Media Streaming and Power Consumption (Pro6 vs Ultra6Plus)

The Pro 6 (RNDP6000-200) is a business product whilst the Ultra 6 (RNDU6000) and Ultra 6 Plus (RNDP600U-200) are home products for the prosumer. Business features (only available on business products) tend to get advertised in manuals etc for business products whilst media streaming features get advertised for home products. So both the manuals and comparison chart are correct. The Pro 6 has all the media streaming features of the other products either pre-installed or available via addons (which can simply be installed by Add-ons > Add new in Frontview - web-interface of the ReadyNAS).

The Pro 6 has a faster CPU than the Ultra 6 Plus. See CPU Specs of the ReadyNAS. Testing has shown that if you want to transcode (convert on the fly) 1080p HD video (e.g. to stream to a mobile device such as an iPad) then you'll need a Pro 6.

The Pro 6 has a 5 year warranty and business features and faster performance (due to faster CPU), so I would go with the Pro 6.

I think it's the Ultra 6 (has Atom CPU) that's supposed to have lower power consumption, but the Atom CPU is much slower than the Pentium CPUs in the Ultra 6 Plus and Pro 6.
