Which begs the question. Why do you need the whole of the earth? Are you really going to explore the Amazon, the Himalayas, the Sahara desert, both Poles and all of the Pacific Islands?
Unless you are collector of everything, all you need are the tiles that cover the area in which you are thinking of flying over.
If you download the lot all you will do is add to the profits of hard disk manufacturers.
Terrsasync will provide areas that you fly into and don´t have locally - and the data will be more recent than a tile that you downloaded a few months previously.
It is however a good idea to manually download tiles is when you want to start at flight at an airfield that is outside your current downloaded area. Terrasync can cope with this, but a manual download before the flight is often simpler.
