"Unlimited" alternatives to Google Drive, what are the options?

I still have 100TB on Google Drive costing me 5 x £27.10 = £135.50/month but just discovered that I can archive four users & then only pay £5.04 per user per month for these archived users. My monthly cost is now 4 x £5.04 = £20.16 + £27.10 for a new monthly total of £47.26. Crucially I can still access all my files on the shared storage but my monthly cost is now under £50 for 100TB.

Can anybody see the flaw in this arrangement? Are Google going to start nagging me about having archived users with 100TB of shared storage?
