1) There's no lag between VoltDB confirming to clients that a write has been committed and that write being on disk. Zero. 2) The way VoltDB does persistence is actually quite different than MemSQL. VoltDB is able to write deterministic logical ops before the work even starts, while Mem has to write binary logs after the work is finished. The difference in practical terms is dramatic and will show up in almost any benchmark.
