Without opening the case, is there any way to tell if I have an SSD installed in my laptop or if it's a spinning disk?

Right but how do I check the disk model? I bought this laptop used so the previous owner may have switched it out.

Code:
cat /sys/block/sda/queue/rotational

"1" means not an SSD.

I got "0" but I can hear something working inside the laptop when the room is quiet. It's not the fan, it's clearly synced to what I'm working on. What is that?

Could be electrical noise leaking into the sound circuits, my laptop's that way too.
