The Pro has a much more powerful CPU (Intel Pentium dual-core @ 1.83 GHz) vs. the old sparc-based CPU on the NV. It also has 6-bays vs. 4-bays. In a nutshell, the Pro can read & write at over 100 MB/s, while the NV is around 25-35 MB/s.

In addition to the drives, the Pro has a more powerful CPU than the NVX (1.83 GHz dual-core vs. 1.06 GHz Intel Tolapai SoC). I've got both a Pro and NVX and the Pro has significantly more horsepower and can deliver quite a bit more throughput. Have a look at this document to see the typical performance expectations: http://home.bott.ca/webserver/?p=363

I think it's primarily due to the fact that home users are starting to run into storage issues and are looking for a good way to safely store their digital media. The new Ultra line was designed using the Atom chipset and offers a 2-bay, 4-bay and 6-bay option without the business options of Active Directory, SNMP, ethernet teaming, rsync-over-SSH, 5-yr. warranty, etc.
