Hello
@KacperSochar,
This is the only guidance Microsoft provides with regards to chunk size:
In our testing, we left the default chunk size of 327,680 bytes. For large files that creates a very chatty upload (meaning lots of small part which isn't ideal. For a larger file you can increase the chunk size, but you need to make sure it's a multiple of that 320KB size. You might try a multiplier of 5 or 10 and see how that works.
Cheers,
