System has suddenly become VERY slow. I provide some command outputs, is my disk failing?

Hi, my system has all of a sudden become very slow. I don’t remember doing anything in particular, after the laptop was suspended and I resumed it, it was suddenly very slow. This is a laptop with only Manjaro Linux KDE (Stable) installed on the drive.

Opening webpages, opening files or folders, everything is VERY slow; even when typing this message, the characters show up after a small delay. Restarting didn’t help. I don’t think there is any particular process taking up CPU, so I think it’s the disk. Please see some outputs below:

What’s funny is that I don’t remember my Linux particitions having those paths, they used to be “sdaX”

I downloaded DiskMonitor to check my disk but when I open it is says this:

Any help would be hugely appreciated, thank you in advance.

Looks like both of your S.M.A.R.T tests passed.

Can you post your fstab mounting options?
you can get it with cat /etc/fstab

after that can you try logging into tty? so logout of normal user and once back at the login screen use Ctrl+Alt+F2
It should ask you to login to a termanl, you can then test the speed of your key strokes etc.

Hi @akin2silver , thank you so much for replying.

Interestingly, the problem solved itself. Not sure why, I just moved the laptop to another room and poof it was working perfectly again. I am providing the command output below, but I will wait for it to become laggy again (hopefully never) to test the key stroke speed in TTY. Thank you very much for replying though.

cat /etc/fstab

To being clarity, the s is the port the disk is connected to: _S_ATA.
Your disk is connected with nvme.
