I'm already way above 1, also no duplication and no balancing (all disabled). changed about every setting I can in settings.json and the only thing i've managed to do is have balancing transfer at the boost rate when not boosted which is still 40% of the drives max. And yes my drives are mounted with mount points or symlinks. currently have 30 and I do not have the 60 ssd's needed to use two per symlink so that is out. also performance has not degraded from when this was a fresh setup on fresh drives so I wouldn't think the MFT would be the problem but I will give it a shot,
