You don't have to worry about where a file is stored, or remember which drive to you created a folder on - it's all the same. So if your MacBook has 128GB of onboard SSD storage and you add the 256 GB TarDisk, OS X will combine the two into one 384GB hard drive. Meaning, your Mac will treat TarDisk as additional onboard storage.

The other option - and the reason you pay so much for TarDisk - is to "Pear" the card with your Mac's internal drive. OS X views TarDisk as any other external storage volume, where you can store files or even use it as a Time Machine Backup destination. When you first slide a TarDisk into the SD reader on a MacBook, it's treated just like any other SD card. It's one of the more expensive storage solutions you'll find when searching, but you're also paying for the Pear software that comes with TarDisk. TarDisk is available for the MacBook Air, MacBook Pro with Retina display, and older MacBook Pros. Once the setup is complete, TarDisk acts just like onboard storage.
