Memory cards for K3

Can anyone tell me what is the optimum memory card for a K3 ? I want one which will keep up with the frame rate in short bursts. I don't want to buy one which is over specified as that would be a waste of money. I use Sandisk cards as they have never let me down and I have been using their Ultra UHS-1 Class 10 16gb at 7.99 which has been OK in my K5.

From my understanding from the resources I've seen, for most of our Pentax DSLRs, within the Class10 card category, there's little point in paying for more than 40mbps.

Here's an interesting recent Pentax-Specific article on the subject ....link

I must be missing something

The article states the the fastest write speed for cameras in the Pentax range is 45mbps but goes on to recommend a card with a write speed of 90mbps.

Would the read speed be a reason to recommend such a card?

Read doesn't have much significance really ....i mean, who needs lightening speeds just to copy photos to a computer? You can just wait a few extra seconds with no real consequence.

It's the write speeds that matter, and as I said, I get the impression that we won't get any benefit in practical recording situations beyond 40mbps due to the camera hardware limitations.

Considering the differences in price between 30-40mbps and the latest and greatest, I'd gladly sacrifice a smidgen of speed for that cost saving. ..... In other words, it's a waste of money.

Many thanks for the reply, the link clears things up nicely, I was aware that it is the read speed which is shown on the card but I didn't how the write speed was shown.
From the info a Sandisk Extreme should cover it.
