Welcome to 2021!
Today Microsoft announced a file upload increase limit from 100GB to 250GB. This will make it easier to transfer large file sets, making it ideal for 8K video or other high capacity formats.
The uploads are optimized as each file is split into sections that are encrypted with a unique key.
Microsoft also enabled differential sync, meaning the only the portions of the file that have changed are uploaded, reducing significantly upload times, and network usage.
The change will begin to roll out at the end of January 2021 and will be reaching general availability by the quarter’s end.
