ELI5: How do Solid State Hybrid Drives work?

I don't understand how a regular hard drive can work with a solid state drive at the same time.

Imagine the sshd (solid state hybrid drive) is a refrigerator.

A few times a day, you come back to the fridge to get a glass of juice. You take the juice out. Pour some in a glass and put the juice back. Presumably near the front of the shelf. Because its at the front of the shelf, you can access it very quickly. But there is not much space on the front shelf, so you only put a few things there.

 Now, its time to make some dinner. You need pickles, which you only use maybe once a week. So they are in the back of the fridge, where there is a lot more space, but its harder to reach them. So it takes a little longer for you to get at them. But you eventually succeed, and put them right back where you found them to be used next week.

Now, to explain how an sshd works, replace the food items above with computer files, front shelf with ssd, and back shelf with hdd.
