Plenty of things come to mind that can involve a
lot of data
- Docker and other VM images
- Backups
- 4K video editing synced to shared NASes when working from home
- Build and content syncing for gamedev when working from home
4gbit/s is still slow enough for me to spend minutes syncing a mere 100GB, even if I can exclusively saturate that link and not share it with a roommate. That's smaller than some blueray disks and many steam games in their compressed/compiled/processed states for a single platform - no debug symbols, no built object caches, no source assets. It's not uncommon for me to resync a significant portion of that due to mass rebuilds, poorly handled content refactoring, or just switching projects when my local disks (mechanical, SSD, and otherwise) are all full.
