Consumers and businesses continue the trend of reducing their need to rely on local storage hardware and infrastructure by placing files and applications in the cloud.
Given the multitude of cloud storage providers out there, one has to wisely choose a provider who will offer the maximum amount of low-cost storage and bandwidth, while still keeping your data safe.
This list represents our top picks for cloud storage: most offer a free tier allowing you to see if they're right for you before handing over any hard-earned cash. Business users will need to consider carefully what their needs are as terms and conditions as well as quality of service is likely to differ significantly.
Go straight to your desired option through the jump links below
Veteran cloud storage provider
The Granddaddy of cloud storage, Dropbox offers a rather measly 2GB of free storage, but this can be increased up to 16GB free of charge by linking your Dropbox to social media and referring friends to join the service.
Dropbox Business subscriptions allow users to collaborate on work as well as giving each person unlimited space in a personal Dropbox account. There are also enhanced features for file recovery and versioning, and an add-on for Gmail. Business pricing starts from around $12.50 per user per month (£10, around AU$16.50), or you can give it a go for free with a 30-day trial.
Price: 2GB free. 1TB for $10 a month (£6.58, around AU$11) with Dropbox Plus or 2TB for $19.99 a month (£15, around AU$27) with Dropbox Professional, which has some added extras.
A smart option for Google fans and G Suite users
Google Drive is a natural choice for owners of Android devices as it's already integrated, but users of other platforms may appreciate the generous free storage too. You can also store high definition photos on your mobile phone with companion app Google Photos, and make use of Google's own office suite (now known as G Suite). Also, upgrading to paid Google Drive plans is now called Google One (although it might not yet be available, depending on the region).
Downsides include the fact that the web interface isn't very easy-to-use, although Windows and Mac users can download a desktop app to drag-and-drop files easily.
Price: 15GB free. 100GB for $1.99 a month (£1.59, around AU$2.50). 200GB for $2.99 a month (£2.35, around AU$4.10). 2TB for $9.99 a month (£8, around AU$13). 10TB for $99.99 a month (£74, around AU$130).
Puts a premium on security
With an insanely generous free tier and a simple drag-and-drop interface, New Zealand-based Mega is one of the cloud storage heavyweights. There's a handy mobile app to allow you to upload files and photos, as well as sync clients with desktop machines.
Mega claims that all data stored in its cloud is encrypted on your device before it reaches the firm’s servers. As the company has released the source code to its sync client, experts can check that there are no vulnerabilities.
Price: 50GB free. 200GB for $6 a month (£4.50, €4.99, around AU$7.50). 1TB for $12 a month (£9, €9.99, around AU$16). 4TB for $23 a month (£17, €19.99, around AU$30). 8TB for $35 a month (£26, €29.99, around AU$46).
Backed by Microsoft and ideal for Windows users
OneDrive (formerly SkyDrive) is integrated into Windows 10's file explorer. You don't have to download an additional app – it's there to use out of the box, which is obviously very convenient for those who have made the jump to Microsoft’s newest operating system.
Microsoft's Photos app can also use OneDrive to sync pictures across all your devices. There's an app for Android and iOS devices, and there's even one in the App Store for Mac users (although it has received mixed reviews).
Price: 5GB free. 50GB for $3 a month (£1.99, around AU$4). 1TB for $8 a month (£5.99, around AU$11). 5TB for $11 a month (£7.99, around AU$14)
Apple’s competitively priced cloud storage locker
If you want to back up your iPhone to iCloud, you'll need more than the free 5GB allowance Apple gives you, but compared to rivals iCloud prices are very reasonable.
The Mac Finder app integrates iCloud Drive, where you can store any files you wish. Documents created in the iWork office suite are also saved to iCloud and can sync across your devices. Windows users can also sync their files with iCloud Drive using the official client, and access the iWork apps on the iCloud website.
Price: 5GB free. 50GB for $0.99 a month (£0.79, AU$1.49). 200GB for $2.99 (£2.24, AU$4). 2TB for $9.99 (£8, AU$13)
Well-known service with some powerful business options
Box's website currently seems to be pushing its Business plans as clicking ‘sign up’ takes you to the pricing page where for $15 per user (£11, around AU$19) you can benefit from advanced collaboration options and unlimited storage. But there is a 10GB free option, too.
As Box has been around for a while, it is supported by a number of mainstream apps such as Google Docs and Office 365. The Box Sync client is available from the Downloads page for Mac and Windows, plus there's also an official Android client.
Price: 10GB free. 100GB for around $10 a month (£7.50, around AU$13)
DIY cloud storage solution
NextCloud isn’t an online cloud storage provider itself, but offers free software to download and install a cloud storage service on your own server. Using a server on your home network for cloud storage is much faster. You can also enable encryption and make sure the information never leaves your home network, which is far safer.
