This “Nifty MiniDrive” is a nifty way to add storage space to your MacBook. It’s a plug and play device that works in the best way possible – by being invisible. That doesn’t mean it’s transparent or pulls a Houdini on you. It just means it is light as a feather and you can snuck the minidrive into the SD slot, leaving no trace or evidence that you just got 2 GB of extra storage space. You can use the minidrive as part of a backup system, so that all your files and data get automatically backed up to it once a day when you plug it in. The Nifty Minidrive also happens to be virtually indestructible, since it is waterproof and shockproof.
