After exporting my photos for migration to Synology, Google gave me 95 2GB zip files to download. I tried downloading directly into my mapped network drive, but the speed was super slow. My tip for you is if you are familiar with docker, you can spin up a Firefox container and map your desired network drive to the container. If you download from the Docker container, it will use the NAS’s wired internet connection rather than your PC’s WiFi connection. It is a much faster process, cutting it from days to hours for me. I’m sure most of you would have thought of this right away, but after 25 manual downloads, this was a huge relief for me.
Yes, doing it directly instead of downloading then uploading is generally faster. As is wired instead of wireless.
