Cloud Storage, Explained

Your phone is full, your laptop is full, and every service is offering you more space for a few dollars a month. The catch is that the cheapest headline price is rarely the price that matters — what matters is which ecosystem you're already in, how much you actually store, and whether the service is a backup or just a sync folder. Here's the honest comparison, and who each service is best for.

How it works, in one paragraph

Cloud storage keeps a copy of your files on a company's servers and syncs them to your devices, so the same photo, document or video is on your phone, your laptop and the web. The free tiers are small by design — 2 to 20 GB — and the paid plans mostly converge on the same number: about $10 a month for 2 TB. What actually differs is the ecosystem (Apple, Google or Microsoft), the privacy (whether the company can read your files), how well it syncs, and what happens when you delete something or stop paying. Pick by the devices you own and the files you can't lose, not by the logo.

The comparison

*Google's 15 GB is shared across Drive, Gmail and Google Photos — your inbox eats into it. †OneDrive has no standalone 2 TB plan: 1 TB comes with Microsoft 365 Personal ($9.99/mo, $99.99/yr); the Family plan is now a shared 2 TB pool (see below). Photos only: Amazon Photos gives Prime members unlimited full-resolution photo storage (5 GB for video) — see the note below the table. US prices, checked November 8, 2026.

Service by service

Google Drive — best for overall value

The strongest all-rounder, and the largest free tier that actually matters: 15 GB, shared across Drive, Gmail and Google Photos. Paid plans run through Google One, which Google restructured in 2026 into AI-branded tiers: Basic 100 GB for $1.99 a month, AI Plus 400 GB for $4.99, AI Plus 2 TB for $9.99 a month ($99.99 a year), and AI Pro 5 TB for $19.99 — the cheapest large plan on this page at about $4 per terabyte, with the Gemini app thrown in. Two things to know: the storage-only 200 GB plan is still there at $2.99 a month — what changed in June 2026 is that the AI Plus tier grew from 200 GB to 400 GB — and Google now uses the name "AI Plus" for two different plans, the $4.99 400 GB tier and the $9.99 2 TB tier, so check the storage amount, not just the name, before you buy. The catch is the shared 15 GB: a full Gmail inbox and a phone full of photos can eat the free tier before you store a single document, and the AI bundle means you're paying for Gemini whether you wanted it or not. Best pick if you live in Gmail, Google Docs and Android — and the 2 TB annual plan is the cheapest way to hold that much storage.

iCloud+ — best for Apple households

The invisible one: on an iPhone, iPad or Mac it just works — photos, device backups, documents and messages sync without you ever opening an app. It's also the only service here that can back up the iPhone itself, which is the real reason most Apple users end up paying. Entry is the cheapest paid plan in the category: 50 GB for $0.99 a month, then 200 GB for $2.99, 2 TB for $9.99, 6 TB for $29.99 and 12 TB for $59.99. The 2 TB plan shares across up to six people through Family Sharing, and the price includes Private Relay and Hide My Email. The catches: the free tier is just 5 GB — an iPhone backup alone can exceed it — there's no annual discount (2 TB costs $119.88 a year, where Google's costs $99.99), and it's nearly unusable on Windows or Android. If your household is all-Apple, the decision makes itself.

OneDrive — best for Office & Windows users

OneDrive isn't really a standalone storage product — it's the storage layer of Microsoft 365, and the honest way to judge it is whether Microsoft 365 is worth $99.99 a year. Personal costs $9.99 a month or $99.99 a year and includes 1 TB plus Word, Excel, PowerPoint, Outlook and Copilot credits; Basic is $1.99 a month for 100 GB. For a Windows household that already pays for Office, the storage is effectively free. The big change to know about: in October 2026 Microsoft cut the Family and Premium plans from 1 TB per person (6 TB total) to a single shared 2 TB pool for up to six people — same price ($129.99 a year for Family), a third of the storage for new subscribers. Existing subscribers switch at renewal from May 2, 2027. If you were counting on 6 TB from a Family plan, check before you buy — that deal is gone for new customers.

