I am just looking for verification that I should toss out this disk and get a new one.

 

I am toying around with unraid on the trial period, so I scraped together every random USB drive I have lying around stuck them in an array and also took this 1TB SSD I have lying around and set it as the parity drive. I have been using resilio-sync to clone some data to this setup, which has gone well.  The only hang up is unraid keeps complaining about the 1TB SSD. I recycled this disk from an ubuntu machine.  So anyways none of that matters too much. What matters is I am new to unraid, and don't know if I am overlooking something simple, or is the drive really failing.  I know SSDs will loose their write endurance, and I am just going to have to accept less and less space on this disk?  I am fine with that, but label it as not reliable on only good for testing. Seems like I should use it as a read cache in that case. 

 

Here's the diagnostics file that seems to be the first troubleshooting step. 

 

Now that I think about it, I do have the SSD plugged into a janky usb-to-sata adapter. It's definitely worth it to take that out of the equation. So now I guess my next step is to test the disk again once I do that. I'll run an extended smart self-test.  Any other thoughts?

Disconnects such as you are experiencing is one of many reasons USB not recommended for array or pools.

 

Also, SSDs in the parity array cannot be trimmed.
