Interesting, I thought it would. Just like a written hard drives weights more, than an empty one:

- Someone 6y agoI don’t think that calculation is entirely correct. Hard disks use error-correction schemes and codes to prevent long sequences of identical bits, so writing logical zero bits doesn’t imply writing “magnetic zeroes” (https://en.wikipedia.org/wiki/Group_coded_recording https://en.wikipedia.org/wiki/Group_coded_recording, https://en.wikipedia.org/wiki/Modified_frequency_modulation https://en.wikipedia.org/wiki/Modified_frequency_modulation). DRAM = tiny capacitors, so keeping more of them discharged would mean needing less leakage and thus less energy to top them up, though, so some gains could be made there.
