Hi everybody,

Just got the Sandisk Extreme pro, so I run some test compare to the 20$ cheaper toshiba.
The result for ml raw recording test :

Sandisk Extremepro  1920p 24 fps = ok
Sandisk Extremepro  1920p 30 fps = ok

Toshiba Exceria pro  1920p 24 fps = ok
Toshiba Exceria pro   1920p 30 fps = drop frame and stop

For the BlackMagic diskspeed test I use Lexar usb3 reader

Toshiba Exceria pro 32g    Write  126 mb/s  Read  153mb/s
Sandisk Extremepro 32g   Write  138 mb/s  Read  151mb/s
Sandisk Extreme 16g        Write  75 mb/s  Read  95mb/s

I don't really need the 30 fps, I was happy with 1920 24p but I found drop frames sometime 1/30 ( specially on wide zoom 360Pan and when card get full).
That why I buy the Sandisk with hope that the 12mb faster writting speed will give me stability on the footage.

I don't activate drop frame , so the record should stop .
But the record don't stop and I still get drop frames with out any warning (maybe the buffer turn yellow or red)
The issue is I can hardly check if the footage have drop frames in the mlv viewer , lot of time I discover it on my computer.
Someone know how to better detect those Drop Frames ?


I'm gonna test if this San disk can give me peace .
