    Proton Drive, a new service from the same developers behind the highly rated and privacy focused webmail service, Proton Mail, is a security and privacy focused cloud storage solution offering end-to-end encrypted storage and enhanced privacy which is turned on by default!

    As a relatively new cloud storage service (launched in September of 2022), Proton Drive is taking the route of offering their users some of the highest levels of data security and enhanced privacy features which are enabled across the entire service by default. A key component of this enhanced security is the strong elliptic curve cryptography technology which is also backed up by many other useful cloud features including secure file sharing, encrypted file search, advanced multi-factor authentication plus any data kept on the service being subject to strong Swiss privacy and security laws at all times.

    With all of this in mind, Proton Drive looks like a very promising cloud storage solution for anyone taking the privacy and security of their data seriously! Time to sign-up to the service for myself and see the service in action, let’s go!

    Proton Drive Usability

    In this first section of my review, I will be signing up to the Proton Drive service for myself and then testing out some of the key the usability related aspects of the service. This work will cover the actual signup process itself, how easy the service is to configure, use and how well the service functions whilst performing core tasks such as uploading files, sharing them with others and so on.

    NB – Remember, Proton offer all new users to the service a free 1GB of cloud storage with any new Proton Drive account. This is a great way of testing out the service for yourself as well as simply making use of some of the many great features which are on offer for free!

    Signing-up to Proton Drive

    Signing up to the Proton Drive service is, thankfully, very quick and easy and no personal details are requested from Proton during this process (other than a username for logging into the service with and a password, of course). Once submitted, the account creation process only takes a few seconds based upon my own experiences to complete and, best of all, if you already have a Proton account (such as a Proton Mail account as can be seen below) then the new Proton Drive service will already be linked-up in the background and ready to go straight away!

    try proton drive bar in proton mail

    Once signed-in to Proton Drive for the first time, the service will greet us with some informational boxes which show some useful details about the service for first time users. If you are using a free Proton account then also be sure to take notice of the box describing how to get the full 1GB allocation of free storage as this does require a few simple tasks be completed beforehand (as can be seen in the screenshot below).

    Another useful account setting which is available upon first signing-in to the new Proton Drive account is the option to set the default Proton account theme. This can be ignored if you are happy to stay with the default Proton colours, however, there are various other display options including Snow, Classic and Carbon (which is essentially a dark theme for those who prefer such a theme).

    Moving on and with all of the initial settings now configured, the new Proton Drive account will now be ready to use!

    Adding files to Proton Drive

    With a new Proton Drive account now set-up and ready to use, one of the first core tasks for such a service will be the uploading, accessing and then downloading of any files. The upload process begins by clicking on the “New Upload” button found on the left side menu (which will open the Windows Explorer file selection tool) or, alternatively, this can be initiated by simply dragging and dropping selected files over the webpage to begin.

    proton drive review - upload status box

    As can be seen above, whilst uploading files to the service, Proton Drive provides a compressive upload manager tool which, amongst other functions, allows for uploads to be paused or cancelled as well as providing details on any files previously moved using the service. Once any file uploads have completed, these files will then be browsable in the main file window as is the case with many other cloud storage / cloud drive services.

    NB – If you are looking for cloud storage then remember to check out some of our cloud storage guides, this includes a guide to choosing the best free cloud storage and the best cloud storage for photographers amongst others in the guides section.

    With the selected files now uploaded to the cloud drive, downloading them again is as simple as selecting one (or more) items from within the web-based file management tool and then either right-clicking and choosing the “Download” option or selecting the download icon form the top menu bar (as is shown in the image below).

    proton drive review - web download options

    Other options which can be made use of within the Proton Drive web interface itself (as can be seen in the context menu above) include the ability to rename files, create and organise existing files into folders, create sharing links (which will be looked at more in the next section) plus the deleting of files (to the trash can) amongst various other features of the service.

