Back in my 20's I built a tool storage box with six drawers. I used butt joins all the way around. Half inch plywood sides attached to half inch plywood bottoms. After 30 years .. the drawers are still in solid shape. Stored in unheated basement. Wanting to build some more drawers. What I understand now is to design a drawer properly a groove is placed in all drawer sides for the bottom to fit into. It would be easier to use butt joints like I did 30 years ago. So wondering why the groove design is better?

Glued and screwed the drawer should be plenty strong. The life you have gotten out of the assembly shows it worked great. With your construction the bottom is not “hanging” from the drawer sides but rather sitting on a shelf/dust frame/other. Any sag would be relative to the support underneath. For future shop projects just consider drawer size. Sag does happen and I have had lab drawers rated to 200 lbs reinforced due to sagging exactly the way Steve suggested. It was probably a 3’ wide drawer with much less than the rated weight.
