Data transfer for photographers: how long to back up a 256 GB shoot
Budget at least the 6m 49s USB 3.0 peak-link floor for 256 GB. If you shoot regularly, invest in a Thunderbolt 4 NVMe enclosure to raise the link-rate ceiling and shorten the backup window.
Photographers backing up a 256 GB shoot can start with the peak link calculation. USB 3.0 works out to about 6 minutes 49 seconds, Gigabit Ethernet to about 34 minutes 8 seconds, and WiFi 6 to about 3 minutes 33 seconds at the nominal peak rates. Real storage and wireless overhead can only make those times longer.

Why this matters for you
The peak-link math is a floor, not a promise of application throughput. USB 3.0 is rated 5 Gbps, Gigabit Ethernet 1 Gbps, and WiFi 6 has a higher nominal peak, but the destination drive, protocol overhead, signal quality, and TCP behavior can all slow a copy. For wedding photographers with 500 GB+ shoots, a fast Thunderbolt 4 NVMe enclosure gives the highest link-rate ceiling.
Verdict
Budget at least the 6m 49s USB 3.0 peak-link floor for 256 GB. If you shoot regularly, invest in a Thunderbolt 4 NVMe enclosure to raise the link-rate ceiling and shorten the backup window.
