As we've seen with the MacBook Air, Apple clearly feels there are a select group of you out there who can live without an optical drive on your laptop. Now, MCE is giving you unibody MacBook and MacBook Pro owners a similar option. The OptiBay is essentially a second hard drive that is installed internally in place of the optical disc drive, giving MB and MBP users the ability to vastly increase their storage space or tap into a RAID setup. The company has announced that said solution is shipping today to those interested, with options including 250GB, 320GB and 500GB drives. Oh, and if you're worried about that optical drive you'll be removing, fret not -- these guys have a nifty external enclosure designed specifically to give it another home. How quaint.
