Anyone recommend the best card or cards for use in the K3III please?

I am staggered at the price of UHS-II Class 10 cards, but probably need to bite the bullet if I'm to get the best out of my new toy?

Or would I really notice the difference if I went for something lesser, aka cheaper?

Transcend seem to be the cheapest at the moment of the brands I've used before. The spec you need to look for is V90 which is the minimum sustained write speed (90MB/s) vs V60 or V30 which are 60 & 30 MB/s respectively. You're right though, prices are bananas right now.

Thanks for this. Any particular Transcend card? Have you run a real world test to see just what the difference is between a V90 card and lesser ones?

64GB Transcend 700S SDXC UHS-II U3 V90 SD Memory Card CL10 285MB/sec MLC Flash

38 from a memory supplier in Ireland, memoryc.com

I've a couple due in and will test on a USB 3.2 port with USB Type C reader next week when they arrive. Normally I run SanDisk extremes but they seem to be @ >75 of whatever currency you choose.

Thanks. Good prices. 34.00 delivered. 1.00 less than a Prograde V60 card I've ordered.

Ordered the Transcend card. Will be interesting to see how the two compare.

I finally got around to testing the speeds of the Transcend card.

Read measured by Aida 64 came in at a stable 270MB/s




Write I measured with Sisoft Sandra 2020 and it was a bit more up and down but still impressive varying between 120MB/s and 220MB/s




Finally I tested it against CrystalDiskMark 7 - Reads are lower but writes are stronger.



All in all, looks to do what it says on the tin without extravagant pricing.

Very interesting. Thanks. I haven't yet had an occasion when I've needed to use the cards performance to any extent, but it's good to know it shouldn't let me down.

That said, and perhaps answering my own original question, the best card is the one that supports the anticipated use of the camera.

Fast action, video, etc., = high performance card. Landscapes, portraits, etc = any high quality card.

I've bought cards in anticipation of video usage, but haven't yet tried this function.