    Sharing Files using Proton Drive

    One of the most important functions of any cloud storage service for many will be the built-in file sharing capabilities. Thankfully, despite being a relatively new service overall, this is an area in which Proton Drive really seem to have got things working really well right from the beginning.

    proton drive review - get link context menu

    Creating a new sharing link begins by selecting the “Get link” option from a file’s context menu (or the “Get link” icon found on the top menu bar when multiple items are selected) and then simply copying the newly created link URL when the sharing configuration box appears (as can be seen below).

    proton drive review - initial sharing link view

    NB – It is important to note that, by default, anyone with access to your Proton Drive sharing link will be able to access your shared files and folders! If the information within these items is in any way sensitive, then be sure to also make use of the password protection and expiration date features provided for additional security as are mentioned below!

    Additional sharing features which can help to enhance the security of any shared links (which, by default, leave shared files visible to anyone possessing the link) include the ability to set password protection for the shared link as well as also specify a time and date in which the link itself will automatically expire and become defunct.

    proton drive review - sharing security options

    Once the new sharing link has been created, it will remain active and in-use until either it is cancelled by the account holder themselves or, if configured, the link expiry date has been reached (at which point it will automatically become defunct). All active sharing links can easily be seen by clicking on the “Shared” section found on the left side menu from within the file browser view at any time.

    proton drive review - sharing download page

    Moving on and with a sharing link now having been created, anyone accessing this link will see a simplified access screen which makes downloading any included files both quick and easy (and without the requirement to create a Proton Drive account for themselves beforehand) as can be seen in the screenshot above.

    Proton Drive Windows Software

    New as of July 2023, Proton Drive have available some new desktop applications allowing the service to be more easily accessible from both Windows and macOS devices.

    proton drive review 2023 - available apps for download

    At just over 68MB in size at the time of my download, the Proton Drive Windows application was a quick download and installation took only a few clicks thereafter. Once installation is complete, the app will ask for the Proton Drive account credentials to be provided to complete the login before then prompting for any folders to be synchronised (backed up) as a part of the initial setup process.

    proton drive review 2023 - windows app selecting folder for backup

    NB – Proton will save up to 10 historic versions of any files for up to 7 days on their free accounts, this increases up to 200 versions for a period of up to 10 years when on any Proton premium plan!

    With any synchronised folders selected, the next step in setting up the app is the specifying of a location for the main “Proton Drive folder”. This is the folder which will be kept automatically in sync with the Proton Drive itself as it also will be on any other supported devices linked to the account.

    proton drive review 2023 - windows app selecting proton drive folder sync location

    Once these initial configuration settings have been specified during the setup process, the main desktop application will become visible and be ready to use. Initially visible on this homepage is information on the device being used, the folders which are currently being synchronised, the synchronisation progress (on the left of the page) plus information on the remaining storage quota found towards the bottom left of the view.

    proton drive review 2023 - windows app homepage view

    Moving on to app settings and these can be found via the main “Settings” link on the left side menu. As can be seen below, the Proton Drive application does not feature many further configuration options with the main parts of the set up completed during the install when the backed-up folders and Proton Drive sync folder location were selected.

    proton drive review 2023 - windows app account settings

    Finally, one final section worthy of mention within the Windows application is the Proton account settings page (as can be seen just above). From here we can get a clearer view of the account storage quota still available as well as being able to manage certain aspects of the Proton Drive account including changing passwords and managing any logged in sessions (although these do, at time of testing at least, seem to simply direct users to the necessary web page for performing such actions as opposed to performing the action from within the app itself).

    Proton Drive Security

    With the key usability aspects of the Proton Drive service now covered, the security and privacy of the service is the next key area to focus on. It is very important to note that one of the key features of the Proton Drive service is that all files and folders are automatically encrypted when being added to the account and are stored in an encrypted state the entire time!

    NB – This special form of zero-knowledge end-to-end encryption being used by Proton Drive ensures that all files are (by default) automatically encrypted before they leave a user’s device for storage on the cloud. Any such files will then remain encrypted the entire time they are in storage and only decrypted upon an authenticated device when the time comes to recall them!

    Proton Drive makes use of highly secure and very advanced elliptic curve cryptography (ECC Curve25519) in order to help ensure they are providing their users with some of the highest levels of data encryption currently available. This is backed-up by all user data being stored in highly secured data centres and the company themselves being based in Switzerland which famously has very strong data privacy laws protecting such companies and their customers.

