For the past couple years, I have transported my 'working set' of video and project data to and from work on an external Thunderbolt NVMe SSD. But it's always been slow when I do the sync. In a typical day, I may generate a new project folder with 500-1000 individual files, and dozens of them may be 1-10 GB in size. The Thunderbolt drive I had was capable of well over 5 GB/sec, and my 10 Gbps network connection is capable of 1 GB/sec. I even upgraded my Thunderbolt drive to Thunderbolt 5 lately... though that was not the bottleneck.
