I recently acquired a SanDisk 16GB Extreme Pro 280MB/s SDHC UHS-II Card.

As you may, or may not, know the Fuji X-T1 is one of the first digital cameras to support the new high speed UHS-II memory cards.

Needless to say I was quite excited by this factor when the specifications were announced.  Not really from a wedding photographers point of view, but more for the oportunities this kind of write speed may offer sports and wildlife shooters who invest in the X-Series.

So, I did a very very brief test this morning.

In my test, shown in the crude video above, you will see that I shot first with a SanDisk Extreme Pro 95MB/s SD HC I Card (which of course is no slouch in it’s own right). 

The test was configured thus:

  • The X-T1 was set up with the XF60mm macro lens
  • Manually configured and focused so the exposure was locked and had no impact on write speed (not that that should have any impact as far as I’m aware).
  • Camera set to FINE+RAW.  I did this to give it as much work to do as possible.
  • I set the camera to High Speed Burst mode.
  • I shot for 10 seconds (using my iPhone to time), then released my finger.
  • I timed the buffer/write speed there after.

Keep an eye on the little orange/green flashing light to the top right of the camera for the writing to card indication.

The results were:

  • SanDisk Extreme Pro 95MB/s SD HC I Card = 14 seconds (approximately)
  • SanDisk 16GB Extreme Pro 280MB/s SDHC UHS-II = 9 seconds (approximately)

Note:  After recording the video I timed it again against the Youtube clip and it looks like I shot for approximately 1.5 seconds longer before removing my finger for the UHS-II card which indicates an even stronger result in favour of the high speed card.

Of course, remember, the SD-HC I card is not slow by any stretch, but using the high speed card is noticeably quicker and if shooting sport or wildlife, or even some wedding photography, street photography and corporate work, and you need super fast write speed then this is probably the way to go.

I’m currently waiting on a SD-HC II compliant card reader to test the download speed to computer but that is of secondary importance to me at the moment.

As always, please feel free to comment or ask questions.

      That’s pretty good going. I’ve never used an Eye Fi card.

      • They are a bit fragile, and sometimes frustrating but for doing a “faux-tether” to a laptop they are indispensable.

        I shoot jpg+raw and only have the jpg import into Lightroom. The jpgs import into Lightroom in about 3 to 5 seconds each. I can check focus…framing…details that aren’t apparent on the LCD.

        Then when I decide an image or more is worthy of post processing/finishing, then I take the card out and transfer just those raw files to work on.

        But, frequently I find that the jpgs for almost all of what I do are more than good enough.

        I wouldn’t use it when on a trip shooting hundreds of shots…no way..the transfer would take a LONG time.

        But for tethering…it’s perfect.

        • Kevin

          Yes – I agree. Until we get full tethered shooting (or even better, wireless tethered) natively they are a great choice.

  • Yes, it is…and for what it is…it does a good job.

    Before I sign off I’d like to say that I think your photography is really engaging…very pleasing to me. You make the mundane look spectacular.

    have a good day.

    • Kevin

      Thanks very much. That’s really kind.

  • Fred

    If you have not already done so… You should also set the camera to high performance in the power management setting. When setting to high performance the cameras processor and bus runs about 20% faster. Might improve overall speed.

    • Kevin

      That’s already configured Fred. Thanks for stopping by.

  • So why aren’t more pro DSLRs already tethering natively the way the FUJI X-T1 does? Seems like a simple solution. Especially if you dont love CamRanger sorts of wireless.

    • @Alex,
      Fuji’s don’t have native tethering yet.

  • BazzaG

    II’ve been looking forward to getting one of these fast cards but now it appears that my X-Pro1 is not suitable for using them?

    • Kevin

      That’s correct. The X-Pro1 won’t utilise these speeds.
