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.
- mort96 3y agoOr write slower I guess?
- liftm 3y agoAt 75 MB/s, this thing takes 30 days to fill. How much slower would you like?
- gpm 3y agoWho says we need to fill it up in a reasonable time frame? If each disk costs a comparable amount to a dvd (cents) then the expensive part is the electricity (and maybe the equipment to write to them) and it's ok if most of the theoretical storage capacity goes unused. The important metric here for something like data backup is cost/byte to write and cost/byte/month to maintain.
- liftm 3y ago> Who says we need to fill it up in a reasonable time frame? 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.
- gpm 3y agoNo, I'm suggesting that it could take a decade and still given the numbers in the thread I replied to (which I agree appear not to reflect reality) be a viable product. It never needs to be 'full'.
- mort96 3y agoA few years maybe? The point of large storage mediums is rarely to fill them up as quickly as possible; rather the opposite.
