Seriously, if I were to start a pool I would find anything below 250 or so giga bad to start - and vladimir may be able to add 50gb for the mere price of 5gb of my capacity. I will never understand why people mine in a pool that does not solve a block on avereage every 6 hours. The variance will jsut totally kill you. Whoever mines in one of those micro pools - wants thrill, not money.
