Honestly no idea so this is merely speculation but;

I believe the Aeva Media is a plugin for the SMF board which allows better categorisation and management of uploaded pictures and integrates them in to the gallery.

Essentially, attached pictures are just attached to an individual post in a thread. The Aeva uploaded ones can also be found in the Media Gallery (see link at the top of the page)

Pretty sure there is no load / performance benefit
