I'm confused about what storage my Macbook has
I assumed HDD because the 'secure empty trash' is available. When I go into Disk Utility there are 3 disks / volumes (Mac HD, 320gb internal SATA & Media).
There is the option to perform Erase Free Space on 1 and 3, which tells me that these are HDD, but what is the middle SATA one (and are files stored there)? Is the middle one SSD? Or if it is an HDD, why can't I perform an 'Erase Free Space' on it?
