- Don’t Erase Data

Don’t Erase Data is quick and provides the least security. It deletes just the information used to access your Mac OS X files and leaves the data in the file unchanged. Available Disk Recovery applications can restore the data after this operation.
Zero Out Data is fast and gives good security. This is best one option and mostly users choose it. It deletes the information used to access your Mac OS X files and writes only zeros over the data.
