About transferring large image files ( 2 tb's worth)

Is transferring images faster parsing them into smaller groups or not.
I’m using a G Drive Thunderbolt 3.

Images unfortunately are usually the slowest thing to transfer because they are numerous. When transferring a lot of small files it takes longer than single large files.

Dividing it up in sections is just up to you based on how you want to organize the files or perhaps you are worried about something happening during a long transfer then just break it into chunks.
