With the upcoming 400Mbps firmware update for the Panasonic GH5, which will finally bring some “natively editable” 4K 10bit Intra codecs for those of us struggling with the IPB codecs at the moment, one has to think about the possibility of new SD cards capable of dealing with the new data throughput. Sure, 400Mbps is technically around 50MB per second, and currently any cards capable of such write speeds (or within the reasonable vicinity) could potential do the job, from what I was told by Panasonic reps at BVE 2017 in London is “to get some really fast cards”.
Much tests are due to be made on various SD cards currently available both in the UHS-I and UHS-II standards such as the popular Sandisk Extreme Pro 95MBps, and the Lexar 64 GB UHS-II 1000x (150 MB/s), both of which currently work fine in all codecs and resolutions in firmware 1.1 on the GH5, at least in my tests. However, like many of you, I am keeping my eyes peeled for new cards on the horizon.
Recently I spotted an announcement for some new cards from ADATA Technologies. This is a company, I wasn’t really familiar with, but it seems they do make DRAM modules for PCs, SSDs, and external drives in addition to USB drives. And now, they appear to have some really fast new UHS-II cards, that I may be giving a try soon.
Their new Premier ONE SDXC UHS-II memory cards meet the latest standards, providing ultra-fast read up to 290MB per second (and write up to 260 MB/s on the 64 and 128GB versions), which is about three times faster compared to UHS-I SD cards.
ADATA Technologies Premier ONE SDXC UHS-II memory cards also support highest-level V90 specs, meaning they can record up to 90MB of video per second. According to the manufacturer “this is more than enough for Ultra HD 4K, 8K, 3D, VR content, and 360-degree capture, all of which are especially suitable for professional photographers”.
