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

    I suggest that you open a terminal window and use the command line tool lsblk for example with the following options: lsblk -o name,size,fstype,label,mountpoint,model; You may want to make the terminal window wide so that all output for each device will fit into one line. – sudodus Aug 19 '21 at 14:08

    You want to install to the NVMe device not sda. The NVMe device is the SSD. You can change some settings & change some defaults to make system boot faster. See: https://askubuntu.com/questions/1284302/is-it-possible-to-make-ubuntu-20-04-boot-faster – oldfred Aug 19 '21 at 14:38

    sda is the HDD; nvme is the SSD. Any modern OS installed in a HDD will be slow. – ChanganAuto Aug 19 '21 at 14:38

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.
