"Good question. Thought I'd try it to be able to provide some concrete numbers. To cut to the chase, it took me right around 15 minutes for 460 RAW files, each around 30 MB. So a transfer rate of roughly 16.5 MB/s.\n\nThere are going to be areas that produce variation, especially with the external drive and the memory card. So here's more detail of what I did and used:\n\n<ul>\n<li>I loaded a memory card up with DNG RAW files, each of which is in the range of 29MB to 31MB. Cumulative filesize about 13.1 GB.</li>\n<li>I used the FileHub connected to external power and used the RAVPower mobile app to run the operation simply because it has a progress bar so that I could see easily when it was finished.</li>\n<li>For the external drive, I used the new RAVPower SSD that I <a href=\"https://havecamerawilltravel.com/photographer/ravpower-portable-ssd/\">reviewed recently</a>. </li>\n<li>For the memory card, I used a SanDisk Extreme V30 UHS-I card rated for a sequential read speed of up to 150 MBps. There are <a href=\"https://havecamerawilltravel.com/photographer/fastest-sd-cards/\">faster SD cards available</a>, but many of them are UHS-II, which the FileHub can't take advantage of, and the SanDisk Extreme cards are decently quick and very widely used.</li>\n</ul>"
