I've been working with just NA for many years now, I'm trying to use Model Builder with Iterations to possibly run faster analysis. I'm looking to have many points, and find 60 minute travel time bands for each point. the caviate is that I'm working with 5000+ points, and it crashes my ArcGIS everytime. Any ideas for the model builder set up? then merge all of the polygons back into one geodatabase?

If you are trying to do 5000 service areas of 1 hour each at the same time, then it will run out of memory trying to keep them all in memory. I suggest using the following workaround to use chunking:
