We lack precise data for production - we haven't really optimised yet and complete functionality isn't yet ready (it will soon, though). Rarely, we get around 8-9GB checkpoints (when bootstrapping for example), but they do not happen regularly. Normally, checkpoints are incremental and each 30 seconds they drop data of sub-1MB volume. We may change those values, but we'll still use incremental checkpoints. It's hard to tell when it comes to concurrency. It should be something around 20-30 threads writing small amounts of data, but due to the nature of the process, it's hard to know how many of this will be doing that at the same time.
