I don't mean the Extreme Pro Version, i think you missunderstod!

.... Well my card runs way faster than that...so perhaps it fell on the floor at the Sandisk plant
Where is this "reputable" store?...

@havasuvideo - I have the 45mb Sandisk 32gig and it works awesome...You must have had a fake card or something lots of fake sandisks out there.

Test it with this;

And your card reader, and see how fast it really is.
45MB/sec is faster than most camera's can write. It's also faster than USB 2.0, I believe, can read/write.
I'm not saying these camera's are a problem-I'm saying they are misleading people into believing that they will get 30, or 45mb/sec read/write speeds. The truth is, you probably won't come near that.

Yes, they suck!!! Here is a comparison I did between the old Extreme III 30mb/sec cards, and the new UHS-I;
"I know some of you are trying to find the fastest memory cards for your Panasonic GH1s and 2's, as well as some other video camera's.

So, I recently placed an order from a major online retailer for 2 Sandisk 32GB SDHC Extreme III, 30MB/Sec memory cards.
The picture online showed the older style memory cards, without the HD Video, or UHS-I printed on the card, and that's what I wanted.

What I got, where the UHS-I, HD Video memory cards. I was pissed.
Now why??
Well, there is something that Sandisk probably does not want you to be aware of.
Their newer, Extreme SDHC UHS-I cards are slower, than the older Extreme III cards. And not by a little, but by a lot.

Keep in mind that UHS-I was developed to increase speed in devices capable of using this new feature/memory controller. I don't have one of those camera's. I also don't have USB 3.0-so this new feature is lost on me.

So, here's what I did; I decided to test the "new" cards, against an older, Sandisk 16GB Extreme III, 30MB/Sec card. And, just for fun, I also tested a much older Kingston 16GB Class 4 card.

The card reader was a newly bought Sandisk ImageMate(model 199A), which is optimized for reading Sandisk cards.
The computer is a PC running Vista 64.
I used Crystal Diskmark, as my bench test, running 5 tests, each with 100mb. Each card was formatted in the card reader with standard sectors in FAT32 before the test. I should also note, that my brand new card reader died, shortly after performing the tests-so it's being returned, as well as the "new" 32GB cards.

The results;
Sandisk 16GB Extreme III SDHC 30MB/sec card;

Sequential-Read=29.02MB/Sec Write=26.26MB/Sec

Sandisk 32GB Extreme SDHC UHS-I

Sequential-Read=20.89MB/Sec Write=19.41MB/Sec

Kingston 16GB Class 4 SDHC

Sequential-Read=20.90MB/Sec Write=12.28

And, just for fun, the read write speed of my SD800 Panasonic video camera, used as a memory card reader, with the 16GB ExtremeIII cards was; Read=16MB/Sec Write=14MB/sec.


So, why are the "new" memory cards not performing at 30MB/Second like the old cards?? Good question.
Why am I paying for the new UHS-I technology, when clearly, a Kingston Class 4 card is nearly the same speed, and I'm sure a Kingston Class 6 card would be identical.

Keep in mind that the class rating is a minimum, and it's normal for most cards to exceed this. Also keep in mind that USB2.0 is limited in it's speed as well.

I am returning the "new" Sandisk cards tomorrow, along with the broken memory card reader. I will probably purchase the cheapest class 10 cards I can find."

Other option is to get USB 3.0 reader.

Check any bought cards with this utility: http://mympx.org/Downloads/p13_sectionid/2/p13_fileid/13

It will show if the card is a fake (eg. lower size and just reprogrammed to report the larger size, meaning data gets corrupted as you fill it up), and also the average read/write times. It completely fills the card and then verifies the contents. I just had a fake 'Class 6 32GB' microSD card, that was actually a 1GB Class2 card. Ebay is flooded with these (domestically and overseas). It came with a bad quality SD adapter, the card had to be forced into it, and it still didn't work - and apparently the genuine Sandisks don't even ship with an adapter.

Bear in mind that the speeds may be limited by the card reader - I have a fast Sandisk reader that gives me the full speed of my 32GB 30MB/s Extremes, but many card readers crap out around 7MB/s.

I'm sure a lot of sellers are fully aware they're selling fakes - but the reprogramming is a nasty trick, many sellers put a few small files on the card and it seems to work, but they don't fill it up enough to discover it's been reprogrammed - and even if they do they just assume that particular card is bad, and sell it as 'faulty' on Ebay.

Small sale at B&H:

SanDisk 8GB Extreme SDHC Class 10 Memory Card - $25 ($20 for two or more)
http://www.bhphotovideo.com/c/product/580122-REG/SanDisk_SDSDX3_008G_A31_8GB_Extreme_SDHC_Memory.html

16GB ones are out of stock already :-(

Selling SDHC cards must be risky business :-)

Small note to readers of this topic.
>"I escalated the issue, and ebay gave me a full refund including shipping cost."
Do not do it, unless cruicial. Because 98-99% of sellers are good people and something can go wrong or you think that it went wrong. Communicate with seller and calm down.

Too late. I aleady sent.

Only after I opened up a case against the ebay seller, he accepted the full refund request. It took him 4 days to respond. He might be selling genuine Sandisk cards, but the slow response didn't give me good assurance. At least I'm not giving him any negative feedback since I can't really verify it.

What do you think about this card?

Hersteller: SanDisk

Modell: Secure Digital High Capacity 8 GB Extreme Pro 45MB/s UHS-1 Edition

this is the best?

I did check up on the german amazon page, and find both versions available, the prices are significantly different, and the technical specifications are confusing.... at the "HD video" marked card is specified at 20 MB/s even the printing says 30 MB/s.... yes confusing... too many employees being " overeducated-nonskilled"
and spending too much time on facebook and in other forums instead of caring about the work they get payed for.... ;-)
