Originally posted by Culture I recently bought a second sd card for my K-3.
A scandisk UHS-1 90MB/s speed.
Before this, I had a samsung UHS-1 card. I dont remember the speed.
After adding the second card I realised that when I take a shot and immediately want to review it, I get the hour glass churning. It was really surprising and annoying.
I still could take several shoots without the buffer filling up. But immediately i press play I got the hour glass.
Is this a dual card thing or an SD card thing?

This is an issue which has started being addressed on newer bodies like the K-70 and K-1, but generally speaking if you save to both cards, writing files (and thus the hourglass) will take more time. It's a safe bet that you'll get the best performance with two equally fast cards, otherwise use the faster card for raw files and the slower one for jpegs.
On the newer bodies, the camera unlocks earlier, while files are still being written.
