In general, larger cards are slower than smaller cards. But also in general,newer cards are faster than older cards.

The specs you're looking at are for a Nikon D80, and the performance of different cards will vary with the chipset used in the camera. I don't think you'll find specs that will answer your question for you, and the answer will only come from your own personal experience if then.

Well, I was trying to decide which card to buy for my Olympus E-510.
I currently have the ScanDisk 4GB Ultra II and was picking between the Extreme III 2GB or 4GB. I think the 2GB is 20MB per sec and the 4GB is 30 MB per sec, so that means the 4GB is faster... right?

First, either one will run rings around your Ultra II.

Second, the Extreme III is available in two versions:

Naturally, you could expect the 30MB/s High Performance version to be faster than the conventional version, but both cards are available in 4GB capacity, so if you get the 4GB version, make sure that you get the High Performance version.

The camera's processing speed and write speed to media is likely to be the bottleneck, not the speed of the card, once you get up to newer 133x type cards. To make use of the newest UDMA capable cards, a camera has to support that feature (for example, the E-3 in the Olympus lineup).

As inexpensive as CF Cards are now, I'd look for the best "bang for the bucik" in 133x type cards for your camera.

For example, you can get a Transcend 133x 16GB Card now for only $40.49 plus shipping:

Well, I left before seeing the last two posts. I ended up getting the:

ScanDisk Extreme III 30MB/s/200x CompactFlash Card

That can't hurt, especially since I change camera at least once a year.

Thanks for the great advice.

Oops. My mistake. I was looking at SD cards instead of CF cards.

Yes, the R/W specs for the 4GB Extreme III are 30MB/sec, while for the 2GB they are 20MB/sec.

So, yes, the 4GB should be faster.

Your camera doesn't use SD or SDHC cards.

It uses either xD Picturecard or Compactflash media (one slot for Xd, one slot for CF, no slots for SD or SDHC.

WOW! My Bad! I meant CF, not SD. :?

Now I've got to go back up to the other posts and correct the mistake.

I did say in my first post:

[shadow=yellow][glow=red]ScanDisk CF 2GB Extreme III
or
ScanDisk CF 4GB Extreme III

For burst writing speeds or sheer speed saving as RAW & Jpeg in my Olympus E-510, which is faster? [/glow] [/shadow]
