Dataset sizes
The table below lists the file sizes of the datasets on the public APIs server.
In most cases I converted the source files to compressed geotiffs, and the sizes given are after that conversion. A freshly downloaded dataset could be much larger depending on the format, but compressing with gdal should result in a size similar to what I ended up with.
