GH13 Sandisk SDHC confusion

I need to replace my Sandisk Extreme 30MB/s edition SDHC card after it was destroyed last weekend. Heartbreaking seeing it in pieces. Lasted me a long time. But oh well i'll just buy a direct replacement or so i thought. Apparently its been discontinued. But replaced by what? Cause it doesn't really seem clear, to me at least.

I've seen models called HD Video 20MB/s class 6, HD Video 30MB/s class 6, HD Video 20MB/s class 10, HD Video 30MB/s class 10. Some with the moniker SH-I some not. An entire new model called Extreme Pro 45MB/s. Model numbers that aren't even listed on Sandisk's website such as SDSDX-016G-X46

And the level of mislabeling by uk websites is incredible. For example Amazon UK: http://www.amazon.co.uk/SanDisk-Secure-Digital-Capacity-Extreme/dp/B0037FLUYU/ref=pd_cp_computers_2

Picture shows class 6 model, description says class 10. Emailed and have received no response from Amazon.

Could someone please point me in the right direction. Hell at this stage even recommend me a different brand that runs lpowell's 100Mbps Max Latitude Native 24/25p Patch.
 
They did change it up - I still have their "legacy" class 10 cards.

I don't believe the GH1 can take advantage of the speed increase of the 45 MB/s cards, because the new transfer speed came out after the camera itself did. You can use hem just fine, but you won't be able to access their full potential. You'll want a class 10 at minimum. I've had success with the HD Video 30 MB/s class 10.
 
Thank you sir. May have to buy the extreme pro 45MB/s just because it's the only Sandisk extreme SD card that's properly listed online.

Do you know if the extreme pro performs at the same level as the HD Video 30MB/s class 10 in the gh1 or is there a huge performance hit from not using it in a UHS-I compliant device
 
I haven't personally used the new 45MB/s cards, but I have heard that the GH1 will use the card to the camera's full potential. Meaning that the the card will behave just as a Class 10. Figuratively speaking say it's like a class 12, but the GH1's "engine" can't "go that fast" (access the faster speed-write, just Class 10). There shouldn't be a performance hit.

The different options seem to be listed clearly on B&H's site, at the least.

Cheers Neighborhood- really appreciate the advice.

I wish B&H operated over this side of the pond. Proper site with good prices. Too much to ask this side of the pond it seems.
 
the new UHS-I cards will operate at around 20mb/sec in the GH1....maybe even less. The 45mb/sec card utilizes the UHS-I technology, so it's no faster than a standard, any brand, class 10 card when used in the GH1.
don't buy into the "hype" that sandisk is putting out there. I tested two of the "new" HD video, UHS-I cards(32GB), on a san disk memory card reader, and USB 2.0, and they only operated at 20mb/sec. I also have an older Kingston Class 4 memory card, that operated at 19mb/sec......I sent the 2 Sandisk "new" cards back for a refund, and bought some cheaper Kingston class 10 cards, for my GH1.

Also, remember the difference between the small b(bit), and big B(byte), is a factor of 8. 8 bits to a Byte. So, divide 100mb/sec by 8, and you will have the maximum speed you need for your card.

UHS-I technology is geared towards newer model camera's, and, more importantly, USB 3.0. Sadly, neither the GH1 or 2 can take advantage of this new technology. So buy the cheap class 10 cards.
I still have an older sandisk Extreme 30mb/sec card, and it tested at 29mb/sec!!!! So, the difference between the "older" extreme cards, and the newer "HD Video" cards, is, IMHO, significant(29mb/sec Vs. 20mb/sec). For the record, the "new" cards tested at 20.31mb/sec read and 19.42mb/sec write. The old kingston class 4 tested at 19.80mb/sec read, and 12.89mb/sec write.
and the older "extreme" versions was 29.89mb/sec read, and 28.40mb/sec write.

I've tested the 100mb/sec patch, with my old Kingston class 4 without any crashes.
 
Thanks havasuphoto. i knew there was a difference between small b and big B, but didn't know the math. Must try to be more knowledgable about such things.

Reading about these new models has made me even more sad about my old (legacy) Sandisk SD card. I've looked at other brands such as Panasonic, and they've not muddied their products like Sandisk has (at least in the U.K). Panasonic still have their old Class 10 Gold SDHC cards, but they also have their new UHS-I cards as well. Kingston have done the same. Treated UHS-I as a complete sepearate product.

Sadly Sandisk haven't. Just lumped it with everything and continually changed product names. I see no reason why the 30MB/s edition had to be discontinued. Even on Sandisk's site it's still listed as their best product for the GH1 but i can't buy it anywhere without paying 3 times what i did back in 2010. Anyhoo rant over.

I managed to find the Extreme Pro 45MB/s 8gb for £17/$26 from a Sandisk approved dealer which isn't too bad i think. But I'm gonna pick up a Transcend and a Kingston class 10 and see if there is any difference over the coming months. At least i get to shoot this weekend.

ROFL!!!!
They lost me as a customer. I'll never buy another Sandisk card. I had ordered two of the older Extreme 30mb/sec from an online store. The pictures and the model number clearly showed it was the older model, in 32GB, which was exactly what I was looking for. Ordered them, and received the "HD Video" version. Tested them, my Class 4 equaled their speed, messaged the online retailer-I want to return-online retailer said you can't return memory cards. I explained to them that I ordered one part number, but they shipped me a different part number, refund received.
I bought the Kingston Class 10. Could have just as easily went with any other brand. But, I hate the "bait and switch" tactic that Sandisk pulled. IMHO, they were being less than honest with the consumer.

At least the other manufacturers were more honest about their cards speeds. And from what I have seen, Panasonic may be about the most honest when it comes to the new technology versus the old. Sadly, the Kingston cards where just a little cheaper than Panasonic, so I went with them.
I will still cherish and protect my "original" 16GB Extreme 30mb/sec cards. It's a speed demon.

From what I have seen, probably all online retailers are substituting the "new" card, and using a picture of the old style card. They are different part numbers-so if you find one, double check before ordering that they don't try and ship you the "new" ones-they're junk(waste of money). Also, the old cards have been discontinued, and are out of stock everywhere. :(....
 
I purchased a 16GB Sandisk Extreme Pro UHS1 SDHC card from Amazon for $52.99 w/free shipping last month and it runs much faster than my 16GB Sandisk Extreme 30mb/sec SDHC card when uploading to my 6-core PC using a Pretec USB 3.0 card reader in the USB 3.0 port on my Coolermaster HAF X case.

As well it should-UHS-I is optimized for USB 3.0. But, for the rest of us, still running ancient USB 2.0-it doesn't make any difference. :(....

sorry to hear about your mis-fortune. I bought my gh2 on a vacation last June to San Francisco, and bought my SanDisk sd cards from Samy's Camera in Los Angeles on the next stop of the same vacation. They had both extreme 30mb/s ($50) & extreme hd-video 30mb/s ($58). i asked the dude working the counter about the difference between the "hd-video" and non "hd-video" versions and he said it was just a marketing gimmick. it took me about 1/2 an hour to find any difference on google, the availability of information is that bad, not even the sandisk website had definative information. and even now there's no definative definition of what UHS-1 is. i guess it is a technology that allows faster transfer speeds, but in this case is irrelevant since they are both "rated" at the same speed. I ended up just choosing the cheaper version.

my laptop has usb 3.0 ports, i don't have a usb 3.0 card reader, but my laptop has an integrated sd card reader, so it doesn't really matter to me.
