I tried some numbers for writing to hard drives (it seems like SSDs are hard drives are not super far-apart on energy per byte written)
And it seems like writing to HDDs is between $.15 to $.56 per TB depending on write speed and watts/time assumptions. It gets tricky to think about because there the sunk cost of powering the drive when idle, and the delta between idle and write power needs, but I think that range is representative for $/TB on a HDD.

- tgsovlerkhgsel 3y ago> writing to HDDs is between $.15 to $.56 per TB That seems obviously wrong (writing a TB will consume less than 1 kWh), and indeed your link shows 0.56 cents (i.e. $0.0056) per TB.
- zoky 3y agoIt is definitely wrong, there’s no way a hard drive that can write a TB in, say, 4 hours would consume anything close to 250 watts.
