I need a no-nonsense memory card for my T3i and I can't get a straight answer..
I bought one of those PNY Professional 32GB SDHC memory cards because it said CLASS 10 and I naturally assumed it would be perfect for my T3i.
Buffer overflows. Buffer overflows everywhere during HD recording.
What cards work best for you guys? I need to return this to Amazon for an exchange. x_x
Also, the differences among cards of the same class is ridiculous...
Sandisk extreme 2 or 3, class 10. I use those with my hacked GH13, and you really can't go wrong. I know quite a few people recommend the sandisk on here.
What Amazon dealer did you buy that from? You sure you got a "real" Sandisk, and not a fake?
"It is dark the other side. Very dark!" - "Oh, shut up and eat your toast!"
Yeah watch out for the fakes. If you have a genuine Sandisk Extreme (buy it from Jessops or Best Buy or some other high-street retailer) then you will have no problems with buffer overflows. I have five sandisk 8gig and 16gig cards and I have never had a buffer overflow.
It sounds suspiciously like your card is a fake. So many of these ebay and marketplace cards are nicely packaged but they turn out to be lower speed cards stickered up as high speed.
Absolutely. I have some fakes but they are only for stills.Originally Posted by AJUK
I use a SanDisk Extreme as my primary card and a Lexar Professional as a backup on my T3i. I've only had the recording stop once on the Lexar, but otherwise it's been great. The SanDisk has never failed me.
I've been using the Transcend 32GB SDHC Cards ($47.96 USD) for a several months with the T3i, just make sure you format them before shooting anything inportant.
I recently made the switch to smaller sized Lexar 16GB Professional 133x SDHC Memory Cards (Pack of Two for $59.99 USD) which IMO are just as or even more professional than Sandisk.
I switched to these smaller 16GB cards for 3 reasons, the first was the amazing robust quality and minimum write speeds, second being the awesome price point the REPUTABLE B&H dealer has them on for right now (NEVER Buy from Amazon or eBay because half of them are clever fakes!), and finally I had recently experienced a write error on one of my Transcends, which cost me 1 1/2 hours of valuable event footage which I could not re-shoot, because I failed to format the card before shooting. Your workflow changes a bit because you are using more cards, but it is changed out in mere seconds and when something goes wrong, you only risk losing about 45 minutes of footage. I used to preach against having to use small 16GB cards, but now, I have to eat my words.
Have a look HERE for the exact workflow I have adapted to using on all of my shoots. You will never overwrite exposed digital negative film with these methods, and the backup to a computer and 2 external drives, one placed in a vault is the best method for anything paid.

Good link there HD, interesting bit of info even if it's mostly related to the Canon cameras.
I've also used Transcend 16 GB Class 6 cards, and as already said, if they are freshly formatted, I've had no problems. Delete a lot of stills and/or videos, and these cards will get buffer overruns.
I've got 18 of them, for the same price I'd have to pay for just three or so SanDisk 32 GB Class 10 cards...
Since I'm shooting documentaries, where I can always re-shoot a scene if there's a problem, I dare use such "borderline" cards. So, I'm just telling, not recommending...
I have two genuine 16GB Sandisk class 10 cards that work flawlessly... I have one Verbatim class 6 (advertised) card that works, but triggers 3-5 red bars - my HF S10 can use it but recognizes it as class 4.... It works well on the HF S10 though.
Yeah B&H has really embraced the HDSLR niche market, wisely so, because it is so lucrative... they have a whole new section of (pricey) gear now too:

The other HDSLR Educational Series videos (though Canon focused) are rather informative, and Shane Hurlbut, ASC although full of himself, is rather entertaining.
This is the straightest answer you're going to get. Canon service techs often advise folks having this kind of problem that the Canon cameras can be "brand picky". They advise the camera owner to try SanDisk Class (6) or faster and when they do the problem goes away.I bought one of those PNY Professional 32GB SDHC memory cards because it said CLASS 10 and I naturally assumed it would be perfect for my T3i.
Buffer overflows. Buffer overflows everywhere during HD recording.
The buffer overrun happens because the card cannot keep up with the camera, regardless of specifications listed on the card or regardless of speed rating printed on the card, this happens.
PNY used to be one of the brands I used with my Canon HF100's (which require Class (4) cards) and they worked fine, the few I have left still do IN THOSE CAMCORDERS.
SanDisk Extreme Class (6) {but the supply of these is "drying up"}, SanDisk Class (10), and lately the latest SanDisk Extreme Pro 45MB/s cards. I get the latter from B&H for $69 for 16GB and have 3 of them in the media case packed with my 60D
http://www.bhphotovideo.com/c/produc..._Pro_SDHC.html
The media case for my T3i has a variety of Class (6) both 20MB/s and 30MB/s (I think this version evolved into the Class (10) and a couple of Class (10)...All SanDisk.
Ridiculous but still there and something to beware of. Part of it may be due to counterfeit and part just due to lack of the same QC the top companies have.
OK...Here is the ultimate question. How happy are you going to be, if after hours expended on a shoot, you get back to your computer and find out some of what you shot is either not there or not usable due to some media problem? That's the bottom line. I'm retired, I've "sweated out" my share of weddings and important events, waiting for the film to get back from the lab. What I do now is mostly on a personal level, but like in my professional days, the product I get out of the camera is extremely important to me.
I used to use fresh film (stored under refrigeration), my processing accounts were with the best color labs around the nation, and I NEVER considered a "bargain" material or service.
Same now. I'll pay the price for SanDisk, grit my teeth, and move on.
By the way, that SanDisk Extreme Pro 45MB/s SDHC card is the most solid built physically I've seen yet.

I love Transcend cards. Never had a single problem with them. You should buy them.
