Yeah I had the Panasonic 22mbps class 10 card and I sold it cause I thought it was the card...but even the faster card has that issue. I just gave up on using Ex-Tele ...
Will the new UHS-I cards even work in the GH2?... B and H is selling them now..I don't think Ill need one though, my 32gb San disc extreme pro 45mbps card seems Ok .I only get the card slow error when I use Ex-tele and only @720p60 it seems...so I don't think its the cards fault.
I'm going to buy a sdhc to better test the hack. Now i have a lexar class 4 and it doesn't go above the 40mbit. I'm going to buy a kingston class 10 do you think that it is good? Better a transcend? What bitrate they can hold? I'd like to buy a sdxc but they're fucking expensive
Any difference in speed between a Sandisk SHDC Extreme 8GB or 16GB? Shouldn't they have the same read/write speeds? I thought I've read there are some differences.
@daihard this was a couple of years ago, for a totally different device (i.e. one with microSD slot). Point was the thing was comfortably over-spec and knocking at the door of the next speed class. Take-home message being that the speed-class number is merely a minimum (and refers to read speed AFAIK).
Couldn't say about the lag, new gear still in the post :o) . SXDC is > 32GB rather than speed per se (officially supported on GH2 AFAICT, but their website is kinda vague), and yes, UHS-I is much faster read speed in supporting devices, but write performance is uncertain (early benchmarks showed relative slowness, the interesting question is whether it has improved)
@dkitsov h2testw is free & gives write speed while writing and average write speed when done, and writes / verifies pseudo-random data to be sure that it's stored and not overwritten as on some false-capacity knock-offs... no graphs or other niceness though.
I've invested in Transcend Class 10 16/32Gs mostly. The only time i've noticed a lag is when recording in 1080i on my GH2. Is this lag due to my card? Is there really a HUGE difference in these class 10s and SDXC or UHS-I??
FWIW I have a Sandisk microSD card at class 4 / 32GB, which has read & write speeds not quite up to, but very close to, the class 6 spec.
Apparently UHS-I does use extra pins in UHS devices - but what with write speed being generally much less than read speed for SD cards, I suspect that the limiting factor here is the flash memory itself, rather than the bus.
Of course, it's write speed, not read speed, that we're all interested in, right? ;o)
My Extreme HD video card has a 30MB/s rating on it. It cost less than my 45MB/s card with a UHS-1 marking on it. The both seem to have the same speed when read by USB 3 reader...
I tested an UHS-I Card (Sandisk extreme pro 45MB/s) in a non UHS compatible reader. It was strange. With little blocks it was as slower as a class 6 card, an with 1MB blocks it runs at 45MB/s.
In the GH2 the UHS-I has the same writing speed as a class 10 transcend card.
That's strange I thought the new UHS-1 standard actually had physical changes to the BUS. Does that mean 45MB/s isn't exceeding the throughput of the current interface? Maybe there are latency changes?
Would be interesting if you could test those 2 cards in a non UHS compatible reader, though the UHS card shouldn't work at all, right?
I just bought a new Lexar USB3 card reader, which I connect to a USB3 port, that sits on a card that is on a PCI-E bus and then I run an HDtach test (not sure how well it works with SD cards) on two different SD cards I have. 1st - SanDisk Extreme Pro UHS-1 45MB/s 16GB. It returned 45MB/s peak and the same sustained (as expected). Then I tested My SanDisk Extreme HD video class 10 30MB/s 16Gb. And guess what - 45MB/s peak, 45 MB/s sustained. I am speechless. PS. @Vitaliy_Kiselev Cannot attach a screenshot, get an "Internal Error could not move file" error
Don´t worry, you don´t have bought a chinese faked sdcard.
Germanys greatest electronic market sells exactly the same cards you showed on your picture with UHS-I written on it. On the card itself is written a litte 1, so I think that means UHS-I.
I had two 16 GB Sandisk Extreme Pro UHS I Cards, but they´re on the way back to vendor. I compared it to my Transcend class 6 card in Photo Raw burst mode and it was only a little faster when writing full buffer to card.
The other thing, I got writing errors (camera freezing) with my GH2 hacked in 720p60 Mode (30Mbit/s) and the Transcend class 6 went fine with the same settings.
No, 45€ (16GB) is too much money. I ordered two Transcend 32GB class 10 for the same money:-)
@last_SHIFT you wrote, you have one too, or did you mean something else? What does the package say in your case I'll check with H2test in a sec, DL'ed it but still have to find out, how this works... Don't think it's fake though, like last_SHIFT writes: "outperforms my old Transcend Class 10" - exactly like that for me... So when fake, at least it's a good fake, haha!
Mine are 16GB SanDisk Extreme Pro 45MB/sec UHS-1. Got them from B&H in new packaging. Tested them with ATTO Benchmark and they came in just a little bit faster than my Panasonic Class 10 cards - that I got direct from Panasonic.
Anyway since it's fast and not too expensive, maybe it's good to keep this in mind, if you want to buy a fast card (of course supposing, at least all cards of this model behave the same)
