You can add up to 128GB of additional storage to your MacBook without having to have a new disk installed. With the Nifty MiniDrive, you can add storage to most recent models of the MacBook with an SD card slot. The MiniDrive is essentially an SD card adapter for microSD cards, but it’s designed to fit flush with the side of the MacBook. Since the card doesn’t stick out the side of the laptop, you can leave the card in place all the time, without worrying about accidentally hitting the card or finding that the laptop doesn’t fit into its protective sleeve with it in place. The MiniDrive is made of “precision-machined and hand-polished aluminum”, and it’s available in silver to blend in with the MacBook or in red. It fits so snugly, you’ll need to use the included removal tool if you want to take it out to swap microSD cards. It’s plug-and-play, so you won’t need any software to use it. Treat it as a secondary disk for storage or as an always-available backup disk. It’s available in different versions to fit MacBooks with or without Retina displays and to fit the 13″ MacBook Air. (There’s no model for the 11″ Air, because that laptop has no SD card reader.) The Nifty MiniDrives come with a 2GB microSD card, and you can replace it with up to 128GB microSD cards. Each MiniDrive is $39.99. They are available at Nifty’s website or Facebook page.
