The data coming from the sensor isn't particularly fast, it's about 7Hz and what I need to store is the time since the start of recording (in seconds, stored as a double) and the value from the sensor (also a double). I could easily see an hour of data being collected at one time which I (very) roughly estimate as being about 1.5 Mb of raw data. Ultimately this would need to be saved in a human readable format (or at least an Excel importable format) maybe tab delimited text, so the file size on disk would be several times bigger.
So any thoughts? Recommendations? Am I better off trying to store as much as possible in memory and then only write to disk when recording ends? Or is it better to try and write pieces as it's collected?