Dropbox — best for fastest, most reliable sync

The original, and still the best at the one job that matters most: keeping files in sync across devices without thinking about it. Its block-level sync only re-uploads the changed part of a file, which is noticeably faster on large files, and its sharing and version history are the most polished here. The price is the premium: Plus is 2 TB for $9.99 a month on annual billing ($119.88 a year) or $11.99 month-to-month, and the free tier is the thinnest on this page at 2 GB. Family is $16.99 a month for 2 TB shared across up to six people, each with a separate account. The trade-off: you pay more per terabyte than Google or iCloud for storage alone, and files are encrypted in transit and at rest but not end-to-end by default — Dropbox can read them. Buy it for the sync and the sharing, not for the cheapest gigabytes.

pCloud — best for pay once, never subscribe

The only mainstream service here that sells storage outright: Premium Plus 2 TB costs $9.99 a month or $99.99 a year — or $399 once, lifetime, which breaks even against the subscription in about four years. The 500 GB plan is $199 lifetime. The catch, and it's a real one: the lifetime deal is only as durable as the company behind it, and the encryption that keeps pCloud from reading your files — pCloud Crypto — costs extra (about $50 a year, or $150 lifetime). Without it, your privacy is closer to Dropbox than to MEGA or Proton. The free tier is up to 10 GB, and the virtual-drive feature lets you browse terabytes without downloading them to your SSD. Best pick if you hate subscriptions and will keep the account for years — and if you buy during one of pCloud's frequent sales, the break-even comes sooner.

MEGA — best for biggest free tier & privacy

The most generous free tier on this page — 20 GB, no strings — and the only big-name service here with end-to-end encryption on by default: your files are encrypted before they leave your device, and MEGA can't read them. Pro I is 2 TB at roughly $9.99 a month on annual billing (charged in euros, so the exact dollar figure moves with the exchange rate). The catches: the apps and sharing are less polished than Dropbox or Google, the free tier's full 20 GB comes with conditions on some sign-ups, and a service built on privacy means if you lose your recovery key, nobody — not even MEGA — can get your files back. Best pick if you want the most free space and real privacy without paying for it.

Amazon Photos — best for Prime members' photos (photos only)

Not a general file store, but the biggest free-storage deal on this page for the people it fits: Amazon Prime members get unlimited full-resolution photo storage at no extra cost, plus 5 GB of video storage. If your storage problem is mostly a phone full of photos, that alone may mean you never need a paid plan — download the Amazon Photos app, turn on Auto-Save, and the photos are covered. The catches: it is photos only, not documents or general files; video is capped at 5 GB unless you buy extra storage; and if you cancel Prime, the benefit falls back to 5 GB combined. Best pick if you already pay for Prime and photos are what fills your phone.

Proton Drive — best for privacy-first users

From the Swiss company behind Proton Mail and Proton VPN: end-to-end encrypted by default, open-source clients, and no separate encryption add-on to buy — privacy is the product, not an upsell. The free tier is 5 GB; Drive Plus is 200 GB for $4.99 a month ($47.88 a year); Proton Unlimited (500 GB, plus Mail, VPN and Calendar) is $12.99 a month, and Proton Duo covers 2 TB for two people at $19.99 a month. The trade-off: at 2 TB it's the priciest route on this page, and the apps are simpler than Google's or Dropbox's — fewer integrations, less polish. The value pick if you're already in Proton's world, or if you want the strongest privacy guarantee without sorting sensitive files into a special encrypted folder.

Sync.com — best for cheapest 2 TB with full encryption

The cheapest 2 TB on this page — and the only service here where every file is encrypted end-to-end by default, free tier included. Sync.com is Canadian: zero-knowledge encryption on every account, so the company physically can't read your files; servers in Canada under Canadian privacy law (PIPEDA); no file-size limits on uploads; 365-day version history; and it integrates with Microsoft Office, which is rare for an encrypted service. Pro Solo Basic is 2 TB for $8 a month on annual billing ($96 a year), undercutting the $9.99 standard, and the free tier is 5 GB. The catches: Canada is part of the Five Eyes intelligence-sharing alliance, so the jurisdiction isn't Switzerland; there's no native Linux desktop client; and the apps are simpler than Dropbox's. Best pick if you want real encryption without paying the Proton premium — or pCloud's encryption add-on.

iDrive — best for backing up every device in the house

The one service on this page that is a backup service first and a sync folder second. One iDrive Personal account backs up unlimited computers, phones, external drives and NAS devices against a single storage pool — every device in the house, one subscription. Personal is 5 TB: about $70–$84 for the first year on promotion, renewing at $99.50 a year ($9.99 a month); 10 TB renews at $14.99 a month. The free tier is 10 GB. You also get file versioning, snapshots, full-machine image restore, and iDrive Express — they'll ship you a physical drive to seed or restore terabytes (one free use a year). The honest flags: the first-year price is a promotion — the renewal is the real price, roughly 40% higher; and the sync folder (Cloud Drive) is a useful extra, not a Dropbox-grade workspace. Best pick if what you actually need is a backup of everything you own, not another folder that syncs.

