Historically internal storage space within cycling computers was at a premium due to the price of memory and therefore to allow multiple / long rides to be stored without running out of space the manufacturers came up with the idea of SMART recording. The idea is very straightforward in that the bike computer looks at the current data from the ride (power, heart rate etc.) and decides if this data is ‘similar’ to the previous data that was recorded, if it is then the computer decides to discard rather than store the current data points and wait for another update from the sensors. This process repeats until the computer decides that enough has changed to make it worthwhile storing the data into the computers memory. While this does allow huge amounts of data to be stored it does produce massive anomalies in rider data which show up during post ride analysis.

The default setting in even brand new Garmin head units is to try and preserve as much of the internal storage space as possible and as a result SMART storage is enabled, we recommend that all athletes change this to 1s in order to create a detailed view of the ride and its associated data. Do not worry about running out of space, something like a Garmin Edge 1000 has enough space for hundreds of hours of rides and when you are close to running out of internal storage a warning is displayed.
