Sandisk extreme IV 8G - Not fast enough ?

[albert rudnicki]

I got two of those for my DSLR, thinking about RED.
I am testing them with built 15 (4k 24fps, and it says :
"The CF card has not been Speed Verified for use on this camera."

Am I doing something wrong? The Sandisk extreme IV 8G is 40 mb, it should work.

I just bought the exact same thing. I haven't had the chance to test it yet as I expect my camera by the end of the week. Let me know how things work out.

I've been given the same warning with my extreme 2.

Jamie the Sandisk Extreme II falls under 20mb transfer rate;
I think that you need at least 30mb sustained.

Albert, I gave it a shot on set, wondering what would happen. Seems RED took that into consideration and I got the same warning you did. Worth a shot, right?

Is it "locked" due not being recognized by the Red ?
Does Red need to "know" the brand in order to record.
It would be great to have simple speed test utility embedded in the next firmware.
