Yeah no worries, just thought it was worse asking. Sometimes people overlook the simple stuff but it sounds like your on to it. I too had a bit of trouble with the Vanilla hack, I've been having more luck with [url=http://www.personal-view.com/talks/discussion/2123/gh2-cake-v2.1-reliability-and-spanning-in-720p-hbr-24p-and-vmm-at-2-2.5x-stock-bit-rates/p1]Cake[/url] 2.1 and 2.2 by balazer, but I'm sticking with 24fps. Best of luck.

Could be a fake card, or just a dud. Any chance you can swap it?

[b]niphot:[/b] One other suggestion, try doing a low level format (Full Erase or Full Overwrite) with the SDFormatter tool from the SD Association. https://www.sdcard.org/downloads/formatter_3/ You may then need to perform a quick format in camera, but I have read reports of this helping cards in certain situations.

[b]niphot:[/b] I would be most concerned about your 16gb 95mb/s card. Was it from a reputable seller? Or maybe just a production fault? The reason I say this, last night I flashed my cam to Cake 2.1 to test with my cheap SanDisk Ultra Class6 30mb/s cards. With the 24p1080 24H setting (70mb/s in PTool from memory) it could only capture about 20sec at 1600ISO on a death chart before filling the buffers and locking up. But in 24p1080 24L mode (50mb/s) it was stable at 1600ISO for over 10mins (the filesize was about 3.5gb, need to let it run a few mins more to check for spanning). Your card should [i]easily[/i] be able to capture 70mb/s with Cake 2.1, I'm sure the guys on Personal View are capturing much higher bitrates with the smaller sized cards even if they can't span. Something seems wrong with yours. Does anyone else have an 8-16-32gb 95mb/s card to confirm? Also, try StreamParser to analyse your files, you can spit out nice summaries like this from my 24p2080 24L test above: [img]http://i39.tinypic.com/2ps366u.png[/img]

[b]smon222/dtr:[/b] If your desktop/USB card reader has UHS-1 then surely any benchmarks are pointless? OK if you want to compare cards against each other, but no indication of how they should or will perform in the GH2 as the relationship without UHS-1 may not be the same. Feel free to correct me if I am wrong. Having said that, I used an app called HD_Speed: http://www.steelbytes.com/?mid=20 Instructions posted here, along with data collected from back in the GH13 days to present: http://www.dvxuser.com/V6/showthread.php?217260-SD-SDHC-Card-Write-Speed-Tests [b]niphot:[/b] your experience with the Extreme Pro 95mb/s card sounds ominous. I knew they had problems spanning with the ultra HBR hacks but I thought they where OK otherwise. Just a simple thing to check, did you format it in the camera? This thread has much info about the 95mb/s cards, even though they concentrate on the 64gb versions which seems to be the proven (though insanely expensive) winner: http://www.personal-view.com/talks/discussion/1491/95mbs-sandisk-extreme-pro-spanning-reports-64gig-sdxc#Item_141 [b]jguk:[/b] are you sure about that? I know it won't span with Ultra HBR hacks, but surely it's OK to use otherwise, they're still the highest rated card SanDisk has to offer. niphot's experience doesn't sound good. Maybe I need to go through the above thread again. I'm still in negotiations to return my Ultra Class6 30mb/s cards. Was shooting with one on the weekend and RAW+Jpeg caused me to miss quite a few shots, the camera couldn't clear the buffers quick enough. Ended up switching to Jpeg only.

[b]dtr:[/b] any updates with the real world testing of your 45mb/s card? Everything I'm reading sounds pretty grim for this model. [b]smon222:[/b] regarding your 45mb/s SDSDRX3-032G-A21 These serial numbers are pretty much useless when trying to differentiate the cards. According to SanDisk support: SDSRDX3, SDSDX3 and SDSDX all specify the Sandisk Extreme SDHC card, 032G is the capacity obviously, and the last A31/A21/X46 identify the different manufacturing sites. The same serial number is used even when the models are refreshed with different internals and different branding and ratings. The SanDisk website is full of mixed information and not updated properly. My understanding is that the newer cards are rated higher if used on a device with UHS-1 bus which our GH2's do not have. If you divide the new ratings by 1/3 you get closer to their true capability on a non-UHS-1 device which coincidently match up to the old speed ratings. My guess, same chips, new ratings and stickers. Ignore all the Class 4/6/10 stuff for a moment and consider: Extreme HD Video 30mb/s -> Extreme Pro 95mb/s Ultra 15mb/s -> Extreme 45mb/s Standard 10mb/s -> Ultra 30mb/s So our two best options: 1. source old stock of the Extreme or Extreme HD Video Class 10 30mb/s as these seem to be proven cards which work with 44mb/s Vanilla. 2. pay big bucks for the new Extreme Pro Class 10 95mb/s cards, 64gb if you need high bitrate spanning or the 8/16/32gb ones if you're sticking to 44mb/s Vanilla. Unfortunately, although there is pages and pages and pages of anecdotal reports on various forums, the information gets outdated so fast and SanDisk doesn't help matters with their crap naming scheme. So take this with a grain of salt and feel free to refute and correct my assertions.

Big discussion here about the 45mb/s cards: [url=http://www.personal-view.com/talks/discussion/90/sandisk-extreme-sdhc-cards/p5]http://www.personal-view.com/talks/discussion/90/sandisk-extreme-sdhc-cards/p5[/url] Seems to be at least 2 different versions of them marketed. Extreme Pro & Extreme HD Video, both 45mb/s rated. Some are using a UHS-1 mode to get the higher rating which the GH2 does not support (my basic understanding is that it's like a dual bus for 2x speed, so GH2 can only do half the rating), this also seems to be the case with my Ultra 30mb/s, UHS-1 mode whereas the older Ultra was 15mb/s. Confusing much?

Bugger, I just tried 720p60 mode with the 44mbit Vanilla hack & it almost instantly locked up & displayed this error: "MOTION RECORDING WAS CANCELLED DUE TO THE LIMITATION OF THE WRITING SPEED OF THE CARD". Camera then became unresponsive to all/any button presses, couldn't even switch it off, had to eject the battery. So it looks like I must now beg & grovel for a refund. Purchased via a small Aussie based web store so I don't know if I'll have as much luck as if I got them from a brick & mortar. Checked packaging and the front says "UP TO 30MB/s*" and the fine print: "* Up to 30MB/s transfer speed; write speed lower. Based on SanDisk internal testing: performance may be lower depending upon host device."

To answer my own question I bought 2x of the new Ultra 32gb class 6 cards rated at 30mb/s and initial testing with GH2 using EOSHD Vanilla 44mb/s hack has been fine. I've only tried some short (1-3min) low light clips using 12800 iso b/w mode, yet to test lengthy clips requiring spanning. Should I try filming the "death charts" to test the card more thoroughly? A bit new to this.

As well as the Extreme Pro being upped to 95mb/s, the Class 6 Ultra line has been upped from 15 & 20mb/s to 30mb/s, anyone know if they're as good as the old 30mb/s Extreme line?
