RAW 60FPS Recording Buffer Question

[Jason Montalvo]

Hi Everyone,

Was hoping to get some advice. I'm currently shooting on 5D3 with the latest build. For as long as I can remember once I attempt to shoot at 60fps and play with the resolution setting i'm unable to get a write speed above 60 MB per second. Is that normal? If so i'm cool with it. At 1920 X 1080 24fps i'm able to dip into the mid 90's write speed.

Thanks in advance for all the help.

Yes, that's normal.

The more frames per second have to be dumped simultaneously, the more the write speed drops.

My System:
Card Benchmark: 120 MB/s
1920 x 1080, 25fps: 90 MB/s
16xx x 560, 50fps: 70MB/s

I can't get a higher 50fps resolution to work beyond 1600 in 16:9. Recording more frames per second then 24/25/30 significantly seems to stress the dumping pipeline.
