37.8 kWh per TB, so about 10 kW at a write speed of ~75 MB/s (~3.7 hours for the TB).
That means you'd not only have to deal with the heat dissipation of ~five space heaters at full power, but you'd also need three-phase power to supply it.

So you yourself are saying anything longer than a month is unreasonable?
In any case, this lab experiment will need much improvement in speed and energy requirements.
