The source on Embodied Carbon in SSDs seems to be this 2022 paper: https://hotcarbon.org/assets/2022/pdf/hotcarbon22-tannu.pdf https://hotcarbon.org/assets/2022/pdf/hotcarbon22-tannu.pdf ; but unless I'm mistaken, it does not claim anything like the full Seagate "report": https://www.seagate.com/content/dam/seagate/assets/resources/decarbonizing-data-report/pdf/decarbonizing-data-report-03-2025-a4-en-gb.pdf https://www.seagate.com/content/dam/seagate/assets/resources... ; there might have been an "extrapolation" because 30TB SSDs did not exist then (outside labs).
I'd treat it with a two-order of magnitudes (at least) grain of salt.
- Timshel 1y agoThx, there is a graph for embodied cost at the start of page 3 and figure vary wildly. The biggest drive at the time was 3840GB, and its production emitted ~425kg. But if we look at the more prevalent models the emission vary widly: for 512: between ~25 to 225kg and for 1024 from ~60 to 275kg. And while the paper start with the assertion that manufacturing a Gigabyte of Flash emits 0.16 Kg CO2, I expect emission to be highly dependent on the number of flash module and not so much on the capacity itself.
