> According to the study, SSD's excessive carbon footprint compared to HDDs comes from the manufacturing process itself. The latest SSDs use multiple NAND, DRAM, and controller chips, each manufactured with cutting-edge silicon manufacturing techniques and multi-layer bonding processes, requiring both expensive materials and high electricity usage.

So it just comes down to… “too few nanometers”? If we manufacture the (non-memory) chips on older processes we’d cut this footprint? And was this compared to the HDD equivalent, i.e.: newer high-density Helium HDDs and such?

I thought it would be about the ecological impact of HDDs and SSDs when it comes to disposing of them, recycling cost and the amount left dumped in a landfill. On that note, SSDs are probably clear winners now that NVMe-s took over in consumer PCs compared to much bigger & heavier 3.5”/2.5” HDDs.
