TerraHash is a bitcoin mining company that sells boards and kits for Avalon ASIC chips. They launched their website in April after Avalon announced they would be selling 282 MH/s ASIC chips in lots of 10,000 . Bitcoin ASIC chips are the customized components in bitcoin mining that perform the mining calculations. TerraHash offer a wide range of products, with various customization options. There offer two types of products, individual boards that run at 4.5 GH/s or 18 GH/s, as well as complete kits that run either the small or large boards.
This board is based on the Klondike 16 opne-source design, and contains 16 Avalon ASIC chips. This board can be used with either a computer, or a Raspberry Pi board, and multiple boards can be connected through the same device. From their site, features inclue:
If you provide your own chips, assembly on the board will cost $90. Using TerraHash’s chips on the board will cost $250. It’s important to note that this only includes the board, and no power supplies, cables, or housing unit. For these an assembled kit will be available.
The 18 GH/s board is almost identical to the 4.5 GH/s board, however it uses 64 Avalon ASIC chips instead of 16. Additionally, the board will have a larger form factor to accommodate the increased number of chips:
Pricing for the 18 GH/s boards starts at $250 for assembly of customer-provided ASIC chips. Using TerraHash’s chips will cost $900.
The DX Mini is a complete kit option for the 4.5 GH/s boards. The body unit can hold up to 20 modules, totaling 90 GH/s. The case itself costs $1000, and prices vary by number of modules up to $6,000 for the 90 GH/s unit. Each module runs at 32 Watts, and the entire unit comes complete with a case, installed boards, heat sinks, power supply and cooling fans. Additionally, it comes with software for Windows, Mac, and Linux that uses cgminer.
This is their largest unit, and customizable with up to 10 individual 18 GH/s modules, totaling 180 GH/s. The 1 module unit sells for $2,500, while the 10 module unit sells for $10,500. Each module runs at 128 Watts (compared to the 32 Watts of the DX Mini) and like the DX Mini the entire unit comes complete with a case, installed boards, heat sinks, power supply and cooling fans and software.
On June 14th, they announced on their blog that pre-orders will begin on Tuesday June 18th at 9am Pacific Standard Time. Additionally, those who already registered accounts on their web site will have a 24 hour grace period to order before it is opened to everyone. Payment methods include BTC, PayPal, or Wire transfers. After placing pre-orders, customers can expect to receive their products in mid july
Shipping dates depend upon when we receive the chips from Avalon. Once we have the chips, we will start shipping the orders within 2 weeks. We hope to get the chips between mid and late July. If you are looking for assembly, its the same estimate. Once we receive your chips, we will be able to start shipping out your boards in 2 weeks.
They have have a working prototype of the Klondike 16 working from Avalon’s test chips, so it looks like they will have some opportunity to get the drivers prepared before the full batch of chips arrive in a few weeks. Though there is clear vulnerability in their product schedule if Avalon does not deliver on time.
At current difficulty, the 180 GH/s unit will return 4.6 BTC per day, with an expected break-even including electricity costs of 22 days. While the future difficulty in July is anyone’s guess, even if network difficulty tripled, a break-even of ~66 days is not unreasonable.
Unproven mining hardware providers should be considered carefully alongside the risks involved with any such purchase or pre-order.
