M.2 10GbE network cards aren't novelty products, but they used to cost a bit of money. However, pricing has improved over the years, and now you can find them for sub-$100 price tags.
The 10 Gigabit Ethernet (10GbE) standard, which debuted in 2002, hasn't entirely caught on, but its adoption rate is improving. 10GbE networking provides up to 10X higher performance than your standard Gigabit port. We're looking at transfer speeds up to 1,250 MB/s. However, you'll need the infrastructure to take advantage of 10GbE.
