Just recently Samsung introduced an impressive 256GB microSD card:
“The EVO Plus 256GB raises the bar for capacity and performance of microSD cards thanks to Samsung’s advanced V-NAND technology, offering high read and write speeds of up to 95MB/s and 90MB/s, respectively. This level of performance will provide general consumers and professionals with superb user convenience for storing heavy-loaded, high-resolution photography and 4K video recording, as well as graphic intensive multimedia like virtual reality (VR) and gaming.”
Our reader Dixon tested the card on MFT cameras:
Just got a 256GB Samsung EVO+ (U3) microSD off ebay, so it may be an early sample. It works fine in still, but doesn’t work on any video mode in the GX-8 (firmware 2.1)–giving something like “Write Error. Check your memory card.” It work fine in all video modes in the GM-5, EM-5ii, and a Nikon D600. I am guessing it is a GX-8 firmware issue. Wondering if anyone else tried.
Why does that card matter for MFT folks? In the near future this kind of cards could be used by smaller cameras to save space. Or maybe you could have a dual miniSD card slot instead of one single SD slot.
