Transcend 16gb SD card won't do video

Well, I purchased this card some time ago and seemed to have no issues. At the the time I was really pumped as I paid less for a 16gb card as I did for my Sandisk 8gb. I believe I even went as far as to recommend them to another member. Well, I'm no longer pleased as I went to record a video of my daughter today to find that it can't keep up with HD video. I would get about 8 seconds into the video and a little bar on my screen would fill then it would shut off. Swapped it out for the Sandisk and no issues. It's obviously a speed issue, which I don't understand as it's labeled as a class 10 same as my Sandisk. I've noticed no issues when taking pics only seems like its a video problem.

I have read that different manufacturers use different criteria for rating memory cards a certain Class. So ones Class 10 might really be anothers Class 6 with respect to actual data writing rates. Either way, theres a reasons the Sandisk was more expensive when you bought the Transcend, and now you know why.

Stick with Lexar or Sandisk (their best versions).

I had the same card for my mark III and had to change it for sandisk who was about $ 45 dollars more expensive. I lost pictures on the transcend card. Sandisk no problems.

What camera?

T3i

Which one of their SD cards was it? They have a couple different ones.

Not sure how to tell, and I'm at work so it's not in front of me, but it was a 16gb class 10. Blue card. Purchased from Amazon.

They have 3. Green label Class 4, Blue Label Class 6, Goldish label Class 10.

I just send a couple of the Class 10 to friend for use in her T3, so I will let her know
to give them a try when she gets them. She won't get them for a week or so.

So...buy a Sandisk card.

How much have you used this card before it started showing performance issues? Is it possible it is fragmented due to a lot of use, including a lot of images being deleted, esp if you were deleting them one at a time?

Have you tried to low-level format the card?

There are other less expensive, but just as reliable and reputable, manufacturers. Kingston and Lexar are every bit the equal of Sandisk in reliability and in meeting the stated performance specs of their memory cards. And, you have far less worry with getting counterfeit cards, too.

There is no benefit to a T3i to have a card any faster than Class 6, but it has to be a true class 6 and not a fudging manufacturer (not saying Transcend is...), not a fragmented Class 6 card, and not a counterfeit re-labeled Class 2 (or worse).

Obviously I won't buy another Transcend...this thread was more to warn anyone considering it and share my experience. I doubt its due to overuse since I've only had it for about 2 months with about 6-700 shots on it. And I did format the card.

I've been using the CF cards from Transcend for years. I have never lost a shot. That said in tens of thousands of captures, I have NEVER had any card fail me, from ANY vendor.

I dont think anyone here can provide proof that Sandisk or Lexar products are any more reliable than Transcend. I'd like to see it if they can.

Look, I'm no fan of Transcend. My only card failure was with Transcend, which leaves me suspicious. (I know, a sample of 1 is useless (you see a lot of Sandisk failures reported on this board, too), but I'm not eager to conduct a large test of Transcend after my very first Transcend card failed.) I have a brand new Transcend Class 6 8GB that I keep basically as a last resort card if I need it.

Even with this new & unused Transcend, I recently bought 2 Lexar 8GB cards and a Sandisk 8GB (but only because it was on sale and therefore competitively priced... JMO, but the "premium" pricing of Sandisk is pure brand-loyalty marketing). All my others are Kingstons. And the Kingston Class 6's work just fine for video on my T2i. I haven't tried the others with video yet. (I only fool around with video on the T2i; it is too much of a PITA to use routinely for video... JMO.)

I have no idea if Transcend fudges their performance class rating. After your experience, I may break out my Class 6 Transcend to run some tests, though.

But I do know that FAT32 is highly subject to file fragmentation, which can occur if you nearly fill the card and then selectively delete images, take more images, selectively delete, wash, rinse, repeat. Low level formatting will, in effect, defragment the card (along with map out bad sectors, if any).
