I own two SDHC, a fujifilm class 6 8GB and a sandisk ultra II class 4 4gb, and they both work flawlessy with my k-X (including video recordig and burst shoot), i cannot discern between the two when shooting and i don't feel any speed difference.
I think the difference should be obivious when you transfer file from the card to the PC

I tend to agree for my use as well. Add to it the fact that I seldom use burst mode or video, and I'm not really all that worried about class 10. I bought into the speed trip and have a couple of the Sandisk Extreme 30mb/s around, just in case, but the others seem to do just fine.

The latest firmware update has corrected the problem.

it's not that important but does make a slight difference

5.0 out of 5 stars Great card, especially for the price, January 14, 2010

This review is from: Panasonic RP SDW08GU1K - Flash memory card - 8 GB - Class 10 - SDHC
I've had a few Panasonic SD cards and have always enjoyed their performance and exceptional reliability.
I tend to shoot with 8 GB cards mostly because they allow a lot of shooting without the risk of putting all your pictures on one card.

I purchased this card and a SanDisk Extreme Class 10 8GB SDHC card and I will give a quick comparison of the two.

Panasonic Pros:
- Looks great. The bright face and case make the card easier to find when it's buried in your camera bag.
- Has a Memo section on the front and back of the card for labeling purposes. (Although the back part is black)
- Includes a nice-looking sliding case. (Although it is bulkier than the standard cases other SD cards have)
- Priced substantially lower than the equivalent SanDisk.
- Made in Japan (The SanDisk is made in China)
- Very fast read/write speeds.

Cons:
- Not as fast as the SanDisk, although it doesn't claim to be.

The Panasonic states up to 22 MB/s, whereas the SanDisk claims up to 30 MB/s.

The warranty on the Panasonic is 10 years while the SanDisk has a lifetime warranty. But that is pretty much irrelevant since these cards are only usable for a few years before they are too small or too slow.

My comparison test was shooting with my Pentax K-7 which does 5.2 frames per second. I shot JPG 1/100 of a second and the average file size was 9MB. I was able to shoot 53 shots over a 25 second period with about 12 seconds of writing following. This is quite a bit faster than my previous Panasonic Class 6 cards.

With the SanDisk I was able to shoot 67 shots over 25 seconds with 9 seconds of writing afterward. The SanDisk was clearly faster but unless you are doing constant HD movie recording or using burst mode all the time, you would never notice the difference. The Panasonic is more than fast enough for all normal shooting.

I can't say the difference in cost is worth the extra speed of the SanDisk. At the time of this review the Panasonic ($42) is $15-$20 cheaper than the SanDisk.
Overall I highly recommend this card. Like other Panasonic cards I've owned, I expect it will be extremely reliable. "

I was wondering if the new SDHC cards would be compatible with the K20d,

Hi,

I just bought the patriot sdhc class 10 16Gig
and on my k20d, it is damm slow
i cant do bracketing, it fills the buffer up then i have to wait a few seconds to continue, and visualising the pictures also takes more time than with my sandisk extreme III
very anoying
i wonder if a firmware update would help
i measured 17MB/s read on my pc, which is pretty good
havent measured write yet

... dear pentax, would you have a 1.05 firmware for me to enhance compatibiliy with patriot class 10 cards..... thank you

was this the LX (fancy black design) version? if so, there are reports that these have some performance issues. I would guess that you bought them because they are darn cheap. personally, you would had been better off with a class 6 Transcend card.
