Uploading from our server not work on it. We have tried it before
storage not truly unlimited, only 2/3TB can be used, Not possible to pay 10$/monthly for 2/3TB size. we upload daily 300GB to 1 TB on MEGA.
you can watch anything image + pdf + videos on mega perfectly & its reliable.
No brand promotion looks like only the site owner hosts his unlimited data for sharing purposes. Maybe some user uses for their work purposes.
Till now I didn't find any benefits to move on it. hope in future if the file host well known on the market we can think to move on it
Looks like The site store data on Hetzner so full data can lose easily by 1 DMCA notice
