In another thread I mentioned that I had ordered a faster SD card in an attempt to clear the A7RIII's buffer more quickly. I've been using the Sony Tough 277/150 and hoped that bumping the write speed would have a significant effect. I decided to try a Kingston Canvas React 300/260 based on reviews and cost, figuring if it didn't make a big improvement I wouldn't be out much.
Testing was simple. I activated the buffer display and pressed the button until the line disappeared and 'slow' appeared, then timed how long it took to clear the buffer. I ran this test with both cards several times and came up with the same answer:
So...meh. Certainly not enough of an improvement to make any kind of noticeable difference in use. The 'slower' Sony tough card is $69, the Kingston is $82. I'd rather have the 'slower' Sony Tough card.
I might try it in the A7IV to see if the faster processer can put the card to better use. If not, I'll carry the Kingston as a spare. I have more trust in the Sony cards.

- The Sony 128G 277/150: 27 shots to full, and a touch under 15 seconds to clear.
- The Kingston Canvas React 128G 300/260: 28 shots to full, a touch under 14 seconds to clear.
