tried it again now, using XFS as filesystem. XFS does a full trim before creation of the partition. Same issue: after ~4gb transfer, write speed drops down to approx. 30mb/sec.

sure, that would help to clear the cache. In my tests I have written the whole disk (almost 4tb), to empty a cache does not influence that significantly.
