Confused if my OS is on SSD or HDD

My laptop has both HDD and SSD, I recently installed Ubuntu 20.04 and I felt the system is bit slower I checked it with the command "lsblk -d -o name,rota" and I found the sda value is 1 so I installed it again changing the installation path to (dev/sda) and again the rotation value still shows 1 and the system is slower than before. The only change I observed is in loop values. Can someone please check the attached image and let me know which one is of SSD?

Before and after changing the installation path

Solution 1:

Open a termial and type sudo apt-get install gparted
Then run gparted and it will show you what you want.
sudo gparted and then click on View/Device Information from the top menu. Don't mess around, linux doesn't ask you twice so if you delete or format something here you are going to mess it up.