If you've no server or IT experience, you can even purchase a preconfigured NextCloud Box from the website which comes with a 1TB hard drive and will work with an inexpensive Raspberry Pi board to keep your data synced.
Price: Free to install and use. Self-hosting so storage costs vary. NextCloud Box is $79.99 (around £60, around AU$100), although it sold out in most locations, but you might find some on their site.
A ‘zero knowledge’ cloud storage provider
SpiderOak is part of a new trend of zero knowledge cloud storage providers. The website claims that after installing the client your data is encrypted before syncing. Unfortunately since SpiderOak hasn’t made the client source code public, there's no way to confirm this.
The SpiderOakOne client is available for Windows, Mac and Linux as well as Android and iOS (although, both Android and iOS are read-only apps, meaning you can only view files, and can't upload or sync anything). You can also log in via the web interface but privacy lovers may prefer not to as it exposes your password to SpiderOak employees.
Price: 21-day free trial. 150GB for $5 a month (around £3.75, AU$7). 400GB for $9 a month (around £7, AU$11.50). 2TB for $12 a month (around £9, AU$15). 5TB for $25 a month (around £19, AU$33)
Storage solution which extends to cover network drives
IDrive offers continuous syncing of your files, even those on network drives. The web interface supports sharing files by email, Facebook and Twitter. Cautious or click-happy users will be pleased to hear that files deleted from your computer are not automatically deleted from the server, so there's less danger of removing something important accidentally. For photos, you have a neat facial recognition feature that helps you automatically organize them.
IDrive also offers IDrive Express – a service whereby if you lose all your data they will ship a physical hard drive out to you, allowing for the swift restoration of all your backed up files.
Price: 5GB free. Personal: 2TB for $52 a year (around £40, AU$66). Business: 250GB for $74.62 a year (around £56, AU$98)
Ideal for those storing large media files
While some bandwidth limits apply, there seems to be no limit to the size of files you can upload, so feel free to sync large media files with pCloud.
The service is available for all desktop and mobile platforms – users can also log in via the website. The company itself is registered in Switzerland which has strong privacy laws, and you can also pay a premium of $4.99 a month (around £3.75, AU$7) for pCloud Crypto to lock (and unlock) individual files with passwords.
Price: Up to 20GB free (You start with 10GB and can increase that by referring people). 500GB for $3.99 a month (around £3, AU$5). 2TB for $7.99 a month (around £6, AU$10). Lifetime plans are also available: 500GB for 175$ (around £131, AU$230). 2TB for 350$ (around £262, AU$460).
Best free cloud storage
Heavyweight cloud storage offering tied in with G suite apps
Free storage allowance: 15GB (expandable)
If you're a Google user, you already benefit from Google Drive integration, such as the ability to save email attachments from Gmail. However, anyone can sign up for the free cloud storage, even if they don't have a Gmail address, by creating a new Google account. Google is also in a process of releasing Google One as a sort of substitution for Google Drive, although depending on your region it might not be available yet.
With 15GB of space for new users, Google Drive is one of the more generous cloud offerings, and there are occasional ways to boost this capacity free of charge. The catch is that this Google storage space is also shared with a user’s other Google services including Gmail and Google Photos.
Mobile apps are available to allow easy access for iOS and Android users, and Google’s Backup and Sync desktop app lets you synchronize files from your PC to the cloud. Google Drive also includes online office tools for word processing, spreadsheets and presentations which can makes sharing files with others effortless.
A smart service with a slick online interface
Free storage allowance: 10GB (expandable)
You might not recognize the name, but if you're looking for a decent chunk of cloud storage free of charge, pCloud could be just the ticket. To kick things off, you're given a fairly generous 10GB to play with, and there's a bandwidth allowance of 50GB of downlink traffic per month.
While we're primarily interested in the free version of pCloud, note that you can upgrade to 500GB of space for a monthly plan of $4.99 (£3.70), or 2TB for $9.99 (£7.50) a month – both of which are great deals for storage. You also have annual and lifetime plans, which are a cheaper option in the long run.
The initial 10GB free offering can also be expanded up to 20GB via an additional 4GB for completion of offers, as well as referrals that add 1GB each. It’s also worth noting that pCloud offers well-designed desktop and mobile apps that supplement the website for seamless integration into a user’s workflow.
With no limit on file sizes, and simple sharing options, pCloud is a great way to send large files to friends and colleagues – it's even possible to share with people who aren't using the service themselves. Add in decent streaming options and a neat online interface, and pCloud is well worth a look.
Another sterling storage solution, particularly for Windows users
Free storage allowance: 5GB
Coming from Microsoft – a company with plenty of money to throw at the cloud – it's a little disappointing to find that OneDrive doesn’t include more space free of charge. Free users get a mere 5GB of storage, although it's relatively inexpensive to increase this to 50GB.
If you have Office 365, you'll automatically get boosted to 1TB of space, but not everyone wants an Office subscription.
