You can run an OS on flash memory, but you will have to replace it  
eventually; it's not about "failure rate" with flash memory so much as  
failure time, because all flash memory has a definite number of writes that  
can be performed on it. Intelligent wear leveling tries to maximize this  
number, but it is literally impossible to use the same flash memory forever,  
unlike a hard drive which does tend to fail after some time but theoretically  
can last forever in the right conditions.

Anyway, because of this, I would recommend using a microSD card for the OS  
rather than the NAND, regardless of how reliable it is. Just use the NAND for  
a backup OS, or for extra storage, or even as a shim for booting the drive  
that really has the OS on it. It's much easier to replace a microSD card than  
to replace the NAND. :) Besides, you can get more storage for the OS this  
way.
