I rarely need fast write speeds with my K-3 but on occasion I need to use continuous shooting either H or M. I have been using the save to both memory card setting and have had the camera really slowdown a bunch. My question is how much is the write speed slowed by having the camera write to two cards rather than writing sequentially to one card then to the second card upon filling the first? I'm assuming that the K-3 will write to one card then write to the other when set up to write the same data to two cards, so if you are writing a 30mg RAW file you will actually have to write 60mg before any other data is written. Has anyone got any experience with just writing sequentially rather than to both? I have never filled up my 32Gig SD cards. My cards are supposed to write close to 90mbps.

Pentax bodies can't yet write in parallel to both slots. What this means is that when you're saving to more than one, the write time roughly doubles. There are some comparative numbers here:

I thought we did this test for the K-3 as well, but I can't find it. In any case, real-world performance follows the same trend, but you can expect slightly faster write times on the K-3 since its files are smaller.
