Sysadmin

Hello guys,

We're somewhat struggling with moving traditional file shares to SharePoint Online. Unanimously people recommend moving to multiple sites vs a single one because the ease of management. While I do not doubt that I simply cannot see the logic. The only real limitation I can think of is the amount of items per site where moving to multiple sites would make a difference.

What is easier about managing permissions on for example 5 folders in the root of a single site vs managing the permissions on 5 separate sites?

What I do know is that it is way easier to have my user go to a single site to find their stuff vs 5 different sites (and their corresponding URL's) or am I missing something here?
