Yes, but I wanted to see ones showing the parity sync, which is going at 185MB/s, quite normal, also note that most of your disks are SMR, including parity, so some write performance degradation is expected.
Go to Settings -> Network Settings -> Interface rules and make the Gbit NIC eth0, then reboot, it will have the same settings as the older eth0.
eth1 should then use a different subnet for the direct PC connection.

Device is failing to initialize, if you can test with a different OS to confirm if the device is working or not.
Disk is OK for now, but like mentioned it doesn't look very good, it will likely fail again in the near future, up to you if you want to give it another shot or replace now.
That looks more like a power connection/problem, and the disk looks healthy, but if the cables were replace/swapped and the problem persists it might be a disk problem, like mentioned above you should run an extended SMART test since the ones started never finished, likely due to spin down.
Looks like a power/connection problem with the parity disk, check/replace cables and try again, look at the syslog to confirm the ATA errors are gone, or post new diags.
