You can't rely on such latency. For example,
distance from NY to London is 5570 km (3460 miles). Nothing can move faster than light, so information can't be transmitted from NY to London faster than 5570/300,000 = 18 ms. Double this for standard TCP/IP. Double this for LA -> Moscow. Get 72 ms. Quietly weep

Please read it again, that is a more than optimal case for a hard disk, purely for illustration.
It is meant to show that using spinning disk drives for confirmations increases the lag expontially.
