I wonder if it might be a good idea to collect such experience somewhere in the ceph documentation, for example, a link unser hardware recommendations->solid state drives in the docs. Are there legal implications with creating a list of drives showing effective sustained performance of a drive in a ceph cluster? Maybe according to a standardised benchmark that hammers the drives for a couple of weeks and provides sustained performance information under sustained max load in contrast to peak load (which most cheap drives are optimized for and therefore less suitable for a constant-load system like ceph)?

This would be an excellent idea.
