Need a CF card to keep up with the 40d

Hey Guys,
I'm looking for a card that's relatively fast, currently looking at a delkin 450x 66mbs 8gb card, but I don't know much about them. I'm really looking to be able to shoot continuous for as long as possible. I'm open to suggestions, I'm looking for an 8gb card. Thanks

Edit: I'd prefer to get it from BH, as I'm already placing an order there as well.

I'd go with a Sandisk, Lexar or a Transcend CF card. 400x+ would be good (probably even more than you need with a 40D) and can generally be found relatively cheap.

Since the 40D isn't UDMA compatible, anything over 166x isn't really used as the write speed is limited by the camera at that point.

As Nick said, Sandisk, Lexar and Transcend are all good brands; I'd look into one of them. It doesn't HURT to go with a faster card like the 400x if you see a decent price on it, just be aware that the camera isn't using it.

Ah that's a good point.

The price differences are pretty minimal these days, it will help with transfer times from card to computer, but you're right there won't be any benefit while shooting.

Get a Lexar 32GB 400x two pack That way you know a day's shoot fits on one card...and you have a spare.

It does not take a fast card to keep with up a 40D's write from buffer to card.

this is a good thing to NOT discount, too. Not having to wait as long for importing is very nice.

Now given, read speeds on a computer is affected by reader and what interface the reader is using (USB 2, Firewire, USB 3, etc), but it is nice having fast import times.

Either way it's faster than pulling them directly off the camera interface

Absolutely!

Boy is it ever! Once I upgraded to 32GB cards my old USB 2 card reader was killing me! Upgraded that to a cheap USB 3 reader and WOW, it was literally benchmarked around 8 times faster!

So even a 30mb/s card would be sufficient for a 40D right? The Sandisk Ultra II series is a bit cheaper than the Extreme III one so I'll probably go for that.

According to Rob Galbraith tests, the 40D write speeds maxed out with about 133x-150x CF cards

I used a 133x 32GB Transcend with my 40D and it kept up just fine (back then it was a $190 card!!) - would regularly shoot to buffer in RAW. Only advantage to faster memory is for when you get a faster/more demanding camera!

That, or when you've decided you don't like sitting and waiting for the transfer from your card reader to your computer.

go for lexar
