Deleted items (Move to Trash) files, no matter from which partition, they always ended up in ~/.local/share/Trash/.
Therefore deleting big files (like *.iso) would take a long time because actually it moes files to home partition.
I expect Dolphin should not insist the Trash location in ~/.local/share/Trash/. The location should be made at top location of partition where the files to-be-deleted existed. So, it would be a matter of moving file between folder in the same partition.
FYI, I've tried other file managers (Thunar, Nautilus/Nemo/Caja, PCmanFM, Double Commander), no similar problem happened.
Bug still happening on Dolphin v15.04.0.
