Fastest SD Card speed?

Hi all, Strangley I have not noticed a significant increase in image preview speed on my 645Z from the 645D in fact I was able to preview quicker on the D by pressing the play button straight after taking the picture. Anyway are there any known cards that maximise the 645Z performance? I have been using the Lexar 600 speed cards.

The 645Z can take advantage of the fastest UHS-I speeds currently out there (i.e. 95 Mb/s read), but the benefit above 45 Mb/s is minimal. I think any slowness related to image playback is due to the camera's CPU combined with the size of the files. Note that if you use TIFFs, things get even slower so I'd recommend RAW+JPEG.

SanDisk 32GB ExtremePro UHS-II U3 SDHC Memory Card SDSDXPB-032G-A46


I found this not too long ago, check if your camera will be compatible with the memory card. There are very few cameras that can take full advantage of the write speed.

Best of luck,
