@arcanicanis Interesting! I remembered hearing about the exFAT patent thing a few years back. Never really had a use for it, personally.

For what it's worth, we investigated ZFS when rebuilding that doc server, but we just couldn't get the performance to a usable state. These were Ubuntu VMs within vCenter running on (i believe) a Cisco UCS chassis with some external SAN appliance. It just didn't work out, there was probably some bottleneck somewhere. On that same chassis we had absolute *garbage* performance with an infinidat appliance so I hesitate to place the blame on ZFS.
