Well, guaranteed consistency requires coordination and if your coordination mechanism is over a network, then the speed of your writes will be multiple factors of your network latency.
"network" doesn't necessarily have to mean high latency ethernet though. You can have a network running on top of an embedded backplane in a blade system. There are ways to minimize latency, but latency is as latency does.
