Chaps, I have my 64GB SanDisk Extreme Pro SDXC UHS-1 Card.

I've loaded my GH2 with Driftwood SeAQuake, and just for a test used two other cards. I'm using Kae's ColourDeathChart_Denser.png with on my monitor, using a Panasonic 14/2.5.

1. 16 GB Transcend SDHC Class 6: Fails just after 4 seconds
2. 8GB Transcend SDHC Class 10: Fails just after 2 seconds
3. 64GB SanDisk Extreme Pro SDXC UHS-1 (95 MB/s - 633x): No failure (ran the test for nearly 6 minutes)

The video won't play back on test number 3 though. Unfortunately, I've just discovered that my SD reader doesn't support SDXC, so I'm unable to look on the card to make sure nothing is corrupt. I'm ordering one, but it won't come until Monday.

I'm fairly positive the files will be OK though, and this card is capable of spanning 176 GOP1.

EDIT: Just found a local PC world that is open until 8pm, might nip out and get an SDXC reader now :-)

You can, but I had no idea where the cable was :-)

Anyway, I've been out to PC world, and I can confirm that the card spans with SeAQuake. I just browsed the MTS files and there are two with the same time/date stamp, and both play without any issues. Nice!

Any other tests to run? 80%?

Amazon.co.uk £166.69. Expensive, but not too much of a premium over 2 x Extreme III.

Great test results I cannot believe my eyes that the bloody thing will span. I was wondering if that card would do the Job but haven't got the cash to try it out.

Now we can record for a long as we want without it stopping, Wedding anyone?

Well done guys :-)

@Balazer maybe someone ate your crisps?

@balazer honestly I want's the 1:4! And now that it spans... ahhh... Can't wait to get mine in the mail! + New firmware in a few days! This Christmas is going to be sweet!

@simurg I'm 99% sure no.

I can confirm that I can playback files that don't span, including 80% (which only lasts 9 seconds). I've not tested again since, and I reformatted that card. I'll try and do spanning and playback later on if I get chance.

Does Quantum V2 24H span of the 64GB SDHC under high detail stress such as Stray's extreme dense chart?

@paglez, just tested Quantum v2 with new sandisk cards and confirm it does span. Filmed bushes of death, television, no problem.

MY QUESTION: can any one confirm that the new transcend cards also span?

Thank you JDN

@itimjim this one:

Thought I read reports that it spanned too... most of my interviews don't go over 2 hours so I don't want to shell out for another sandisk card but would like a backup for long interviews (and a cheaper one at that).

Yes. It spans.
