MacBooks are not cheap laptops. The price goes up dramatically when you add more RAM or hard drive storage. Upgrading MacBooks is not for everyone. The MiniDrive is a cool solution that lets you add more storage to your MacBook. You can add up to 64 GB of external storage to your machine with this. This lightweight mini drive fits in your laptop’s SD card slot and stays almost invisible. Not cheap but beats having to do a manual hard drive upgrade.
