has anybody made a test with the SD card ? I have a few older cards, Sandisk Ultra Plus SDHC I, 32Gb, read 48MB/s, Sandisk Extreme SDHC I 16Gb read 45MB/s write 30Mb/s. Adata SDHC 16Gb Class 10. Today I bought Samsung SDXC I PRO+ 64Gb 95Mb/s read and up to 90Mb/s write and it doesn't seem faster then my older cards.
I did a test with all the cards - same setting and of the same scenes, and highcontinuous shooting. Iso 500, 1/1250, f2,8. I took 17 frames in RAW, then the camera slowed down. All the cards almost all the time took 17 frames before it slowed down. When I started shooting, I set a timer when the led light that indicated access to card turned on and when it turned off, I stopped the timer. I did the test with all cards 6 times.
Average Result:
Sandisk Extreme - 26sec
Sandisk Ultra Plus - 25sec
Samsung PRO+ - 24sec
Adata - 80sec
Can anyone do a similar test with another card or do a better test ? Does anybody know the real max writing speed for K-1 ?
I am thinking that I will return the samsung card, because It doesn't make sense to keep it.
I bought it because I need a faster and bigger card for next weekend and I originally was thinking about Sandisk Extreme Pro 128Gb with the same spec as Samsung Pro+, but I couldn't find it in my area, but now I don't know if it will be a waste money to get a fast card when the camera cannot use it.
