Heads Up on SD Cards

Was in my local "Associated Diaries" earlier today and noticed that they are selling SanDisk 4GB SDHC cards for £9:97...that`s almost 1/3rd the price of the cheapest similar card in "The Holiday Camp"

Prices may vary from location to location (UK)

I'd be interested to see the data transfer rates on that.....

8GB Extreme IIIs should be around £30 / €30 (amazon).

That's Class 2, extremely slow by modern standards.

* Compared to a good fast card: many extra seconds before the camera can take another shot after the buffer is full - after continuous RAW shooting for some models, or Burst Mode for the K20D.

* Failure to record videos in cameras with a video mode.

* Slower downloading from card to computer.

Thanks. So what do you use?

I believe that like most modern technology, to use the fastest transfer rates then you need the latest hardware.
This has been covered here link there are LOTS more topics on the forum about SD cards etc.

Sandisk Extreme III from play.com. Or white Toshiba.

It's doesn't matter so much for the K20D, though, unless using Burst mode. That's specifically Burst mode rather than ordinary continuous shooting.

Card speed made a big difference in my *ist DS and K10D for continuous RAW. I don't know for the K200D.

That's true for the very fastest (30+ MB/s), but not necessarily for a step below that.

Thanks Pete. I've had a quick look at the link Colin gave and in there is talk about download speeds. Most of my cards are Sandisk 4GB SDHC, and I don't seem to have issue with them in either the K20 or K200. However can you tell me the time difference in transfering a full card, onto the PC, between your type of card and mine?

I think a faster card can roughly halve the time of a download, but sorry I don't have any slower cards to test at the moment. Hopefully someone else can post some more definite info.

Are we talking download rate/transfer rate from optical sensor to storage or from card to pc?.

I take that back,I`ve just read the comments on the link....I presume "speed" depends on your subject.

Yes but also on your card reader many can't handle the faster 30MB/s cards.

For speed a Class 2 means 2MB/s to 3.9MB/s so compare that to a 30MB/s then well that can mean a difference of 10 seconds instead of 100 seconds but the world isn't so black and white but there really is a difference between them but it depends different factors.
I think it's save to say that the 30MB/s cards are roughly 6 to 8 times as fast as a class 2 card.
