Hi, I'm looking for a small, sleek external HDD that has USB3 and around 500gig of storage. I like the LaCie Porsche Design Slim Drive, but I dislike the writing on the exclosure. I really like the look of the OWC Envoy Pro, but that's only SSD and kinda expensive. And as far as I can tell, they only work with original Apple flash ssd. So, any suggestions? Thx!
