Disk cache overload and bad ssd

I have a couple of SSD (internal) drives, and my projects are all on one of the drives. I have a project with a lot of audio tracks and it maxes our the disc cache (like 100% instantly right when I hit play).

I backed up the project to the other SSD and it runs just fine (disc cache about 1-5%). (side note: I also tried backing up the project on the problematic drive in a different location, but it didn’t help).

Does this prove I need to replace the first SSD, or could there be another reason for the problem on that first drive?

Looks like the problem might be related to importing audio files, so I moved my comments to another post.
