If you’re running out of storage space on your MacBook or MacBook Pro, haven’t used your SuperDrive in years, and don’t mind doing a little bit of surgery, you’re exactly the person OWC has in mind with its Data Doubler. This DIY mounting kit comes with a 1TB drive, so you can upgrade your Mac to internal storage of up to 1.75TB, or a full 2TB if you also swap out the drive that came with your Mac. Data Doubler fits in unibody MacBooks—white and aluminum—as well as all unibody MacBook Pros.
It’s important to understand that Data Doubler completely replaces your SuperDrive—but the MacBook Air has demonstrated that losing a DVD drive is not a huge deal these days. All of the tools for the upgrade are included, which means you can just follow the videos OWC has on its site and you’ll be good to go. Once installed, you can treat the drive however you’d like: as an individual volume, one large one in conjunction with the existing drive, RAID-0, Time Machine, or even as a pure Windows drive. (Wait, did we just say that?) In any case, it’s a darn good deal for less than $200, assuming you want to carry a mountain of data everywhere you go.
