I couldn't find any information on persistence and crash recovery for this thing... is it able to beat Volt because it doesn't write to disk?

In fact we do write a redo log to disk (Set the REDO environment variable, e.g. REDO=$filename bin/driver when running the driver in our example download). VoltDB tries to be fast at highly partitionable workloads and does not provide OLAP-style query support. HyPer aims at bringing OLTP and OLAP together into one system.
