For a long while now, we’ve been using the Sony a6300 as a second camera/frugal 4k camera. The quality is superb and really, we could not be happier. Well, that’s a lie, we could be happier if the darn thing did not overheat after 15 minutes of use. OK, skipping to another story: Over the last few weeks, we’ve moved from our old fleet of Sandisk Extreme Pro cards to Prograde V60 cards.

We noticed that after the move to the UHS-II cards, the a6300 is no longer overheating. At least in out controlled studio environment. For testing, we turned the AC off (as you can probably tell) and plugged the a6300 into a Tethered Tools case relay to get uninterrupted power. The SanDisk Extreme pro lasted about 15 minutes, while the Prograde lasted the entire 30 minutes.

Now, here is the interesting thing, the Prograde V60 are USH-II cards. (you’ll see that the cards have more contacts). Once we moved to those cards, the camera stopped overheating and we can reach the “imposed” 30 minutes recording that the camera provides, effectively doubling the recording time we get from it.

Interestingly, the Sony a6300 does not have a UHS-II slot. Nonetheless, UHS-II is compatible with UHS-I so there were no compatibility issues. For me, the next thing is to test the camera outside the studio. It’s 40 degrees centigrade here, so that would be an interesting test. We also want to test other UHS-II cards to see if this behavior is specific to the ProGrade cards or to any UHS-II cards.

    Nice to know that the newer card allows more time.

    Is it really an overheating issue or a buffer filling up issue?

    I’ve had hacked gh2s stopping early with slow cards as the buffer runs out, you said the sandisk writes around 90mbs but you where recording at 100mbps.

    With the hacked gh2s scenes with lots of movement filled the buffer faster than mostly static ones, could be worth trying a similar test with a river or such.?

      you never can be really sure, but we ran the test in an extremely cold room to verify, and did not get the overheating error notice, so I think so…

        DId you mean extremely hot, I would doubt that it would overheat when its cold, did you try it outside yet?

      The Sandisk Extreme Pro cards are rated at 90MB/s read speed but around 45MB/s write speeds. Cameras record at typically 100Mb/s. Notice the small ‘B’? That’s bits, not bytes. My Nikon D500 records at 160 Mb/s which is roughly 20MB/s. Easily handled by the Extreme Pro cards.

    How is it products are being released as working when they come with issues – why isn’t there protection for the consumer for this stuff
