Do you mean GB?

Not necessarily related, but SSDs in the parity array cannot be trimmed, and can only be written at parity speed.

If the SMART report is bad enough, you should rebuild it to a new disk. Then you don't need to move anything. If you don't want to replace the disk, then you could move it but that might not be the best solution depending on other details. Copy instead of move would probably be more reliable. And if you didn't replace the disk, then you would need to New Config and rebuild parity without it. You shouldn't keep unreliable disks in the array. Also, you must always have another copy of anything important and irreplaceable. Parity is not a substitute for backups.

You should keep some things on fast pool, appdata, domains, system shares. Mover can move the rest to the array. Doesn't matter if the pool is actually named "cache" for it to cache user shares. https://docs.unraid.net/unraid-os/manual/shares/user-shares/ If you want more detailed advice Attach Diagnostics to your NEXT post in this thread.

Unassigned Devices plugin can read NTFS. Dynamix File Manager will let you work with folders and files directly on the server.

If you don't have parity no need to clear or rebuild. If you want to keep any data from those small disks just New Config with the disks you want in the array, and use Unassigned Devices to copy the data from those small disks to the array.

Does it work now?

Post docker run

And you would still have to rebuild parity to get those empty disks out of the array.
