MEGA vs Microsoft OneDrive

MEGA offers 20GB free. OneDrive offers 5GB. That's not a minor gap — it's the difference between actually using your free tier and constantly hitting a wall after a few hundred photos. For anyone who won't pay a monthly fee, MEGA's free tier is the only one that feels like a real product rather than a teaser.

Opening a Word doc from OneDrive and having it auto-save, sync in real time, and support live collaboration isn't a feature — it's a workflow. MEGA has no equivalent. If your work life runs through Microsoft Office, OneDrive removes an entire layer of friction that no competitor can fully replicate.

MEGA uses end-to-end encryption on every file, every time — meaning even MEGA's own servers can't read your data. OneDrive encrypts data in transit and at rest, but Microsoft can technically access your files. For most users this doesn't matter, but for anyone storing sensitive personal or professional data, MEGA's zero-knowledge model is a fundamentally different level of protection.

MEGA's free tier caps how much data you can transfer in a given window — hit the limit and you're locked out until it resets. OneDrive has no such throttling. This is MEGA's biggest practical weakness: the 20GB storage is real, but if you're accessing large files frequently, you'll run into walls that make the free tier feel less generous than it looks on paper.
