iCloud strengths + weaknesses

Best Apple integration: iPhone, iPad, Mac, Watch all sync seamlessly. Photos sync excellent. iCloud Drive in Files app. Optimize iPhone Storage = magic. Limitation: weaker on Windows/Android, Google Docs/Office integration not native.

Google Drive strengths + weaknesses

Best Google Workspace integration. Docs/Sheets/Slides cloud-native. Excellent search. AI search Gemini-powered. Limitation: Google scans content (until recently for AI training), USA jurisdiction, less native iPhone integration than iCloud.

Dropbox strengths + weaknesses

Best file sharing UX (link sharing). Best for cross-team collaboration. Smart Sync (selective offline). Limitation: most expensive consumer storage. No native productivity apps. iPhone integration good but not class-leading.

OneDrive strengths + weaknesses

Microsoft 365 Family $9.99/mo includes 1TB OneDrive + Office apps. Best value if you use Word/Excel. Files on-Demand. Limitation: privacy posture moderate, less Apple-native, complex business tier structure.

ProtonDrive strengths + weaknesses

End-to-end encrypted. Zero-knowledge architecture. Switzerland HQ. Bundles with ProtonMail + ProtonVPN + ProtonPass at $13/mo Unlimited. Limitation: newer (2022 launch), fewer features, slower file ops.

Sync.com — under-the-radar

Sync.com Canada-based zero-knowledge cloud storage. Files end-to-end encrypted. Less famous but solid privacy alternative. $8/mo for 2TB. iPhone app available.

iCloud 200GB: $36/year ($0.18/GB/year). Google One 200GB: $36/year (same). OneDrive 1TB: $84/year ($0.084/GB/year). Dropbox 2TB: $120/year ($0.060/GB/year). OneDrive cheapest per-GB if you need 1TB+, plus Office bundle.
