Watch out! May be inferior product. I got a speed grade class 2 (slow) even though package says class 6 (fast).

I bought two of these A-DATA 16GB Turbo SDHC "Class 6" memory cards for my Canon Vixia HF-100 camcorder. I put them in (one at a time -duh) and the HF-100 reports one card as CLASS 6 -Yeah!, but the other as CLASS 2 -Boo!

A real disappointment for me as the HF-100 needs class 4 or better to record in FXP mode. I get a nasty popup on the view finder "Class 2 memory. Cannot record in FXP mode". Bummer!

I can't help but throw in the specutation on how they are able to get such a great cost and beat the competition: buy reducing quality, accepting more marginal parts in their test programs, and use tier II foundaries. There are lots of ways to cut cost in production, but in the end it comes to quality. I am certain that every part that leaves the factory is tested, that is normally how semiconductors are fabricated, so why then did the part I receive not meet spec? Surely it must be because the parts are marginal and they are not testing all corner cases. Certainly companies like SanDisk who have a much broader business at risk would not risk lowering quality standards to achieve short profit gains.

In conclusion, if you want a 16GB part and are willing to take some risk on performance (speed/integrity) this might be the part for you.

If you absolutely need Class 6, and cannot be bothered to ship things back when they don't work - like me, or are very concerned about data integrity, you may want to go with a more well known supplier who has an established qualty record and name to uphold.

I should rate this product a 1 because of the performance issues, but in the end I was able to use the slower speed part in my Casio Exilim EX-Z1050 camera and it works ok there (no speed grade requirement on that camera). So I manage to salvage a bad situation.

Now I am going to order another 16GB card. This time I will try Transcend. Ha! No they are not SanDisk! But the HF-100 recognized a Transcend 8GB card I had laying around as a class 6, so maybe the 16GB will be ok too. I know I am taking some risk with Transcend too, but I just can't bring myself to fork out the dough for SanDisk. After I loose all my vacation videos and pics I may reconsider my penny pinching tactics though -we'll see.

Update: the two Transcend 16GB parts were recognized my the HF-100 just fine

It really takes a lot to impress me but this little card really does the job. I bought it to use with my new Creative Zen player and it is great. Fast access and readily accepted by both my player and card reader. Not a problem to be had and yes it is value for the money.

Most likely will buy a couple more in the near future

I was a little nervous buying an unfamiliar brand of SD card (this one is manufactured in Taiwan). But the results were good! My new camcorder (Canon VIXIA HF100 Flash Memory High Definition Camcorder with 12x Optical Image Stabilized Zoom) requires a class 4 SDHC card or higher (this card is rated as class 6) and it works great. No need to spend more...

At this rock bottom price, the only issue is, does it work? Yes it does (with my Cowon D2 2gb). What to do with this ridiculous amount of flash storage? Not sure (unless some fair use exceptions are put in the dcma - now, I'd vote for anybody who'd promise THAT!).

I use it in my Panasonic HDC-SD5. Filled it up and cleared it several times and it works great. All my recording is HD and large files. So far so good!!! I also never take it out of the camcorder. I transfer all my stuff through USB to my mac.
