Transcend has announced a couple of new SD cards. They're marketing the cards for use with the upcoming 4K camera's. At this point four cards have been announced, the prices are recommended retail prices:
- 32GB SDHC UHS-I U3X R:95MB/s W:80MB/s ($59)
- 64GB SDXC UHS-I U3X R:95MB/s W:80MB/s ($119)
- 64GB SDXC UHS-I U3 R:95MB/s W:60MB/s ($49)
- 128GB SDXC UHS-I U3 R:95MB/s W:60MB/s ($109)
Transcend recommend these cards for use with the Sony FDR-AX100, Panasonic Lumix DMC-GH4 and Canon EOS C500 in 4K modes.
If these cards can sustain the mentioned write-speeds, they should all be abled to record CinemaDNG files on the Blackmagic Design Pocket Cinema Camera (BMPCC) as well. However, we live in a real world and there's no such thing as a perfectly labelled card. So I personally think the U3-cards will be nice and reliable for recording ProRes on the BMPCC, and the U3X-cards will be good for CinemaDNG.
The cards will hit the shelves in Japan mid-April, the rest of the world will follow shortly after.
