Abstract: Systems and techniques for storing and analyzing data. For instance, computing device(s) may store sensor data in first data files included within a first data buffer of a first memory, which may include a cache memory. The computing device(s) may then store metadata in metadata files included in a first metadata buffer of the first memory, where the first metadata files correspond to the first data files. After storing the data, the computing device(s) may determine that the sensor data represents an event. As such, the computing device(s) may store the sensor data in second data files included in a second data buffer of a second memory, which may include an archive memory. Additionally, the computing device(s) may store metadata in second metadata files included in a second metadata buffer of the second memory, where the second metadata files correspond to the second data files.
