I use a transcend class 10 with my gh1. I am running the Blackout-Ipowell patch and i normally get about 50mbps so my card is fine, but i have read reviews about ones that are duds. For anyone that got a dud, how likely is is that you will get one?
I've had no problems with ADATA class 10 cards -- they seem to easily go over 4 gigs -- once recorded a 2 hour interview on one no problem. Transcend good too. Good prices at B&H.
I am considering the 32Gb for live event, where it will be an advantage not to have to change the card, but I actually dont know how much space the avchd codec is requiring, of cause that depends on what resolution and bitrate I choose. I will have a camera in a week, then --i can start to experiment :-)
+1 for Transcend class 10 cards. As with all storage, a card WILL fail at some point. The key is to have a backup solution in place and a good warranty. Transcend cards have a lifetime warranty.
I stick to 16gb cards for a few reasons: * Same price/gb as 32gb card (~$1.50/gb) (no savings going with the bigger card) * Multiple cards can be used in multiple cameras * If a card fails, I don't lose as much (only 16gb and not 32gb) and I still have another card to use * Limited recording time keeps me thinking about what I'm shooting, which results in less footage to sift through in post
I tried to find a SanDisk Extreme at the local Fry's Electronics, but they didn't stock them. So, I opted for a PNY Class 10 cheapy, which works great. And unlike the other cheap card I had lying around (a Kingston Class 10 Ultimate X 100x), the PNY actually works past the 4 GB limit and creates a new file. The Kingston Class 10 Ultimate X always crashes at the 4 GB limit.
