Do the speeds of a PCIe 5.0 (or now 6.0) meaningfully affect anything for your average consumer? Would games load faster or files transfer faster? Or is this just at super high-end applications and hardware that you'd actually see a difference? I don't know if there's some other part of the hardware that would limit actual gains seen by the 5.0 and 6.0 specs.
...AI race consuming NAND flash at an extraordinary rate, but consumer platforms have not yet adopted PCIe 6.0 (and won't until 2030), making a consumer variant completely useless.
