On a quest to try and improve the hit rate on my A7RIII. One issue is hesitation between shots during a burst, some of which is due to the camera slowing when the buffer is full. I hoped a card with a faster write speed would make a noticeable difference over the Sony Tough 277/150. I decided to try a Kingston Canvas React 300/260, which gets excellent reviews and is less costly than the faster Sony, just in case it turned out to be a waste.
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 pretty much the same result each time:
I might try it in the A7IV to see if the newer/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.
