This is my attempt at a belt storage for space platforms.

Storage capacity: 81354 items
Area: 52x52 tiles
Density: 30 items per tile (=3.76 straight belts per tile)
Time to empty the belt: 40-45 minutes
Blueprint: https://factorioprints.com/view/-OBZyyrP5snX9bGUOBPT

Fill and empty speed should be the same as it's just one long belt and it seems to be capped at 30 items per second. Is that correct?

And shouldn't you fill the little 2x2 squares with some more undergrounds?

The fill and empty speed depend on the distance to the first red belt from the start and from the end. Since these two distances are different, the times are different.
If I find a way to fill these 2x2 squares with additional belt storage, I will. Currently they are already packed with 5 or 6 overlapping belts, so it's not as easy.
