2. CoinTerra TerraMiner IV

CoinTerra’s TerraMiner IV is a water-cooled Bitcoin mining machine powered by CoinTerra’s own in-house ASIC chips, the GoldStrike I. The TerraMiner IV is built on a 28nm process and comes in a 4U enclosure with a power supply included, which is a rarity in Bitcoin mining circles.

The TerraMiner IV has four ASIC chips, and with each boasting a 500 GH/s hash rate, it means that the TerraMiner IV has a total hash rate of 2TH/s. At the current mining difficulty, that translates to just over 1.1 Bitcoins a day. CoinTerra also claim that the TerraMiner IV is power efficient, although there are no numbers available yet to prove this claim.
The April batch for the TerraMiner IV is open for pre-orders.
