In the question“What are the best single-board computers?” The Parallella Board is ranked 18th while Helios4 is ranked 38th. The most important reason people chose The Parallella Board is:
The Parallella Board makes use of the Epiphany III coprocessor which is invisible to the OS unless directly addressed through its APIs. It currently boasts 32 gigaflops from its 16-core variant with a promise of 100 gigaflops for a 64-core model which will be available in the future.

Question Ranking
Pros
Pro Amazing performance because of the Epiphany coprocessor
The Parallella Board makes use of the Epiphany III coprocessor which is invisible to the OS unless directly addressed through its APIs. It currently boasts 32 gigaflops from its 16-core variant with a promise of 100 gigaflops for a 64-core model which will be available in the future.
Pro Low cost Xilinx Zynq FPGA development
Although not a beefy FPGA, the price is right
Pro Excellent many-core RISC architecture
High performance, energy-efficient floating point capable, general purpose RISC cores
Pro Great board for programmers to experiment on different platforms
The Parallella is a great board for programmers to experiment programmin on ARM, FPGA and the Epiphany architecture in one compact package.
Pro Completely open source
Parallella uses open source hardware. The drivers are released as open source as well. All the details about the board designs and schematics can be found on GitHub.
Pro Ships with open source development tools geared towards Epiphany development
Parallella ships with several open source tools geared towards developing for the Epiphany architecture. Some of these tools include a C compiler, Eclipse, OpenCL SDK/compiler and runtime libraries.
Pro 4 X SATA 3.0
Has four SATA 3.0 ports so it can handle up to 48TB of storage (12TB on each SATA port).
Cons
Con Not great for media streaming
The Parallella board was built to give everyone access to a mini-supercomputer. It's strength lies in the Epiphany which makes it great for parallel computing and image processing, unfortunately it's not good with media (audio and video) streaming.
Con Requires dedicated software development
Since it uses a different architecture than most boards, out-of-the-box software is not compatible with it. Instead, there's a huge GitHub repository with official ports of popular software compatible with the Parallella Board.
Con The project fall down
Con No battery or UPS
A PC tailored for NAS usage should have a battery or UPS to prevent data corruption after a power loss. A tiny battery to safely shut it down would be enough.
Con Company shut down business!
See their website-shop.
Con Expensive
After the preorder It is expensive now.
