If you read the guide carefully, you would see that it is both. The SSD is used just for the OS, but since it doesnt have enough storage for what is wanted to be accomplished he used another HDD, non SSD, to store certain folders and applications on there. So it is a combination of both SSD and mechanical HDD to accomplish this goal.
