I use the card (32 GB) in the Canon PowerShot G16. For me, the writing speed was critical, so that the images be flushed quickly enough. Performance tests I have now not carried out, but continuous shooting to be flushed without problems. If I set the camera to automatic fire and "footprints", then the 9 x frames / second are written without hesitation on the map. For a JPEG size of about 4.5 MB / picture we are then about at the stated 40MB / sec write speed. The games can I play until the card would be full and the camera is immediately available. For my purposes, and the price more than ausrecheind!
