I don’t know if this is hardkernel, but if not, note also that MaidSafe and a few folk on the forum (including myself) are using Odroid devices for testing and farming Safecoin (see for example: Farming Hardware: Odroid U3 and How to build MaidSafe on Odroid-U3).
Regarding info on farming, basic information at: http://maidsafe.net/SystemDocs/user_perspective/farmers.html
There is no definitive information on farming rates, performance hardware etc. Just some posts where folk including myself have commented based on what we have learned from various places (much of my understanding has been gleaned from comments I’ve seen from David Irvine).
Essentially, my understanding is that farming effectiveness will be a product of rank and available storage, where rank will be influenced by the usefulness and trustworthiness of a node, which is calculated from a combination of factors. But the most important seem to me to be availability, and response time.
Availability is important because if you aren’t available, you won’t get rank or be around to receive data.
Response time will be important because every farming opportunity is competitive between the four nodes that store the requested chunk, and only the fastest node will get the reward.
I do also believe that it is in the network’s interests to encourage farming on a widespread basis, and since even relatively poor nodes will add value to the network, they will I expect be rewarded to some degree. I would not be in the interests of the network to function in a way that encouraged centralisation within a subset of the highest performing nodes, though higher performing nodes will be rewarded for their performance, I don’t believe they will be able to “corner the farming market”.
Please note that I may be wrong with my facts or analysis. But that’s what I understand. Anything way out, I hope @dirvine will correct!
