Fastest Way To Transfer Files from SD to Computer?

  1. Hello!
    It takes me about 45 minutes to transfer a full 32 gb worth of photos from my Canon T3i with a mini-USb to USB2.0 on my computer. This is a long time to wait.
    Is there a faster way to do this?
    I noticed on my laptop that has an SD card reader that importing 32gb of files only takes about 20 minutes (less than half the time). Maybe I could fancy up some network techniques but that would mean having to recopy the files on Lightroom on a another catalog.
    What are some ways I can use catalogs on this?
    In the end I want to put all my photos on my desktop.
  2. I use an external USB card-reader. They're pretty cheap. If you have USB-3 (and a fast enough card) you can get transfer rates near 90 MB/s). The Lexar USB-3 is (I think) generally considered one of the best.
  3. Agreed. A nice fast card reader is cheap, and should transfer those files in just a few minutes at most. Plus, you're not risking your camera by tethering to an external AC-powered device, and you're not running down its battery for 45 minutes while you move files. Plus, you can shoot on a new card while the previous one is being transferred. Card reader, no question!
  4. I use a sandisk extreme card reader that will download a card very fast, even with large bit RAW files. I use the Sandisk 3 extreme cards as well.
  5. Yep, a direct camera connection to a computer is the slowest way to upload.
    If your notebook has a PC card slot you can install a USB3 card reader. And, of course, you'll need to use the latest speed demon SDHC card (like a SanDisk Extreme Pro). If no PC card slot, you won't gain much with another USB2 reader over your built-in.
  6. If you have a recent generation iMac there is an SD slot right along right side of the screen, just below the DVD slot. Seems pretty fast to me.
  7. I would recommend the benchmarks done by Ron Galbraith at

    The speed of the card will have a huge impact on throughput
  8. LR also makes importing from anywhere to your local catalog quite simple. When I hook up a card reader and start to import, it automatically looks there first to start importing (per my preferences) w/ a couple clicks. You can import from anywhere your computer can see.
  9. Yes, I think the only time I'd connect my camera directly to my PC is when shooting tethered. For file transfers, a USB card reader is definitely the way to go!
  10. I assume you are talking about a desktop computer. If it has USB3 then get a USB3 card reader. If not then you can get a PCI Express card which provides USB3 and also includes a USB3 card reader to fit in the front panel of the computer. I have ordered such a gizmo and I'll report back in a few weeks when I've tried it out.
    If your PC is older and has only USB2, then still a USB2 high speed card reader will improve things and would be a bit cheaper than buying the USB3 expansion card.
  11. Here's what I do. I use a card reader. I open the card on my (MAC) desktop. I drag the file of photos from the SD card to my desktop. I then (& this is important) immediately take the folder that's downloaded and copy it to my drobo (or an external if on the road) for backup. That way I have a pristine backup in case something happens to the copy I've downloaded. I have used no software to this point to do anything. Good luck.
  12. Thank you all for the prompt reply! I purchased the USB 3.0 card reader and the USB 3 PCI express.
  13. If your laptop has a built-in SD card reader, why not use it?
    32 GB is a lot of data. Are you transferring it to an external disk as you read it from the camera? If so, it may still take quite a few minutes, no matter how fast your card reader is.
