Gigabit is what most homes start with, and for the vast majority of home networks, that’s more than enough. But then, you buy a new PC that has 2.5GbE capability, so you upgrade the switch and router to match. Then you get more devices that can handle multi-gig, and it turns into a constant temptation to level up to the illustrious 10GbE. 10-gig isn’t for everyone, but if you want to upgrade a few of the load-bearing devices in your home, 10GbE cards are constantly being pulled from decommissioned enterprise servers and can be bought for a fraction of their original cost, and it’s one of the best ways to upgrade your speeds.
