The Pi is an armv5 and limited in a number of ways. The RPi2 is a duo
core armv7 that does better, but is still short of memory and I believe
only has USB for a HD attachment.
The Cubieboard2 and Cubietruck are both Allwinner A20 duo core armv7.
The C2 has 1GB and the CT 2 GB memory. C2 has a 100Mb and CT a gig
ethernet. Both have a sata interface. Both can easily handle a 2.5"
HD, the CT can handle a 3.5" HD (with the addition of 12V). Go look at
the specs. And look for a source near you.
There is also the Wandboards and the BananaPi to look at. I have heard
problems with the OrangePi.
But an armv7 duo core beats a single core armv5 hands down. Add a HD
over an mSD and you have a real appliance server. Not a DIY hobby
machine (My personal observation).
Oh, and the quad cores are coming out. Both Wandboard and BananaPi have
them. Cubie has theirs in final build design.
Then you can go the the armv8 which are 64 bit and more of a data center
server platform and pull typically 18W instead of the 2-4W of the
armv7... Oh and COST a lot more!