Before you decide

Sync is not backup — the one thing to understand

Every service on this page syncs: delete a file on your phone and it deletes everywhere. That's convenient until it's catastrophic — a mistaken delete, a ransomware attack, or a synced folder gone wrong can wipe the cloud copy too. Real backup means a separate copy that sync can't touch: an external drive, or a dedicated backup service. The one exception on this page is iDrive — it's a backup service first, with a sync folder attached, which is why one account can back up unlimited devices. The recovery windows help, but they're short: most services keep deleted files for 30 days (Google Drive trash, OneDrive recycle bin, iCloud Recently Deleted, Dropbox Plus), then they're gone. Version history — the ability to roll a file back to last Tuesday — is also plan-dependent, and longest on Dropbox. Treat cloud storage as the copy you reach from everywhere, not the only copy that exists.

Household plans — where the real money is

One person can get away with the entry plan. A household can't — six phones' worth of photos will eat a shared pool fast. Google One 2 TB ($99.99 a year) and iCloud+ 2 TB ($119.88 a year) both share across up to six people from one pool. Microsoft 365 Family ($129.99 a year) used to be the best household deal at 6 TB — after the October 2026 change it's a shared 2 TB pool, the same storage as Google and Apple for more money, unless you need the Office apps. Dropbox Family is $16.99 a month ($203.88 a year) for 2 TB, but each person gets a separate account rather than a shared pool. pCloud's Family lifetime plan is about $595 once for 2 TB across five people. iDrive works differently: one account, unlimited devices, one storage pool — the household backup rather than the household shared folder. Per person per year, Google One is the cheapest household plan on this page.

How much do you actually need? Check first

Before you pay for 2 TB, look at what you store today. On iPhone: Settings > General > iPhone Storage, and Settings > [your name] > iCloud. On Android: Google One app > Storage. Most people buying 2 TB are storing 200–400 GB — on a 2 TB plan that's 10–20% used, and the price per gigabyte you actually store is five to ten times the headline rate. The honest move: buy the tier that fits what you have plus a year of growth, not the tier that sounds future-proof. Photos and 4K video are what fill storage — documents barely register.

Start here — ten minutes

If you do nothing else today, do this: first, check how much you're actually using (above) and turn on your phone's built-in backup — iCloud Backup on iPhone, Google One backup on Android — because a lost phone without a backup is the disaster this page is really about. Second, turn on the free tier of the service that matches your devices and let your photos sync. Third, turn on two-factor authentication on the cloud account itself — your whole photo and file library sits behind that one login, so a stolen password without a second factor hands it all over. Fourth, check your deleted-files and version-history settings so a mistaken delete is recoverable. Fifth, write down your recovery key or recovery codes somewhere safe — on paper, in a drawer — because an encrypted vault you can't unlock is the same as no vault at all. The paid plan can wait until you know how much you need.

The exit cost — leaving is the hard part

Getting your files into a cloud service is easy; getting them out is the part nobody advertises. Google Takeout, Apple's data download, and OneDrive's download-all work, but moving terabytes takes days on a home connection, and shared albums, comments and version history don't always come with the files. The deeper lock-in is the ecosystem: iCloud holds your iPhone backups, Google holds your Gmail and Photos, Microsoft holds your Office documents. Before you commit to a paid plan, ask whether you'd still choose it if switching cost a weekend — because one day, it will.

What "best for" means — and what it doesn't

There is no single best cloud storage service, and anyone crowning one is selling you a headline. At 2 TB the mainstream price is the same almost everywhere — about $10 a month, about $5 per terabyte — and the differences are fit: what devices you own, whether you need Office or Gmail or iPhone backup, and whether you want the company to be able to read your files. The free tiers are genuinely useful — Google's 15 GB and MEGA's 20 GB cover a lot of people — and most households should start there and only pay when the phone says they're full. The paid plans earn their money on space, sharing and recovery, not on a logo.

One honest caveat: no cloud service protects you from yourself. It can't stop you deleting the wrong folder, and it can't recover files past the 30-day window. The service keeps a copy everywhere you are. Keeping a second copy somewhere it can't sync to is still your job.
