At this moment we're able to achieve about 1.2GB while replication

I don't think so, at least not with a single volume on the current
version of DRBD, because 1 PiB is currently the maximum gross size of a
single DRBD volume.
Do you advise any different setup?
I would certainly recommend splitting the data if it's possible. I know
that 4k/8k video material can be very large in size, but I guess those
~600 TiB of data is not the working set size for a single movie
editing/finish/effects/... project, or is it?
If it is rather something like an archive, or a single volume with mixed
content, then partitioning by either date or content type could be a
possible solution.
Is it possible to use Linux MD on top of DRBD devices? ie, use
/dev/drbd[0-3] to create a RAID0 array?
Or I guess using them as PV's and then creating a single LV across all
of them?
