Later in 2021, MEGA shared their transparency report where they record 230 million registered users storing 107 billion files.

In December 2024 MEGA released their new "S4" (Simple Secure Storage Service) through their Pro Flexi plan.

Initial information suggests that this product supports an S3 protocol compatible API targeting freelancers, startups and individual developers.
