We currently have a 3 TB storage unit.
Hubby is big on taking videos and photos; especially with his new iPhone 13 Pro Max. As such, we probably need to move up to av4 TB storage unit.
it is the backup device for both our laptops. Also like to have those documents available when we travel.
we do not stream movies from it. But he does occasionally look at videos he has taken on it.
Budget is certainly in the picture.
