MacBook GuideBook features HyperDrive for MacBook

HyperDrive is the most convenient way of adding more drive space to your MacBook Pro or MacBook Air. Instead of plugging in a portable drive, just slot a Micro SD card (sold separately) of up to 128GB into the HyperDrive, and then slot the HyperDrive into the notebook’s SD card reader. Make sure you get the correct HyperDrive for your particular model of MacBook. Excellent price too. www.hyperdrive.com
