I am having issues with my cache drive, the drive just seems to stop working or slowing down so much its unusable. I did a manual test where i just wrote a large file to the cache drive and it goes steady until it reaches a couple of gigs transferred and then it just drops to 0. Transferring directly to the array has no issues what so ever.
So i wonder if i have a broken drive or if there is something in my setup that is wrong/broken/messed up?
I added 2 diagnostics, one is after the drive goes haywire the other is after a fresh boot.

Device is dropping offline, this is not usually a device problem, but it can be, did it start doing this out of the blue without any hardware or software changes?

When it happened the first time i just started some downloads and i was updating some docker containers. But docker become unresponsive.
I did test with everything docker disabled and i can cause it to happen just by transferring large files to the cache.

Sounds like a device problem, especially if it's a recent issue.

Got a new drive and restored everything that was on it. Everyone is back to normal so it does look like it was a purely hardware issue. Thanks for the second opinion!
