That's not what consistency means in ACID.

I'm pretty sure there's no durability there. That statement is pretty disingenuous in itself, but it'd be nice to see a number for durability (which, granted, is not something you advertise the product for).
My main concern is that all these speed benefits are going to be eclipsed by the 0.5ms of network latency.
