Nifty MiniDrive 4GB Expandable Storage for MacBook Air 13-Inch, Red (MD3-RP-AIRRD4G)

Adding storage space to a MacBook shouldn't be complicated, but it can be. The MiniDrive is our solution. It's simple to use, non-destructive and lets you add up to 128GB of extra space. It also weighs next-to-nothing, fits snugly into your MacBook's SD card slot and is pretty much invisible once plugged in. The way we see it, a product built for a MacBook should be engineered to the highest standards. Every MiniDrive is capped with precision-machined & hand-polished aluminium before being carefully assembled, tested and shipped. We designed the MiniDrive to be as close to seamless as possible once it's plugged in. Through countless hours of tinkering we've tailored the color, shape and fit to match your MacBook perfectly. You'll barely know it's there. The MiniDrive integrates with your MacBook's native Time Machine. Setting up a daily back-up of your critical files takes seconds, and will run automatically while your MiniDrive is present. The MiniDrive is water- and shock-proof, unlike your MacBook. If the worst happens you'll still have all of your important files to hand.
