Features Overview
Google Drive is the world's most popular cloud storage with over 1 billion users. Its 15GB free tier is the most generous mainstream option. Real-time collaboration via Google Docs, Sheets, and Slides is unmatched. Full-text search with OCR and AI-powered organization makes finding files effortless. The tradeoff is privacy — Google can access your files, and your data is stored on US servers subject to US law.
