Best memory card for rebel T3i

I got a 32GB SanDisk Extreme card for my T3i and it works great. Burst shot in JPG format are pretty quick however taking RAW images tends to be a little on the slow side. Taking videos with this card is very smooth though. Best bang for the buck IMO

do cameras have a limit on how big of a card they can accept? no reason a 32GB Sandisk SDHC would not work on a T3i?

The T3i supports SD, SDHC and SDXC specifications. The largest SDHC card is 32GB, but the largest SDXC card is (theoretically) 2TB, so you should be covered for awhile!

The T3i supports SDXC cards, which means the theoretical upper limit for card size is 2 TB. Cameras that support SDHC cards as their high end top out at 32 GB, while cameras that require SD cards have 2 GB max. capacity.

thanks for all responses. +rep to you all!

I have the T3i with a PNY 8GB Class 10 SDHC professional memory card. My problem is that the video and sound is jumpy when I download it. I've downloaded to my laptop and PC is it he card or the computer equipment with same results. Please help

had sandisk 16gb with 30.gave them to my wife after I got 3, 16gb with 45 for less money. the 45 seems to upload faster to my pc than my old 30's

The PNY "Class 10" cards I could find online seem to be rated at "up to 20MB/s". In general, for video, I like to have cards that are rated a bit faster, say 45MB/s like the Sandisk Extreme Class 10 UHS-1.

Have you tried re-formatting the card? How does it play on the camera itself? Is it just as jumpy as after you download the file to a PC?

Otherwise I dunno. Try another, faster, card anyway: they are relatively cheap, IMHO, compared to the camera that is capturing the nice video.

Pardon me, but this advice is off track.

First of all, if the sound/video is jumpy, that has nothing to do with card speed. That has to do with your playback. Presumably, you are copying the video files to your computer for playback. What program are you using to play the video? Are your computers up to the task of dealing with HD video files?

If it was the card speed, your camera would have halted recording. It would not record "jumpy" video.

Finally, there is a persistent notion floating around this forum that video is somehow very demanding of card speed. It isn't. Your T3i's HD video stream is only 5.5MB/s. That is class 6. If your card is performing at 5.5MB/s or faster, that is all you need for your camera's HD video. Faster than that buys you nothing. There is no reason to pay for anything faster for recording video. Of course, this is assuming that the card is not counterfeit or otherwise not performing up to its labeled speed.

Faster cards will upload the files to your computer in less time, however, assuming your card reader is also capable of the faster speed.

Well, that's why I asked whether the video played smoothly in-camera. Because if it does, then it is indeed his computer's playback system messing up. But if it is choppy in-camera, then it got recorded that way...which means it is the card (or the camera it self, I suppose).

There are plenty of devices out there that will record choppy video with marginally-performing cards, and I assume the T3i may behave that way. If it truly is impossible then so-be-it, but I wouldn't be surprised if it was possible.

Rob Galbraith's tests show that cards that are rated at the same speed will perform quite differently, and none of them live up to the advertised data rates, so perhaps the poster's PNY is not living up to its rating.

Again, the Canon DSLRs do not record "choppy" video. They initially save the video bit stream to their internal buffer memory, and if the card cannot keep up with emptying the buffer, it fills up, and video recording merely stops. It then has to be manually restarted. So, no "choppy" video. Just a very short clip (a couple of seconds sometimes) before it just stops.

This is my first post!
So i'm a little confused. I have a PNY Class 10 Micro SDHC 16gb card and it also stops recording within seconds. Does this mean that the speed is not 10MB/s? Shinksma said that he prefers a minimum of 45MB/s write speed for video but others say you just need a minimum of a Class 6, 6MB/s card and that the results should be virtually the same. Can someone help clarify this?
I'm interested in purchasing the SanDisk Ultra Class 10 Series cards, will these work for HD video? They are rated 30MB/s. Thanks for the help!

Your manual can clarify it. Canon recommends class 6 for video. See your manual.

Your video bit stream is 5.5MB/sec, which is well within the specs of a class 6 card. Anything class 6 or above will work fine (unless the manufacturer is "cheating" on the class marking).

I have a Sandisk class 10 16 and 32gb cards. Works fine on video.

I got tthis one 28$ last month. I love it.

Sony 32GB SDHC Class 10 UHS-1 (SF32UX/TQ) 94 mb/s

So is there no weight to the higher Write Speed argument then? Just as long as specifications are met, 10MB/S vs. 90MB/S is going to give same quality and performance? Thanks so far.
