Microsoft now lets OneDrive users expand 1TB storage in 200GB increments and launches OneDrive Personal Vault, to protect folders using 2FA, available globally
Microsoft announced two major features for OneDrive back in June: Personal Vault and expandable storage. Both of the features are launching worldwide today.
Context & Ripple Effects
The two features shipping today were both unveiled at the end of June, when Microsoft announced Personal Vault alongside a doubling of its $1.99/month plan from 50GB to 100GB. Global launch means what was a roadmap item is now live for every OneDrive user, closing out the mid-year announcement cycle.
Both additions sit on top of a security arc Microsoft has been building since 2018: the automatic folder backup and protection rollout, then Files Restore with ransomware detection for all customers. Personal Vault extends that from recovery and backup into proactive access control, while 200GB increments address the ceiling problem for 1TB subscribers who outgrow their tier.
First-order effects
- OneDrive subscribers on 1TB plans can now buy additional capacity in 200GB chunks instead of facing a hard cap or a full plan upgrade, directly changing the upsell path for existing paying users.
- Every OneDrive user gains a 2FA-protected Personal Vault folder worldwide, moving sensitive-file protection from an optional setup to a default-capable feature.
Second-order effects
- Incremental storage purchases give Microsoft usage data on exactly how many 1TB users hit their ceiling — the same demand signal that later reshaped its entry-level lineup when the 100GB standalone option was replaced by Microsoft 365 Basic.
- Layering 2FA folder protection onto consumer cloud storage raises the baseline competitors must match on security features, not just price-per-gigabyte, in subscription renewals.
Third-order effects
- If capacity add-ons and security tiers become the standard packaging, consumer cloud storage competition shifts from headline terabyte counts toward trust and granularity — a direction Microsoft has already signaled by bundling ransomware detection, restore tooling, and now vault-style access control into the same service.
- Granular paid increments also foreshadow subscription unbundling: Microsoft's later move to replace flat 100GB plans with a broader $1.99 bundle suggests storage alone is becoming a feature inside larger subscriptions rather than a product of its own.
The trend: Consumer cloud storage is evolving from flat capacity tiers toward layered security features and granular add-ons bolted onto existing subscriptions.
