How much space does Google Earth take up on your computer?

google Earth only stores as "small" amount of data cached on the client computer typically 50-100 MB for the base imagery and up to 2GB for the local disk cache depending on the platform.

From reports in 2006, the google Earth data servers have 70.5 TB for both its map imagery and index data, and Personalized Search uses 4 TB. With the high-resolution Street View imagery added every month, the amount of data will be larger now.

A report in 2016 estimates the total size of the google Earth database is 3,017 TB or approximately 3 Petabytes not including Street view imagery.
