Pentax K5lls & Memory Card Speed

I think the cameras processor will be the limiting speed factor well before the write capabilities of these cards. Any card with a rating of 10 now will be easily capable of copying photo files faster than the camera delivers them, as well as continuous HD video recording.
you're shooting RAW, so make sure you switch off the in-camera corrections such as shadow & highlight distortion & CA. These will all cause the processing to take longer as the effects are written to the embedded JPEG (which displays on the LCD). Just deal with these issues if needed on the computer later.
It will not affect the cards writing speed, but will mean the camera will take longer to finish the processing and send the data to the card, and that will delay you in taking more shots straight away.

FYI: When you see cards boasting 400x and 600x (or even higher) they are referring to 'read speed' - not write.

I had the same problem, I have loads of different cards, all different speeds and recently I purchased a couple of Transcend 32gb 600x so I wanted to check if they were worth keeping.
Download this and run it ... the Transcends are quite a bit faster than the rest.
You going to Riat Rob? I was too late to buy a ticket for Saturday so I'm going to try out the K-3 in a farmers field

That's interesting. I guess they want to quote the highest numbers they can find. I wonder what is the use if 'read speed' ? This would be how fast you could copy data off in a computer saving to hard drive or playing video straight from the card ...nothing of much significance frankly. But the class 10 standard is a kind of benchmark isn't it, but more than enough for our cameras buffer and write capacities I believe?

Yes, it's deceiving to anyone who just looks at numbers and relates them to how fast the card can store data sent from the camera (which has the last word in how fast it can push data onto a card).
As you say, Class 10 is the type to buy when you want the best performance from modern devices.

The K5 i/ii/iis does fully use the technology (ie UHS)
K5iis and a couple of lenses.

Has anyone else used any of these cards on the K5lls and is there any card which is significantly better or are they all about the same speed-wise? I'll be shooting in the RAW format.
