Summary: Can only use 1GB of 8GB card!?!
Comment: This card would not work to capacity in my Panasonic HD camcorder, or any other camcorder that requires sdhc. I would get about 1 GB of video on the card and then I would get errors on 3 different HD camcorders! I sent it in for warranty and magically, ADATA lost it. They make horrible products and then their service BLOWS! Don't buy anything from these guys!

Summary: Speed grade may not be correct
Comment: 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!
Being in the electronics engineering field I can't help but throw in this specutation on why: I suspect that A-DATA is able to get the cost of the memory lower than competition by increasing their yield at the silicon wafer fab. How do they do that? Easy, by loosening their test requirements and accepting more marginal parts. Marginally processed parts or marginal masks, old masks, accepting marginal parts at the the very edge of the wafer, using Tier I foundries, lots of ways to cut corners and cost -this is all pure speculation on my part, but when one recieves a very low cost, poor quality part from a relatively small player, one must ask how they got the price so low. Certainly companies like SanDisk who have a much broader business at risk would not risk lowering quality standards to achieve short term gain of higher profit at the expense of quality. But you will pay more for that assurance.
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.

Summary: Works great in HP iPAQ 111
Comment: I bought this for my HP iPAQ 111 and it works just fine. I down loaded several GB of power point, word, and PDF files and it all works well.

Summary: You might want to pay more for a different brand.
Comment: Purchased 2 of these for my Canon AVCHD Vixia HF100. One of the cards works fine (so far) but the other doesn't work at all with this camcorder. I get an error message on the LCD camcorder screen, "Check Card!" It's a shame I was in the middle of my (Alaska) vacation when this occurred. The price is right but there's a bit of a gamble here.

Summary: JamStreet Productions
Comment: I received my A-DATA 16 GB SDHC card, and it works excellent with my Panasonic HDC-SD9 High Definition Camcorder. At the highest quality, I can get a little over 2 hours of High Definition video. The recording and playback works fine, and it does what it's supposed to do, for a very good price. I didn't format it, as it's already formatted, so I won't take a chance and possibly mess it up, but you never know, it might still work if I were to format it. But I won't, I have to do a Wedding soon, so I will wait till after the Wedding is done.
It's worth getting.
Derek.
