I have been noticing performance issues recently, and in an attempt to diagnose the issue I ran a smartctl. I'll paste the full output below here but a few things stuck out at me, I'm just wanting to ensure I'm reading this report correctly. By what I'm seeing it appears my drive is past the threshold on raw read error's and spin up time. It also appears to have spiked at an extremely high temperature at some point (likely leading to the errors). These stats seem to indicate the drive is in "pre fail" condition and is likely to die at any moment. If someone would be willing to just look it over and confirm my suspicions, or call me an idiot and school me on how to properly read the report that would be great
