SD Write Speed...

[thegisguy]

As I mentioned in another thread I just bought a Canon XS. It's my first SLR. I'm now looking to buy a big ol' SD card. My question is how fast do I really need? Is Class 6 (6MB a second) good enough, or should I go with a 15Mb/Sec or 30/MB a second card?

I think you mean the Digital Rebel EOS XSi. It has a fairly speedy response and sequencing capability of 3.5 fps. I would get the fastest SD or SDHC card (2 GB will suffice) I could afford.

I find today's best value is the SanDisk Extreme II SD 2 GB.

A SanDisk Extreme III 8GB card would do fine for you. I have two of them, but the older 20MB/s variety. They work plenty fine with my D90 at 4.5fps RAW, or 720p video.

Sorry should have added the Rebel to that model. It's the Canon Rebel XS. The Xsi is the next model up from mine. In any case, it looks like I was correct in my assumption that class 6 was not fast enough.

yes you want a fast card so the camera can write to them quickly, not to mention to be able to read from the flash quickly helps when you fill up that card.

Would this stuff be up to the job? I've had good luck with OCZ ram in the past. Any idea on the flash memory?

I don't know about SD, but I use an XTi with CF cards. I have a SanDisk Ultra II CF card (9MB/s write), but I also use a bunch of regular Sandisk CF cards. Only when I take bursts of 3 or more photos in RAW do I really run into problems. With casual shooting, even the slow cards work just fine.
