I think the background image takes up too much space and makes it too busy. The text in #4 and #5 puts the focus on HUB, rather than "Storage" which is frankly more important. You could try reversing it, but I'm not sure that the lighter color will work for the text. You might want to try some other variations instead. I don't love the triangle/electron type thing, but the box isn't a bad idea. You might be able to play off that idea in some interesting ways.
Got it. I've ditched the background image -- the "triangle/electron thing" was meant to be representative of "hubs" coming off of a central spoke -- a semi-literal illustration of the site's function. I like the concept of the storage box, and again, something that illustrates a "hub." Trying to stay away from anything that reads as "Security/safety," because A) that should go without saying and B) if I understand correctly, this is a site providing info on other companies' storage facilities, not your *own* storage facilities -- therefore it might be a bad idea to focus on traits that don't apply directly to the service that you yourselves are providing.
The rotating satellites just don't do it for me. The packing tape is an interesting idea, it just doesn't look like packing tape to me. I don't know if you can really make that one succeed, but I would like to be proven wrong. I actually thinks it's OK for us to instill security and safety since that is an important thing that people are looking for.
