30ms latency is basically the best-case scenario you can expect for consumer internet (with a nearby datacenter and all that.) 10ms latency is about the worst-case latency for a rotational disk. And almost no consumer internet outside of Japan or South Korea is going to get more than 2 MB/s of real bandwidth, compared to 100 MB/s of real bandwidth from rotational hard drives.
Throw wireless or uploading into the mix (who's going to use a Chromebook over ethernet?) and it's even worse.
