It’s easy to do a bit of google and find that Sandisk Extreme Pro 95MB/s card is one of the best choices for my OM-D E-M5 camera (or any camera that takes SD card).  However, I’d prefer cheaper cards.  So I bought a Kingston UltimateX 100X Gen 2 Class 10 (SD10G2) 32GB and borrowed a few other cards and performed this test to find out how fast (or slow) it is, relative to price.  (Note: there are many complaints about this Kingston card being slow in amazon)


  • OM-D E-M5 with Firmware 1.1
  • IS Off setting
  • 9fps setting
  • Set to RAW
  • Shoot a watch / clock, hold the shutter until the camera pauses briefly
  • Check how many photos are taken
  • Measure the time between pressing the shutter and the SD write icon disappears
  • Set to RAW + JPEG Large Normal and repeat


Submissions are welcome, but please follow the settings stated above.  If you’re using firmware earlier than 1.1, please upgrade to firmware 1.1 first.
