Strengths:
- Adds 64 GB of internal memory for a reasonable cost.
- Is quite fast read (60MB / s with me) for an iTunes or iPhoto library.
- Not the side of the MB looks good, it is just over, just a slight bump on the side.
- Does not fall by accident, the card is securely maintained, and even a little difficult to remove.
Weak points:
- A bit slow in writing (10MB / s).
- Black plastic look.
- Requires the installation of Toolbox software JetDrive, otherwise the card prevents the Macbook to go in deep sleep.
