Most, if not all, of the studies we deploy mCerebrum for, have data rates that exceed 350Hz of continuous data collection from a variety of devices. These field deployments typically range from 14-30 days and result in a minimum of 423 million data points up to a maximum 907 million points per individual.
The paper only breaks down the aggregate sampling rate by device due to space constraints. Since this has not been published yet, I do not want to discuss it in much detail here at this time. The paper presents an analysis of total data rate capabilities and you can work out the effects of how the data representation affects effective sampling rate on a per sensor basis.
