new memory card

Duckys54

So with the sandisk rebates I'm going to be getting two 4GB ext4 CF cards but I recently heard of something called Ducati. Could anyone give me a brief overview of what this is?

Well, their Sandisk page pretty well lays out their intent - a fast card - 45MB/sec is not chump change.

By comparison, the Extreme IV are advertised at only 40MB/Sec.

But, that's only part of the story. You also have to look at the device into which you are inserting your cards. Putting either of these cards into the original dRebel (the 300D), for example, would be like putting F1 racing slicks on a Yugo. Just doesn't compute.

It might help to take a look at some test results for various cards in your 40D. Doing so will help you avoid buying more card that your camera can effectively use. Also, you may find that there are cards by other manufacturers that perform as well or better for your application at a quite lower price. It comes down to a question of how fast to you need the card to be. For example, Art Scott has sold me on the Transcend cards - nearly identical performance (especially when you add in the human factor - delay between shutter presses) in my application but at a substantially lower price. I'm not trying to sway you one way or the other - just attempting to offer up alternatives that you may not have already considered.

BTW - I really don't want to sound mean and nasty (though I know how to do that very well ), but did you try to do the research yourself? Google is your friend! I found the above information in less than a minute. Typing this whole thing up and including the links took me less than 5. Something to think about.

Okay SCOTT BLAME ME FOR SAVING YOU MONEY....

Remember also that when companies start using the names of other companies for their products....it is a promo gimmick......SD could have just as easily called the Turbo Extreme or something......but I remember there was some sort of deal between SD and Ducati Motorcycles at the time a few years ago........

Memory card companies do not want to readily tell you exactly how their cards perform any more......I got my info directly off the mfg'ers sites and some I had to actually ask why they did not publish this info openly and got no answers except for the data I was seeking.......the Transcend Industrial card has better numbers for hot /cold working temps than the SD cards but it lacks speed (the last time I looked it was a 45X card) but it is a monster when coming to it working temps.........

I was a diehard Lexar fan until I ran across Transcend and found I could get faster and larger cards for less.....the one thing lexar has that Transcend doesn't is recovery software and it recovers raw, jpeg and tiffs.....individually or all at once...but it renames the files (small mater of renameing in PS as you want)........

rignt now I have been buying 8gb transcends(133X) for 19.99 off new egg and will continue with them unless I find SD or Lexar for less for the same type of card........

I am however one that would not buy anything because of its cool name or such.......all I care about is dependability.......so if transcend came out with a Lamborghini Card and it had unheard of out of this world proven specs.....I would steer clear of it...but that is just me......

Make sure that your camera will use the card to it's best....... and read speeds aren't what to look at......but the write speed is critical making that a touch faster than you current camera can utilize is fine if you plan on upgrading in the near future.

Good luck

Even if your camera cannot fully use the speed of the fastest cards...
it is nice to have that extra speed when downloading off the card to the computer. Waiting on pictures to download to the computer is like watching paint dry! The sooner it is over the better.

Just my $0.02.

This is true and that is way I have the Extreme IV CF (firewire) Reader (SDDRX4CFR) - this thing really screams when compared to the USB 2.0 CF reader I also have.

That's fine. I had just got out of class and was going to swing by a photostore to see if they hard any 4GB ext IV memory cards for sale and he mentioned something about ducati. I didn't know what he was talking about and couldn't understand him and I had marching band to go to so I figured I'd ask you guys because I knew you were helpful.

Thank you for pointing me to that Rob Galraith site, though. Never heard/seen of it. After looking at it, originally I was going to get some 4GB for cheap because of the rebates, but now I'mm considering a bunch of 2GB because they write a bit faster. But I'm wondering how much different is 10.91 (2gb et iv) vs 10.64 (4gb ext iv)? Is it enough to matter?

the ducati cards are fast; no doubt about this. however, i don't believe that you'd be able to take full advantage of their speed in your camera. unless you do a lot sports shooting; which the 40D isn't exactly the prime candidate for, i think you'd be overspending on the ducati cards.

lexar UDMA and sandisk IV cards are both top notch IMO. it should be noted that delkin also makes really quick cards; albeit a bit on the expensive side as well. personally, i'm a fan of calumet's prospec-branded cards. they're UDMA but not quite as fast as the sandisk IV and top end lexar cards. however they do offer up a competitive price point and have [knock on wood] been very good to me. i've got varieties ranging from 4GB-16GB.

In a word - no. if you do the math, you are looking at a 2.5% difference in speed here. When you add in the effect of the camera buffer - in real life you won't see the difference. When it comes reading the card (downloading to your computer), assuming similar speed differences, you are looking at a difference of, at most, 10 - 20 seconds per card.

As for the 2GB cards in a 40D - if you are shooting RAW, you are looking at getting about 100 images on a card of this size. This could mean swapping out a card when you would rather not - something to think about.

4GB card will fit a DVD±R/RW and seems appropriate for the 40D RAWs.

Well I decided to get two 4GB extreme IV's and I used the money from the rebate to help purchase a Sandisk Extreme Firewire CF card reader

Thank you so much for everyones' help and input!

That'll work and I think you'll be quite happy with your purchases.
