C300: C70 Buffer Overflow Issues

[Jon Roemer]

I haven't had a problem with these Angelbird 256GB V90 cards in my C70:

I haven't shot anything in slo-mo, but 4K 24p for long record times (over 1 hour nonstop) has so far been flawless.

Ditto here. I have three pairs of the Angelbird cards, 256G V90, and no issues so far. It does not seem to matter if Angelbird calls them "for Canon R6, Sony, or Panasonic". I have a pair of each and they work fine. Like Jaime, I have not done any slo-mo but all good on long record times.

Just to clarify, I am having great results with the ProGrade 256gb in 4K/24p/60p dual slot record mode. The issue is when shooting 4K 120fps.

Also, I put those same two cards back in the camera, unformatted, and tried to recreate the issue. I couldn't do it. Could this be a heat issue? Maybe with the cards themselves? Seems weird that it wouldn't happen again the next day. The file structures are in the exact same state...

Just want to chime in on something here, haven't really done enough testing to confirm or deny this as I just started getting Buffer Overflow a couple weeks ago...but....


Seems the only times I've gotten the error is when battery is under 10%. No errors with fully charged battery.

Not suggesting this is the problem or not, just something to look out for.

It could also be a heat issue. How much were you using the card before you had the issue? In my case, I had ran the camera in Dual Slot record mode for almost two hours. My battery was not low.

What cards were you using? Was it a fresh card?
