I am pulling my hair out here, this cache drive has been the bane of my existence since the day I installed it. It throws constant error about overheating, and has even filled all the way up and locked itself into read-only a few times when unraid was reporting it just past halfway full. The last straw was last night when it failed 3 times, and I ended up sticking it in the fridge for a minute since it seemed warm, which is not normal. 

 

Samsung 870 EVO 1 tb - running in XFS after the second time it locked up after filling itself up. Purchased 4 months ago and was tested out of the box. Usually holds appdata and downloads shares only, downloads set to Prefer. When it fails the Cache drive seems to unmount itself and is solved fastest if I can pull the drive, reboot the server, plug the drive in after boot, and then restore appdata fro CA Appdata Backup and Restore.

 

I feel like there has been a pattern of failure when under load, or maybe heat? I can't seem to make heads or tails of it, and am guessing those are the symptoms of it rather than the cause. Thanks in advance for taking a look and helping me out.

Constant ATA errors, swap cables with a different device to rule that out, if issues follow the SSD replace it.

Thank you! I just replaced the cable and will try and put it under load to see if I can get it to fail!

After a few NZB's it dropped again, in case it helped I gathered another diagnostics file after it had failed. I will start looking for an SSD to replace it with but if you have a second to look through this second report let me know if there is anything else weird happening there.

Similar issues, assuming you were using different power and SATA cables replace the device.
