The Bitmain Antminer S21 Hydro (395 TH) — The strongest Bitcoin miner of all time

 

The Antminer S21 Hydro is Bitmain’s latest cutting-edge, water-cooled Bitcoin miner, setting a new standard in the industry. Boasting a remarkable hashing power of 395 terahashes per second (TH/s), this miner operates at just 5925 watts, making it one of the most powerful and efficient Bitcoin miners available.

A key feature of the Antminer S21 Hydro is its innovative water-cooling system, which significantly enhances heat dissipation and cooling efficiency. This not only ensures optimal performance but also extends the lifespan of the hardware by keeping temperatures in check. Additionally, the reduced energy consumption translates into lower operational costs, making the S21 Hydro a more eco-friendly option compared to traditional air-cooled miners.

The miner is designed with user convenience in mind, featuring a user-friendly interface that allows for easy monitoring and management of mining operations. With real-time data on hashrate, temperature, and energy consumption, users can stay fully informed and optimize their mining activities for maximum performance.

Overall, the Bitmain Antminer S21 Hydro offers a powerful combination of high performance, energy efficiency, and ease of use, making it an excellent choice for both individual miners and large-scale operations.

For those interested in scaling their mining setups, various cooling solutions are available. These include external cooling units for single miners, server racks accommodating up to four hydro miners, and larger-scale options like the Bitmain Antspace HK3 V6, which can house up to 210 hydro miners for more extensive mining projects.
