As a big Calibre fan I can't ignore this statement (much against my better judgement
).
The reason the cover/metadata is stored separately is that Calibre supports many book formats, not just epub. Some formats can't store images/metadata internally e.g. TXT. Other formats can store some metadata items but not others. The 2 external files just standardise everything.
Additionally, DRM epubs and PDFs may contain a cover you don't like and can't edit. The external cover image allows Calibre to automatically send the cover of your choice to be the thumbnail on your Sony.
Additionally the separate metadata file is is stored for your own protection. If your Calibre database (metadata.db) gets corrupted Calibre has a feature to be able to recreate it from your book files, and separate cover and metadata files.
Sorry to digress
