You know, I tested this out last night by scrapping one of my spare light frigates.If you think your storage container on your ship is too large then why not make it smaller? You can't just look at starter ships and miners when thinking about cargo and volume, what happens when you start stock piling advanced armor for building warships? It may take you a week to fill your small salvager but a single cargo space only holds 100 advanced armor.
It added ten crates to my station's cargo hold (the image Master Artificer shared of the wee space all in grey). Either you're building a vast number of absurdly, lag-producing gigantic ships, or your server has tweaked settings.
