Cloud storage explained: Google Drive, OneDrive and iCloud compared

Most people end up with a cloud storage account without really choosing one. Your phone comes with iCloud. Your work laptop runs Microsoft 365. Your children use Google for school. Suddenly you have three accounts, files scattered across all of them, and no clear idea what any of them actually costs or does.

Cloud storage is straightforward at its core. You upload files to a server somewhere remote, and they stay there safely even if your device breaks or gets lost. You can reach them from any device with an internet connection, and if you set things up properly, your photos and documents back up automatically without you having to think about it. That much is the same across all three services. The differences come down to price, how much free space you get, how well each one works with the devices you already own, and whether sharing files with other people is simple or more trouble than it is worth.

Free storage is where the three services diverge most obviously. Google gives you 15GB at no charge, shared across Drive, Gmail, and Google Photos. For many people that runs out eventually, particularly if you back up photos regularly or have years of email. Microsoft gives you 5GB free with OneDrive, which sounds worse, but matters much less if you are already paying for Microsoft 365, where 1TB of storage is included in the subscription. Apple gives you 5GB free with iCloud, which is genuinely not enough for most iPhone users once your phone backup is taken into account. Apple is quite good at nudging you toward an upgrade.

Paid storage across all three is reasonably priced and broadly comparable. Google’s 100GB tier costs £1.99 per month or £19.99 a year. Microsoft’s 100GB standalone plan is also £1.99 per month, though the more relevant comparison is Microsoft 365 Personal at around £60 per year, which brings the full Office application suite and 1TB of OneDrive storage together. Apple’s 50GB iCloud Plus plan is 79p per month. For 200GB it is £2.99 per month, and for 2TB it is £8.99 per month. Crucially, the 200GB and 2TB iCloud tiers can be shared with family members through Family Sharing, which changes the value considerably if you are paying for a household rather than just yourself.

The single most important factor in choosing between these services is how well each one works with the devices you already use. If you are firmly in Apple’s ecosystem, with an iPhone, an iPad, and a Mac, iCloud is built so deeply into those devices that it barely requires any conscious effort. Photos back up automatically. Contacts, notes, and messages sync across everything. Files you save on one device appear on the others without you doing anything. It works in the background and you mostly only notice it when something goes wrong.

OneDrive has a similar relationship with Windows. If you use a Windows laptop or desktop, OneDrive is built into the operating system from the start. The folders on your desktop and in your documents can be set to sync automatically to the cloud, meaning your files are backed up without any separate app or workflow. For anyone whose employer uses Microsoft 365, OneDrive is also the place where work documents live and where collaboration with colleagues happens. It is genuinely well integrated in that environment.

Google Drive sits in a slightly different position. It works smoothly on Android phones, where it is part of the operating system, but on iPhones and Windows machines it is just another app you choose to install. The reason many people use Drive even on non-Google hardware is the productivity suite that comes with it. Google Docs, Sheets, and Slides are polished, free, and do not require a paid subscription. If you write documents, build spreadsheets, or make presentations regularly, and particularly if you need to share them with other people, Google’s tools work very well and the files live in Drive automatically.

Sharing files with people outside your household is one area where the differences between these services are most practical. Google has the simplest experience for working with people who may not share your setup. You generate a link, you choose whether they can view or edit, and they can open the file in a browser without needing a Google account. This is why Drive has become a default for freelancers and small businesses that exchange documents with clients or collaborators who use different devices and different software.

OneDrive works very naturally within organisations where everyone has a Microsoft 365 account, but sharing with people outside that environment can feel clunkier, particularly if the recipient does not use Microsoft products. iCloud has improved its sharing features over the years, but it is designed primarily for personal use and remains less suited to document collaboration with people you work with professionally.

The honest reality for most people is that you do not need to pick one and abandon the others. The apps are free and the monthly costs at the lower tiers are small enough that having overlapping subscriptions is easy to fall into. What is worth doing periodically is reviewing what you are actually paying for. If you have an iPhone and are paying for 200GB of iCloud storage, and you also pay for Microsoft 365 which gives you 1TB of OneDrive, it is worth asking whether both are genuinely necessary or whether everything you need could comfortably live in one place.

If you do want to consolidate, the decision tends to follow your primary device. Heavy iPhone and Mac users will find iCloud the path of least resistance, and the family sharing options make it reasonable value. Windows users who already pay for Microsoft 365 have 1TB of OneDrive they may as well be using properly. Anyone who shares a lot of documents with clients or collaborators outside a single organisation, or who does not want to pay for office software, will likely find Google Drive the most practical choice.

None of these services is dramatically better than the others in absolute terms. Each one has real strengths that match up well with specific uses, and real weaknesses in areas where the others do better. Knowing which one suits your actual setup means you can stop paying for things you are not using, and start trusting that your files are genuinely safe if something goes wrong with your device.
