  1. That should not happen when adding a new device, something weird still going on there, try this:

     

    Unassign the second nvme device, also wipe it with wipefs -a, set pool slots to one, start array with just the 1st device, stop array, set pool slots back to 2, re-assign 2nd device, start array, if it doesn't work post new diags.

    and the fastest write speeds I see are 150MB/s, which seems awful slow.

    That's not that slow, Unraid doesn't stripe disks, so it's limited to the speed of the slowest disk at any point, you can post the diags so we can see the hardware used.

    rsync starts at 200-300 MB/s but then slows down to 3.7 MB/sec

    Is the parity sync/check done? If yes post the diags during a transfer, after it slows down.

     

  3. The zfs pool is corrupt, you should backup and re-format, see if it mounts read-only without panicking, you can then backup.

     

    Reboot the server, don't start the array, and type:

     

    zpool import -o readonly=on cache

     

    If OK, start the array, cache will show unmountable in the WebGUI, but the data will be under /mnt/cache, backup and then re-format.

    Why the system do not decrease the transfer speed ?

    Because if the server is flushing the data slower it can cause temporary halts, could also be a network issue, assuming gigabit, transfer should start at 100MB/s while being cache to RAM, then slowdown to keep up with device speed, according to your video it's starting already at 50MB/s, suggesting the network has bandwidth issues, run iperf.
