Fastest SDHC the K-3 can handle

**crewl1** · 12-13-2013, 02:54 PM

I must have misunderstood then because I read Ron's statement as referring to time to clear buffer being similar between the two cards.
That happens a lot

I don't care if my camera does not take full advantage of the card since I prefer fast cards uploading with my USB 3.0 card reader. I paid $18.95 with free shipping for two 16GB 94MB/s cards from B&H this past year or less than $9.50 each that shows a steady 80+MB/s read when uploading.

Is USB 3.0 faster than a BUS Card Reader?

Yes...and all current flash cards:

and even when reading off a hard drive...

Are those the Sony's? If yes as I understand it the write speeds are 45mb/s, but at $9.50 they were a steal.

Yes they are and 45MB/s write is fast enough for any camera I use.

The statement I can see about buffer performance is:

I only got one extra image with the faster card, so that is about to be the margin off error on the measurement.

But the faster write speed doesn't help much during the burst. It's after the burst that I'm interested in here. That's covered in the PF review:

Pentax K-3 Review - Performance and Burst Mode - PentaxForums.com
Time to clear full buffer
(measured from end of burst)

K-3 RAW 19s 33s

Where 19s was for the SanDisk 95Mb/s 32GB Extreme Pro SDHC Class 10 UHS-I

and 33s was for the SanDisk 45Mb/s 32GB Extreme SDHC Class 10 UHS-1

If using JPEG, the buffer depth looks quite impressive:

Number of frames at max. FPS

K-3 JPEG Fine 52 43

Because the image files are smaller, the write speed becomes more significant for the effective buffer depth, as the buffer can partially empty during the burst.

and the full buffer clearance speed is better:

K-3 JPEG Fine 12s 19s

Dan.

Well I did notice that test at the time, but didn't spend any attention to it.

So did a quick test with jpg:

Both cards in the K-3 had equal performance with jpg. I have SanDisk 95MB/s and 45MB/s cards and both made 67 jpg images at full resolution and 3 star quality. Both buffers cleared in 31 seconds (with margins off error for that being a second).

P.S. or I got ripped off with my fast card!

Up till now I felt the same. We are interested specifically about maximizing K-3 potential in this sub-forum though

So what exactly are you looking for ?

Not my thread but as in the title: fastest write speed that the K-3 can handle.

You are missing the point. It's not about the card, but the real life performance off the card inside the K-3.

So are you looking for something more that what has been posted on PF ?

My findings where different then the test Adam did. No idea if Adam got it wrong, or someone sold me an expensive fast card that just holding a sticker saying it should be fast!

Or knowing the actual limit of the gear. Nothing wrong in discussing what's been already discussed IMHO
