Price is only one concern of many.  With an embedded storage appliance
TDP and low power draw are as important as price.  For instance, a 64bit
dual core, 4 thread 1.86GHz Intel Atom N2800 has a TDP of 6.5 watts.
Each core is easily capable of handling IO and parity for 8 rust drives
making it an excellent fit for this storage appliance.  There are dual
core MIPS64 chips that are suitable as well.
