The basic models of the MacBook Air and the MacBook Pro come with a measely 128GB of storage, which is unsurprisingly easy to fill up (considering Apple installs so much “stuff” on the Mac before you even get it).
The TarDisk looks like a small sim card/ USD drive/ SD card. TarDisk designed to merge with your existing drive, giving you a much bigger hard drive with a single volume for storage, it has also been designed to seamlessly merge with your MacBook’s exterior. The flash storage card is sealed in your Mac’s aluminum tray which slides flush into your SDXC port. It’s designed to permanently pair with your existing storage to form a single volume.
