20D Compact flash help needed !!!!

Hi All,

i was just wondering......I shoot with a 20D and generally using the RAW+ large JPEG

Has anyone used the 2 gig Kingston Elite Pro card


Is there really a noticable difference in speed between it and say a Sandisk Ultra II card

According to Rob Galbraith's Compact Flash speed database the 2 Gig Kingston Elite pro writes RAWS at 3.876MB/sec and JPEGS at 3.488MB/sec

and the Ultra II's are about 5.473MB/sec for RAW and 4.917MB/sec for JPEG's

The price for the 2 Gig Kingston is $108 shipped and the Ultra II is $175 shipped is the extra $70 really worth it...is the Kingston that much slower ??

Thanks in advance....shkj

You're unlikely to notice the difference unless you constantly fill your buffer. The question with most CF cards is reliability, which is probably fine, Kingston's a good brand. Speed might be a little more important for you, since you shoot RAW+L-JPG, but it should still be fine.

i'm not sure how they rate the two for speed/write/read. My experience is you want around 10mb/read/write to be useable. The problem with the 20D is that it's buffer for raw images is very small compared to say the 1D. I've used the sandisk Ultra II, the ultra III can go past 20mb/sec which is insane. I'm sure the kingston wil be fine. Another brand I always use is corsair. They rate it at 80x and it's very reliable and cost effective.

The problem is not the CF card but the camera. The write speed of the 20D camera is to slow to take advantage of faster CF cards.
Even a Sandisk standard CF card is as fast as a Sandisk EXTREME III or other brand ultrafast CF card if used with yhe 20D.
Like I said: it's the writespeed from the camera and not the CF card that's the culprit.

And the article there also tells you that if the speed in MB/sec is within 10% of each other, the difference is essentially "they're the same"
