Save it in the video camera or where?save it to an attached SSD or USB
200 GB is big. Lots of USB and SSD devices will record a few GB then sloowww ddddoooowwwnnnnnnnnnnnnn. Recording can be slow. When you copy to somewhere else, the copy can slow down after a few GB.
Ethernet is about 1 Gbps which is about 100 GBps. I tested many SSD and USB sticks. They can mostly run faster than Ethernet for a few seconds. The good ones run faster than Ethernet for a few minutes, say 10 GB, then slow down.
The microSD card interface in Pi 4 and 5 runs about 50 MBps. Actual cards run far slower. Expect slow copies if the card is involved.
The USB 3 interface in the Pi 4 shares the 5 Gbps, about 500 MBps, interface across both USB 3 ports. The Pi 5 has separate bandwidth for bot USB 3 ports. If your download is from a USB 3 SSD to a USB 3 SSD, it can run up to twice as fast on a Pi 5.
The Pi 5 also has a PCIe connection for an NVMe SSD. I am running mine at PCIe 3 speed. The results are insanely fast compared to everything else. If you are writing large files to a Pi frequently, go for a top model NVMe SSD in a Pi 5 using a PCIe adaptor.
Internet speeds are not as impressive. In our area, all the networks good at times and slow down when 3 billion school kids arrive home to play games.
Ext4 or NTFS or ExFAT. There is a difference in speed for copying 35,000 tiny files but not much for one big file. You hit the hardware write speed after a few GB.
