Sandisk Ultra II or Extreme Class 10?

[Robbo]

I just bought myself a new lens and hoping to do some more outdoor sports stuff etc, which I would like to be using the continuous shoot at times.

Shooting in RAW on my camera, stores 6 in the cameras bank. Would I get away with the Ultra II at 15mb/s or would I need the Extreme 30mb/s If I was shooting say 3-4 burst then snap snap snap then burst again (if that makes sense) ?

Hi

A friend has the 450D and he can shoot 25+ in a burst (of Jpeg) without buffering the camea and using a Sandisc 15mbs card (think it's an extreme, but it is def 15mbs card). He's not tried RAW yet, but I would have thought should be a similar deal as the camera can only write at a certain speed,

Hope this helps

I think thats the ultra II at 15mbs, the extreme come in 20 and 30mbs..as far as I know anyways.

the camera can holds 40odd jpeg in its buffer so I would say thats normal for a standard SDHC card....its really the RAW I need as its 15mb each picture over the 4mb of the jpeg.

I am thinking the 15mbs card should be ok, or do I pay a bit extra and proof myself for any future requirements...hmmm

Just from reading your last post, your RAW files are 15mb each and an UltraII is 15MBS so you'll get one RAW per second surely?

So if you get a 30MBS card, you'll get two per second, obviously this figure can also be limited to the camera, as to whether it can take that many per second

Buy the fastest you can get... with only 6 RAW files capable of being stored in the camera's memory-buffer, you'll need ultra-fast cards to get the buffer cleared ready for new shots to be taken.

it take 3.5 per second....BUT it will hold 6 raw picture in the memory of the buffer in the camera, so it doesnt transfer straight to the card, it will keep taking picture until the buffer is full, about 90mb (6 raw pictures)

with a standard card it will take 6 raw with a rate of 3.5p/s and transfer to the card about 5mbs, which will only empty the bank slowly.

So I needed a bigger card to empty the buffer faster, and didnt know if I could get away with 15mbs

would you suggest going for the 30mbs and full proofing my self over the 15mbs then?

I havent ventured in to the continues shooting much so any help welcome.

Card size is pretty irrelevant - that just governs the number of images it can hold - you need a faster card to empty the buffer quicker...

The new extreme pro is capable of 60MBS and I think they've just made a dual processing 90MBS card, so I can't imagine buffering being a problem with these cards

I use the Sandisk Extreme-Pro 16Gb cards which write at 90MB/s in my D3x and Extreme IV (45MB/s) cards in my D3...
To be honest the Extreme IV cards are fine for most applications in 'normal-sized' cameras...

I use the Extreme-Pro cards in the D3x as they're bigger and faster to cope with the huge RAW files generated by the 24Mpx sensor...Not cheap though...

Yes I meant 15 and 30 mb per second transfer rate, not size

Definately true!
