ARRI Forum

Currently we are shooting with the Alexa mini camera.

I've done a lot of research, but I can't come to a conclusion, so I'm posting on the forum.

As the title suggests, it is a problem with the memory card and the camera.

We use 4 memory cards, all of which are 256GB CFast2.0 cards from Sandisk.

Often the camera will guide you through these phrases.

'Recording stopped : Write rate of recording card decreased.'

So the first time we updated the firmware to the latest version, but the same thing happened.

Afterwards we bought new memory and tried it, but the same thing happened.
(The capacity is the same.)


Last time I tried changing different camera bodies, same thing happened.
(The model is equally mini.)

I am posting this to find out the cause, so I need your advice.

thank you.

I had several issues with Lexar cards and then san disk cards also started giving one error or the other. Tried forums too but not much info available. I tried to replicate some problems , mine was that card worked in mini but many times didnt showed up on reader, the issue particularly came with Open Gate raw recordings. This particular error of writing stopped data rate decreased was in one lexar card. I now replaced them with angelbird arri editon. I suggest you list the card name as their are lot of version of san disk 256 and its firmware so someone expert can help you further.
