I have a 25GbE setup using Thunderbolt, kinda similar to the author's. Except that my fan is held together by a piece of string, not a 3D-printed enclosure.

I found that SMB on macOS is just bad. If I try to heavily load it (e.g. by doing mass conversions in my Audible library), it can cause stalls and disconnections.

I managed to find a set of parameters (in /etc/nsmbd.conf) that makes it work more-or-less reliably by trial-and-error: dir_cache_off=yes, file_ids_off=yes, notify_off=yes, mc_on=no.

It's still terrible, though. It's so bad that Linux in a Parallels VM works _better_.

It's always been like this, too! SMB or otherwise. Any company/person that has been using macs long enough has been burned by silently corrupted volumes or etc and has a thorough system of multiple on and offsite backups.

It's not just software companies or home enthusiasts either. There are a lot of ie medical practices or accounting/benefits agencies out there who have sworn off Apple for life after having to spend extreme amounts of money on data recovery to hopefully get their years of records back, usually in a do or die situation like an IRS audit which causes them to discover that their basement was flooding and all of the paper records are destroyed.
