.

So far I found Lacie Fuel 2 TB mobile Wi Fi harddrive that looks like a good option but people think UI sux on that.

What are my options?
