We like the simplicity of logo #19. Not sure what the multi-color bubbles mean - but we don't like those. Can we see the a "top view" version of a brain image integrated into this logo somehow. Such as by replacing the "O" in "Storage" with a top view image of a brain. Or place a brain element to the left of "Storage." We like the simple font as well. The use of grey scale colors is ok - "grey matter" is a subtle way to connect with brain. We like the integration of the tagline too.
