Re: microSDHC UHS-I cards
In reply to Scottelly, Apr 17, 2014

I sure hope it can, but such information is difficult to come by. I'd like to see a test which shows the difference between the V2 and V3 write speeds (and buffer sizes). That sort of stuff is REALLY important with cameras that can shoot at such fast frame rates.

According to Imaging-Resource the buffer clearing time for the V2 is pretty fast - 22 seconds for 40 raw shots. Presumably the V3 is the same, but it might be faster, since the design is significantly newer.


I guess you are right here. Since there are already micro-SD cards that can receive data at 50 MB/s, the buffer clearing times will be limited more by the camera than the memory cards. I think 50 MB/s will be the maximum the camera will be able to write at, because I believe that is the UHS-1 standard's maximum write speed. UHS104 (faster than normal UHS-1, but not quite UHS-2 speed) would be nice, but I don't think this camera would have that. Wouldn't it be awesome if the V3 had a UHS-2 slot? Do they even make UHS-2 micro-SD cards yet? (I know Toshiba is making those disgustingly fast UHS-2 Exceria Pro SD cards.)
