I find that it’s rather easy to send a large file via Google Drive, or another solution. Most of them are free and offer good upload/download speeds.
On the other hand, I see people using services that allow people to use services (I won’t name them) that allow sending of tens of GBs (gigabytes) of data.
The downside? The download speed is very slow, it takes hours to download a few GBs of data.
Why do people prefer this?
It’s easier to send files via such services than to use Google Drive / One Drive / Dropbox / other services.
But that „easy” comes with a drawback – slow speed.
