Kinda depends on the specifics of the situation. If your external sump was below the elevation of the bottom of your basement, and water could flow relatively easily to the sump, then it ought to be able to keep your basement dry (assuming the sump could keep up with the volume to keep the water table suppressed in that area). There's also the question of where the stump is pumping to...

I was under the impression the external sump had holes on it, so that when the water level reaches a certain level, it’ll just naturally disperse into the soil fairly far away from the house. You do make a good point regarding the volume of water the external sump could handle. I’m not sure what you mean by your last sentence. Are you referring to if I had a basement sump, & it was pumping to the outdoors?. I would likely dig a trench, & install an external sump if water was just pissing onto my lawn. I just wanted to know if my external sump would suffice instead of a basement sump/pump. Kind of a unique situation

Ah, I was thinking you'd have a pump in the external sump.

But yeah, ultimately I think the answer to your question is going to be pretty specific to your situation. It's going to come down to how much water there is and how permeable the surrounding soil is. Probably no real way to know that other than either hiring an engineer or just building it and seeing if it works.
