[QUOTE="Experimental, post: 1629021, member: 339699"] Just to report back my findings. I did a straight copy from three cards at once. Two cards were from card readers attached over the USB 2.0 ports, and one card attached via the card slot directly in the Mac. On the first test, I used a 160gb (fairly certain it is 5400rpm) mechanical drive that originally came in my 17" Macbook Pro 7 years ago installed in a FW800 enclosure. The second test used the same enclosure, but instead used a Samsung 256gb SSD. The data total from the three cards was 62.5gb of video. The mechanical drive took 24m:50s to copy over, while the SSD took exactly 19m:00s. This set up is as real world as I can make it, using footage from previous events still available on the cards. I ordered up a new 1tb 7200rpm mechanical drive and will re-run the test. Not a bad idea trying 2 cards at a time instead of 3. I'll give that a shot in the future as well to see how it goes. I'll be working on other aspects of the project while the cards are copying down, so getting 3 down at a time would be nice while I'm working on things non-computer related for the project. [/QUOTE]
