Reducing Save Time for levels with Landscapes

Anyone have any tips or tricks in reducing Save times with Landscapes?

I am using a 2K Height Map in a Landscape actor in a Blank Level template and it takes a full 5 minutes just to save!
Is this normal?

What are some strategies to get around this?

Definitely need Auto Save turned off!

Using a good computer with an m.2 is your solution.
Savetime on an 8km^2 landscape is a few seconds.

Perhaps saving when my project is on an external SSD is the issue?
Will move my project locally and try again.
C drive using M.2

So yeah that was the issue.
Saving locally around 10 seconds.
When the project is on an external SSD (via USB3 on Windows 10) it takes 50X longer!
I only notice this when using Landscape actors.
