How to Check the OneDrive for Business Usage for a User in Office 365?
OneDrive for Business is a Microsoft's cloud-based storage solution that lets you store and work on files that are personal to you. Its similar to any other document library in SharePoint with full control granted to you, so that you can add, update, and delete files or folders in your OneDrive. To get the storage usage on OneDrive for business for a specific user,

• Login to Office 365 Admin Centre, Search and find the user.
• From user settings page, expand the OneDrive for business settings menu and under Quota You'll see the Storage used value!

How about getting OneDrive for Business storage space for all sites? Well, using PowerShell we can create a quick report to check how much storage does OneDrive for business sites have.

#Variable for SharePoint Online Admin Center URL

Connect-SPOService -Url $AdminSiteURL -credential (Get-Credential)

#Get All OneDrive Sites
Get-SPOSite -IncludePersonalSite $true -Limit all -Filter "Url -like '-my.sharepoint.com/personal/'"

This PowerShell script pulls all OneDrive for Business sites.
