Question: A7RV using Kingston 256GB Canvas vs SanDisk 256GB Extreme PRO UHS-II SDXC

If you are concerned about your image security or possible memory card failure, do you record simultaneously to both memory card slots? This assumes using one camera and not a question about brand of memory card.

• no indications during shooting, but various images were later found to be corrupted — frustration, disappointment, anger…
• at one point, the writing to card took a long time, which could only be resolved by turning the camera off and on again — i was lucky enough to be able to replace the card on the spot — delay and momentary frustration

I always record Raw + JPEG (highest quality) simultaneously to both memory cards.

(I don’t do video.)

Yes. A few years ago, on a camera with a single memory card slot, two separate situations:

• no indications during shooting, but various images were later found to be corrupted — frustration, disappointment, anger…
• at one point, the writing to card took a long time, which could only be resolved by turning the camera off and on again — i was lucky enough to be able to replace the card on the spot — delay and momentary frustration

Side note: I have learned not to “curate” images in the field — specifically, never delete.

Also: I never re-use old cards when buying a new camera.

Also: I always format the cards in camera. I never treat the cards as long-term storage for accumulating images across multiple sessions — I always re-format the cards in camera before a new session.

As you suggested, no mentions of brands.

YMMV

No. Never done that. What is important in order to avoid card corruption is to only use original OEM batteries with data and temperature terminals

Between those two, I personally would get the SanDisk Extreme Pro.

(I’ve been using SanDisk Expreme Pro for all my cameras. Lately, I also use Sony Tough G. If I spent $4000+ on a camera, I wouldn’t be cheap on memory cards and spare batteries.)

I feel the same way, have used the SanDisk for years and never had an issue so I’ll be getting a few for my a7rv also.

I switched away from sandisk when they refused to provide video specifications for sustained rate which for me was quite dodgey

Never used them since. I think Sandisk was actually the only brand where I had a memory device completely corrupted and refusing to mount at all which ended up in the bin

Interesting, in well over 10 years of shooting all around the world I’ve never had one fail, but I’m certainly not against switching to something more durable when my a7rv arrives.
