What are you using and what are the best cards for UHD recording with the GH4. I’m currently using 2-64GB San Disk Extreme Pro 95MB/s and need more Cards for a second GH4, I’ll appreciate your comments.
There is no such thing as bulletproof SD cards / storage drives / etc. Honestly, I think that any of the 'big brands' produce good quality SD cards right now. They are cheap to produce, so no need to skimp on certain parts or processes so they turn out less 'bullet proof'.
I think it is more about how you treat your SD cards than anything else. Don't touch the metal parts with your fingers. Don't bend them. Treat them like a 16 year old virgin and you will be fine.
For what it's worth, I'm using Transcend SD cards for 4.5 years now and never had a problem.
I recently bought the Transcend UHS-3 64 GB version of it and it performs well. Never lost anything yet. *Knocks on wood
"panasonic has said the older Extreme Pro 95MB/s can preform faster on UHS-1 ports than the UHS-II (U3) card. So don't waste you money on the Sandisk U3, and either get the Sandisk 95MB/s U1 or the Transcend U3."
That's possible: The UHS-II cards have a different interface (see the back of them) and when falling back to UHS-I it could well be slower. I vaguely recall someone testing it but I can't remember where I came across that.
