I purchased a few of these elsewhere, but B&H now has the Sandisk Extreme UHS-I Speed Class 3 SDHC Memory Card (Class 10) 65 MB/s cards available now. These are not fast enough for the BlackMagic Pocket Cinema RAW, but a great option for your GH4 4K or 1080p 200MB/s files if you want to stick with name brand.

I'm pretty sure I've had the errors when shooting MOV
FHD 200M - ALL-I /60p
FHD 100M / 60p
and I'm pretty sure even at
FHD 200M - ALL-I /30p
FHD 100M / 30p
yet i've shot
4k 100M / 30p without issue. very strange.
I haven't tested all the different settings, just noticed it stops on these.

cool. i'll try one of these. this is the transcend I have, works for everything fine but stops really quick on the bigger files.

Post author@Southerndude - Thanks for the tip! I don't shoot with much Sony these days, but maybe i'll test the A7s for kicks.

Post author@aaron - I have been using this with my (3) GH4 cameras without issues. Which transcend do you have exactly?
aaron
I have a 64gb Transcend SDXC I card that says it's class 10 / 3 and 60mb/s and on my GH4 it seems to write at 4k fine but stops a lot when set to 1080 200mbs, and sometimes even at 100mb.
but these should work fine? On the high end?

Emm: Just know that these Memory cards will not work with the Sony XAVC-S Codec, Sony throws and error message. I have an RX-10 which Sony just updated to Firmware 2.0, they added the XAVC-S codec to this firmware update, the error message says "This codec only works with SDXC cards.
Great little Camera by the way! Loving the small kit!
