The MiniDrive | microSD Adaptor | For MacBook Pro
The MiniDrive is a unique "short" microSD adapter that allows anyone to quickly and easily increase the available storage space in a MacBook Pro through use of the computer's standard SD card reader. With this adapter, you can take an inexpensive 64GB microSD card and add "plug-in-and-forget" storage space to your MacBook. A 64gb microSD card costs between $40 and $65 on Amazon.com.  When the MiniDrive is placed into the computer it is discretely hidden. The MiniDrive can be removed by inserting wire into a hole on the face plate and pulling.
