I do that..not just 750 MB sometimes 8 GB (in case of SAR images) ! So, I goto Copernicus data hub of ESA portal and select an area of interest and see the latest images. For eg,lets say for the Ladhak region, i download the latest images (in the case below it is from 30th Nov) shown here
and download the MSI image and preprocess the image to remove cloud and get to 10m resolution which is the spatial resolution for Sentinel-2A.
Now, if you compare the processed image and if you are lucky you can see structures. Like in the 30th Nov image you can see structures near 34.159780, 78.176042
which you wont find in the google map image
