How Much GPS Data Can the Columbus P-10 Pro Store on a 4GB microSD Card?
Quote from GPSWebShop Official on October 14, 2026, 12:11 pmA 4GB microSD card provides more than enough storage for most long-term GPS logging applications.
The actual storage capacity depends on the recording format:
Data Format Approximate Track Points Recording Duration at 1 Hz CSV 68 million 787 days GPX 37 million 428 days NMEA 25 million 289 days Calculations are based on continuous recording at 1 Hz (one track point per second).
At a logging interval of one point every 2 minutes, a 4GB microSD card can theoretically store over 50 years of GPS data, depending on the recording format.
