€200 buys you a 1tb ssd even at todays elevated prices. That has no problem giving you 10gbit of sequential io.

Four or five 7200rpm disks in an array can also sustain it for sequential reads of big files. That costs less than a gaming laptop.

A potato can saturate a 10gbit line if the data is mostly in memory.

For lots of small files in random sequence and cold caches it gets a lot harder.
