That is correct, RADOS nor the RADOS gateway stripes objects.

You will get workload balance if you have a (almost) even spread of 
workload over your different objects.

The dev's might shed some more light on this.

As far as I know you can't do this through the S3 clients but only with 
the rados commands. I also would find it rather weird if you could do 
this as a client.
