Why has no one thought of this before? MCE Technologies's MCE Complement is an all-in-one, portable USB 3.0 device comprised of a 2TB hard drive, a Blu-ray/DVD/CD Reader/Recorder, a USB 3.0 Hub, and SD card reader. It's a perfect Complement (pun intended) for recent Macs that come with no built-in optical drive and limited storage.
The MCE Complement's 2TB hard drive is designed for use as a standard storage device and is compatible with Mac OS X's Time Machine. It can be configured as your backup disc and set to back-up your Mac whenever you connect it (very handy, since it's portable). Or you can set it to back-up your Mac at regular intervals with Time Machine.
With its 2TB hard drive, the Complement can also serve as home to your photos, songs and movies. With most Macs topping out at 1TB of internal storage (500GB on laptops without expensive build-to-order options), you can use the MCE solution to store your multimedia data, leaving your Mac's hard drive with more space. The Complement's drive is also removable, so it's easy to replace should you ever need to do so.
The Complement comes with a lifetime license for Mac Blu-ray Player software, which lets you play commercial Blu-ray titles directly on the Mac. Since Apple is never going to support Blu-ray, this software/hardware combo is arguably the best way to watch Blu-ray movies on our Mac.
The MCE Complement can record data and high definition video to 25GB, 50GB, 100GB, and 128GB Blu-ray recordable discs. It's also a more-than-suitable replacement for Apple's SuperDrive as it reads and writes all CD and DVD formats.
The drive is compatible with Apple's DVD Player application for the playback of DVD movies as well as with Finder Burning for burning Blu-ray Discs, DVDs and CDs at the Finder level. Blu-ray authoring of high definition video can be accomplished through the use of Roxio Toast 14 Titanium with HD/BD Plugin (which can be purchased with the Complement for an extra 80 bucks), Final Cut Pro X, or Adobe Premier. The drive is bootable and is fully compatible with all DVD and CD recordable media.
If all this weren't enough, the US$249 Complement boasts an integrated USB 3.0 hub as well as an SD Card Reader. It connects via a cable to a single USB 3.0 port on your Mac through which all power and data communications are transmitted. Located at the side of the Complement are two USB 3.0 ports and one USB 2.0 data/charging port. Connecting devices to the Complement's USB ports is a lot more convenient than searching for ports behind your Mac.
However, the Complement also packs an extra power supply, primarily to provide additional power in the event you want to connect other power hungry USB devices to it such as bus-powered hard drives. Or perhaps you also have something charging from the white USB charging port. If you're doing all that then you probably have a power outlet nearby. For the vast majority of uses you won't need the extra power supply, but MCE opted to include it for completeness' sake, which I appreciate.
