K20D write speed

I am currently using Sandisk Extreme-III SDHC cards in my K20D.
Sandisk has now introduced a 30MB/s edition of the SDHC cards, will the K20D benefit from this or is the 20MB/s write speed of the normal extreme-III more then enough for the K20D?

I think a better question would be, is 20Mb/s fast enough for the user?".

It is for me.

I doubt the camera can write faster than the 20+ fps it is capable of in low res anyway . . . but it'd be good to find out.

Let us know.

The price difference isn't that big. I think that I will buy one and compare it with a normal Extreme-III

i would think the 20mb/s would be fine, i had a 30mb/s sandisc for my sony but compact flash, i now use the same as you and i notice no difference.
i expect it will be of benifit for high speed raw shots ie 9fps or more,
and i think the k20d is 3fps raw dng.

With normally shooting you wont notice a diffrence because the camera has a buffer so shooting 6 shots continues will be just as fast with both cards, only if you are really filling the buffer you should/might be able to notice it.
Btw shooting in DNG is faster since the processor of the camera is compressing them less, try it with those please

I think that card won't make a difference on the K20D. Right now, the only camera able to take advantage of the faster speed (as far as I could understand from reading some tech reports from Sandisk) is the Nikon D90, which was designed from the onset to take advantage of the "special" technology involved in those cards. I would like to be wrong, but I don't think so...

I'm using a 16 Gig card,and everything is fine it's a Dane Elec, and as my PC runs on DDR400 Dane Elec memory, I know that it's good kit.

See the 7 Day shop, for amazing prices!

One advantage of going to a higher speed card will be downloading to a PC.

Using a USB2 connection which can run at 480Mbps (60MBps) and a 8GB card using a SanDisk micromate or similar.

With a 20MBps version it will take about 6mins 40secs to download all of the images, but with a 30MBps card it will reduce to under 4mins 30secs. That assumes everything is running perfectly.

Yes, it is frustrating waiting for the images to be transferred, so a 30MBps would stop you chewing too many nails/pencils/hairs ...