Like Google Drive's appeal to Google users, OneDrive will be a good fit for anyone who is committed to using Microsoft's services. There's neat integration with Outlook.com, for instance. OneDrive also ties in nicely with Windows 10, and there is a selection of reasonable mobile apps to facilitate access on the move.
It's possible to share files with other people even if they aren't OneDrive users (complete with customizable permissions), and the ability to edit files online without downloading them is a welcome touch.
Another big name with some great support for third-party apps
Free storage allowance: 2GB (expandable)
Dropbox is a stalwart of the free cloud storage world, with a web interface that remains streamlined and easy-to-use.
Despite its popularity, Dropbox actually has one of the least generous free packages for new users (just 2GB), but there are various ways to boost this space without paying, including inviting friends to join (you get 500MB per referral up to 16GB), completing the Getting Started guide (250MB) and contributing to the Dropbox forum (which elicits 1GB per 'Mighty Answer' provided).
DropBox really comes into its own when you start delving into the service’s extra features. There's a great collaborative working tool called Dropbox Paper that acts as a group workspace, and – if you install the desktop app – you can back up photos automatically. The File Requests feature also allows you to request another user to upload a file to your Dropbox account.
There are desktop apps for Windows, Mac and Linux, and mobile apps including Android, iOS and even Kindle. This gives Dropbox broad appeal, as does the support for third-party apps and services.
The web version of Dropbox lets you edit files without needing to download them, and really the only thing that counts against the cloud storage service is that most alternatives offer more space to free users.
A highly experienced cloud storage operator
Free storage allowance: 10GB (expandable)
MediaFire has been around for over a decade, and those years of experience really show. You're given 10GB of free space initially, but you can boost this by an extra 40GB through activities like referring friends and following MediaFire's social media accounts. Few people would disagree that 50GB of free cloud storage is impressive. Free accounts carry ads, but this is a small sacrifice to make.
There's support for large files up to 4GB, and the sharing options are very impressive, even allowing sharing with non-users.
The web-based interface is excellent too, and MediaFire offers mobile apps for convenient uploading and downloading on iOS and Android. These make it easy to access files you're storing in the cloud, and include convenient features such as automatic photo syncing.
Best business cloud storage
Ultra-secure cloud storage with a simple interface
SpiderOak is a collaboration tool, online backup and file hosting service founded in 2007. The platform allows users to access, synchronize and share data using a cloud-based server.
The company places a strong emphasis on data security and privacy. They offer a cloud storage, online backup and sharing service which they claim uses a ‘zero knowledge’ privacy environment. This means the client is the only one who can view all stored data. Not even SpiderOak themselves have access to your data.
SpiderOak’s main focus is on privacy and security. As a result, the tool itself has a very basic design. This makes the admin console and all central device management very straightforward to use. They also include a handy drag and drop feature for organising files.
From the centralized device management dashboard, users can access settings for all applications such as backup selection and sharing. The dashboard also allows users to manage their accounts, set group permissions and gain insight into usage.
Prospective business clients will need to contact SpiderOak’s Sales Team directly to obtain a quote. 500 users minimum is required.
Online commentators have observed that SpiderOak lacks many of the collaboration tools available from other cloud storage providers.

The extra security offered by Tresorit makes it relatively expensive compared to other cloud backup solutions. However most users will probably appreciate the greater piece of mind and extra features offered by Tresorit.
Generous storage paired with flexible sync tools
Egnyte was founded in 2007. The company provides software for enterprise file synchronization and sharing.
Egnyte allows businesses to store their data locally and online. All types of data can be stored in the cloud, whilst data of a more sensitive nature can be stored on servers on-premise. This makes for better security.

Reliable and reasonably priced storage from a leader in online storage
Dropbox is one of the oldest cloud storage providers. It was founded in 2007.
To date it is one of the simplest storage providers to use. Dropbox can be installed on most computers or devices and syncs easily between apps. The app can store almost any kind of file while never having any issues with compatibility. You can drag and drop files into the desktop app with ease.
You can also share files with other users easily through links. These can be shared with users who don’t have a Dropbox account.
As Dropbox has been around for a long time it integrates with most other apps such as MS Office and Slack.
All files and folders can be shared with other users even if they are not part of your account. These users will be limited to their own plan's storage limits.

The dashboard is simple and easy to use. From here, admins can see how many team members they have as well as any pending invites. You can restrict sharing, and allow/block commenting as you see fit. The dashboard allows you to access settings and to monitor usage.
Dropbox offers a 30-day free trial which asks for your payment details. Your plan will automatically upgrade after the trial at which point your card is charged.
The ‘Standard’ plan starts at $12.50 (£9.71) per user per month starting at 3 users and includes 3TB storage.
The ‘Advanced’ package begins at $20 (£15.70) per user per month with unlimited storage.
