How long should fsck take to scan a drive?

I woke up one morning to find my Ubuntu 20 laptop unresponsive, so I rebooted, and arrived in a BusyBox "(initramfs)" prompt.

Typing "exit" told me that:

The root filesystem on /dev/sda2 requires a manual fsck

So I ran fsck /dev/sda2 -y.

That was a day ago. It's still printing out a ton of messages like:

Inode <number> ref count is 2, should be 1. Fix? yes
Unattached inode <number>
Connect to /lost+found? yes

My drive is 160 GB. How long should this take?

Is it stuck in an infinite loop or does this really take more than a day to scan a drive this size?

This is a solid state drive which I've previously never had any problems with. I know those to sometimes fail. Is this a sign that the drive is probably toast, or should fsck be able to recover it?
