Please forgive me for my ignorance, but are there currently any ways of being able to write data down at that speed? I see 2026 PCIe 5.0 NVMe advertising theoretical 14gb/s but not sure how feasible even that is.

PCIe 5 drives max out at about 14 GBps (bytes), which is ~112 gbps (bits).
Displayport 2.1 UHBR20 is 80 gbps.
USB4 maxes out at 80 gbps.
As you can see, 1gbps ethernet is starting to look like stone age technology. 2.5gbps becoming the next step seems a bit strange when we were jumping orders of magnitude every few years before. But also, ethernet tends to be used on longer cables than DP or USB, and trying to push it much faster results in exponentially increasing losses to resistance and radiation, the cable starts acting like an antenna even with the twisted pairs. Fiber optics are much better suited to high speed long distance, but too expensive and fragile for consumer use.
25 gigabit/s is 3125 megabyte/s, the SSD in my 4 year old laptop can write at nearly 6000 megabyte/s.
