Dear Proton Community and Development Team,

We, the undersigned, propose the introduction of a "Screwdriver Tier" that allows users to leverage Proton's world-class encryption and UI while hosting the physical data on their own hardware. This "Bring Your Own Storage" (BYOS) model would transform Proton into a secure bridge for private infrastructure.

1) The "Screwdriver" (Self-Hosted) Tier:

Private Storage Nodes: Allow users to connect local NAS (Network Attached Storage), home servers, or massive external drives to the Proton Drive ecosystem via an encrypted tunnel.

Proton as the Interface: Use the official Proton Drive web and mobile apps to browse, share, and manage files that are physically stored in the user's living room rather than the Swiss bunker.

Zero-Knowledge Tunneling: Proton manages the "handshake" and the encryption keys, ensuring the data is never unencrypted on the public web, but the "bucket" remains the user's property.

2) The Hybrid Business Model:

Software Subscription Fee: Users pay a flat monthly fee for access to the Proton "Guard" (the encryption software, the secure tunnel, and the UI) without needing to rent massive amounts of server space.

Infinite Scalability: The storage limit is defined by the user's hardware. If I plug in a 20TB drive, my Proton Drive reflects 20TB of space.

Justification & Benefits:

Market Pioneer: Proton would be the first major privacy company to offer a seamless bridge between "Self-Hosting" (which is currently too complex for most) and "Cloud Privacy" (which is currently too expensive for mass storage).

Reduced Overhead: Proton significantly lowers its electricity and server maintenance costs in the K7 bunker while maintaining a steady, high-margin revenue stream from software subscriptions.

True Sovereignty: This perfectly aligns with Proton’s mission of digital freedom, allowing users to own their keys AND their "granite."

Let us provide the hardware; you provide the Swiss Guard!

This! Even after 5 years we still badly need storage add-ons. All popular brand sell storage add-ons, why not Proton...?

Lots of love for that feature request - I just wrote a similar request before seeing yours!

Unified Storage Add-Ons///////////////////////////

Problem ///////////////////////////

Users who need more storage are often forced to upgrade to a higher plan, even if they don't need the extra features. The pricing for additional storage also varies by
plan, which feels inconsistent and confusing.

Proposal ///////////////////////////

Let all users purchase storage add-ons in 1 TB increments at the same price per terabyte, regardless of their current plan.

Why it matters ///////////////////////////

Users get flexibility without overpaying for unwanted features. Proton gets additional revenue without pushing people toward plans that feel like overkill.

Such an option would be great, especially now with that we have the ability to backup files with the Proton Drive app. The way google offers more space is tempting...

Please include a method to purchase more storage only. Many of us do not have a need for the additional features (and internal cost to Proton) associated with the family plan, duo, visionary, etc. I would love to purchase and pay extra to have access to a plan that provided 5TB total of data for a single user so I could rely on Proton for all of my cloud storage.

It is currently impossible to purchase additional storage space without changing paid plans.
Example: I have a proton mail plus plan, and am reaching my storage limit. I would like to purchase additional storage space (either as a 1-off payment or an increased monthly fee) without having to upgrade to an Unlimited plan. I don’t need the 500 GB of the Unlimited plan and have no use for the other additional features from the Unlimited plan).
That would be very helpful!
Thanks a lot ❤️

I really don't need Duo, I just need the option to upgrade to 1 TB.

It was possible to purchase extra storage before the rebranding. I’d like to see that feature returned across all plans including Visionary. Blocks could be structured something like:

10GB
100GB
250GB
500GB
1TB
10TB

Let me buy as many blocks in whatever configuration I choose to meet my own storage requirements.

While I appreciate a lot of effort went into creating the current individual, family, and business plans, and that storage limits have been bumped up from time to time, we all have different requirements. Photo and video files especially are only getting larger and more of them created. Give us the tools to manage our digital lives without resorting to deleting things as we hit storage limits even on higher plans.

Have 500 GB but would pay to have option to upgrade for more storage without having to pay for other benefits which I do not need or will use.

Hope they offer tiers of storage independently from other benefit plans.

I would have thought 3TB would be sufficient, but I have recently had to back off on what I put in Proton to accommodate the limit. I would like to increase storage, paying more of course, but there is no option beyond 3TB.

I would totally pay more for a 1Tb plan or even buy a set of discreet 1Tb plans. If you're not wiling to accommodate, I think I'll simply build my own NAS instead.

I currently have the Unlimited plan with 500GB of storage on Proton Drive. It would be fantastic if there were options to add independent storage tiers (e.g., 100GB, 200GB, 300GB) as upgrades. These additional storage bundles could stack on top of existing subscriptions—like Unlimited, Duo, or Family—allowing users to customize their total storage capacity without having to switch plans. This would offer greater flexibility for users with evolving needs!

Agreed on this. Makes sense to allow more storage flexibility. The ability to reduce storage in plan options or add storage to a plan seems fundamental.

Note: not talking about per-GB level flexibility but maybe 100GB, 500GB or 1TB tiers.

I just suggest that you add 100 Gb to your VPN Plus plan, or even 500 Gb (1 Gb is very little!) and include much more generous storage in your VPN Unlimited plan I used it for https://kamaikendra.app/

I thought about upgrading my current plan because of waho https://wahoapps.org/ to mail plus but the storage capacity is very low, it is 15 GB which is equal to a free Gmail account

Waiting for this 500 GB+ option for months, even years now, ... do they actually understand they lose a potential high number of clients being such obstinate with this? I really don't understand how hard it could be... moving away anyway.

I have Proton Pass Plus and would like to purchase additional storage for Drive (also to continue using attachments in Pass).

Unfortunately, at the moment you have to subscribe to the Unlimited plan, which includes Mail, VPN, and more.

For cost reasons, I can't and don't want to do that.

Wouldn't it be possible to purchase storage separately?

It's a showstopper. I need to switch to something else if I don't have the oppertunity to buy more space...

Please add this feature… I’d like 3tb but the family plan is overkill.

well overdue