    It is also important to note that, by default, Proton themselves provide the free Proton Drive account (as with their other services such as the free-to-use Proton Mail service) without requesting any personally identifiable information form their users. This means you could, in effect, maintain maximum privacy when making use of the Proton Drive cloud storage service (especially so when compared to many other services which, at a minimum, will require an active email address to get signed-up).

    proton drive review - account recovery options

    NB – Given that adding an alternative working email address to a Proton account (for recovery purposes) is optional, it is recommended that an account recovery passphrase is therefore generated to help ensure that access to Proton Drive can be maintained in the event a password is lost or forgotten.

    Proton Support

    Proton offer a ticketing-based email support system which can be accessed when logged into any of the Proton services via the top right user menu (found under the “Get help” option). Additional help, support and user guides (including any help provided via the Proton community forums) can be found at the official Proton support portal.

    NB – Proton provide support for all users, however, it is stated that those on premium (paid for) plans ae offered priority support over free account users.

    Proton Drive Pricing

    Proton offer all new users of the service a free Proton Drive account featuring 1GB of cloud storage plus full use of all features and functions including the excellent secure file sharing facilities.

    NB – Initially, the Proton Drive free account is set at just 500MB of storage initially, but this can easily be doubled to 1GB by performing a few simple tasks as will be explained when logging in to a new account for the first time!

    Proton also offer two additional premium plans which, amongst other features, provide more cloud storage within the Proton Drive service as well as boosting the offerings from various other Proton service such as providing more email aliases in the Proton Mail service and additional VPN functionality when using the Proton Unlimited plan.

    The premium Proton account plans are priced as follows:

    • Drive Plus @ €3.99 / month (takes Proton Drive storage up to 200GB)
    • Proton Unlimited @ €9.99 / month* (takes Proton Drive storage to 500GB)
    • Proton Family @ 23.99 / month (3TB total storage shared between up to 5 people)

    * Note that many other enhancements across the full range of Proton services are also available when taking out the Proton Unlimited plan, more information on the full range of account upgrades plus the option to save more on both 12 and 24 month fixed-term plans can be found at the official Proton pricing page.

    Proton Drive FAQs

    Proton Drive Alternatives

    In this section of my review, I will be looking at some closely related alternatives to the Proton Drive cloud storage service. This will be focused on similar cloud storage services which offer a security and privacy focused approach to cloud storage and place an emphasis on making secure use of the service as easy and straightforward as possible.

    Remember, any ratings and opinions given below reflect my own opinions and should be treated only as a guide!

    1) is an excellent choice for anyone seeking an alternative end-to-end encrypted cloud storage service to the one offered by Proton Drive!

    proton drive review - alternative features

    In much the same way as Proton Drive, offers zero-knowledge end-to-end encryption which is enabled on the service, by default, at all times with the main difference being that makes use of AES 256-bit encryption versus Proton Drive which uses elliptic curve cryptography (ECC Curve25519). Other security enhancements available within include advanced multifactor authentication (2FA), use of the highly rated secure file sharing services plus the ability to remotely wipe any lost or stolen devices which have the desktop software installed.

    Proton Drive Review Summary

    It is immediately obvious that Proton Drive is a very well designed, easy to use and competent cloud storage service. A cloud storage service which not only provides a good set of default features to both free and premium account holders, but one which clearly takes the privacy of its users and the security of their data very seriously.

    Whilst the free account offering is undeniably a little on the low side (versus competitors such as Koofr  and pCloud who both offer 10GB for free and MEGA.IO offering 20GB), it should be pointed out that there are no other limiting restrictions on the free accounts. This means everyone can take advantage of the great features within Proton Drive including password protected file sharing and zero-knowledge encrypted cloud storage, for free, should they so wish.

    Whilst the service is lacking still in some areas, for example, not yet having any Windows device software allowing for the storage to be mapped as a virtual drive, it does make up for this with the very easy to use web-based interface and with the very strong user privacy and file security features currently being employed by the service.

    Overall, a highly impressive cloud storage service which gets the basics right and provides excellent security and privacy or all users of the service, great work Proton Drive!
