So, has anyone noticed any issues when completely filling up a Vertex 3? Mine is about 25% full and I want to throw my Itunes library on it, leaving it at about 70% full. I've heard in the past that keeping the drive at least 50% full is crucial to it's performance, but that it may not be the case with newer drives. Anyone have any first hand experience? I don't mind playing my music off my network/external drive if it will hinder performance on my drive AT ALL, but if I can be assured it won't - then I'll just do it. Thoughts?
