File operations taking forever
Is there a speciffic reason why file operations take forever on the ReadyNAS? I'm a seasoned *NIX user and normal behavour oof say: mv folder_a ../parent_folder would normaly complete in a matter of a second or two, however on the nas, it seems to want to take forever in doing this simple task. Same goes with rm -rf folder_a (or) rmdir folder_a, again tasks that normally complete promptly on a normal Linux system.
(ps yes i have ssh access enabled, and im trying to perform these tasks directly on the nas under the /data mount for the md array)

Each share is its own BTRFS subvolume. So a move becomes a copy/delete operation. It's fastest to do a cp --reflink and then delete the original.
On deletions - do you have snapshots and/or bitrot protection enabled?
As far as I know, no - bitrot protection isnt enabled on this particular share and i turned all snapshots off. It may be on another share, I will need to doble check, did not know each share was treated as a seperate file system though, I don't see them under mounts (assuming Working Directory /data) only the various nfs share mountd though that would explain why normally instant operations are taking time (As if copying from 2 different disks)

Exactly. But cp --reflink should be as fast as a normal move (the data isn't copied, the new folder entry just points to the same datablocks).
The rm slowdown is unexplained though. Perhaps you should run a balance.
