I have a WD My Passport and a My Book both of which have USB 2.0 cables. I just got a new rMBP, so I'm looking for ways to remove bottlenecks. The My Passport has a Micro USB port (the little one that cell phones use, not the wide one that newer WD drives use), and the My Book has a Mini USB port. I'm more concerned about the My Book since that's the one with my Time Machine backups. The My Passport just has video files on it. I know the USB 3.0 cables are probably out there, but I'm also interested in TB 2 since otherwise I will probably never use those ports. Thanks! Also, has anyone seen a Thunderbolt to Lightening cable?
