Having just bought a few different SD cards, I've compared their write times in the K-3.
Card ------------------------------ Paid -- Approx buffer clear time -- DNG capacity shown
Sandisk SDSDX-032G-X46 --- £22 --- 23 s ----------------------------- 598
PNY SD32G10HIGPER-EF ----- £20 --- 34 s ----------------------------- 602
Transcend TS32GSDU1 ------ £13 --- 48 s ----------------------------- 594
Method: Hold shutter button pressed until rate slows, then measure the time between releasing the button and the LED turning off.
Since the K-3 has a large buffer that can be written to again before it empies, I dont personally see a need to spend a lot on the very fast cards like 80 or 95 MB/s etc!
