Best SD Memory Cards For The Sony RX100 V


Sony over the last few years Sony has done a great job with enhancing their firmware to allow more memory card compatibility. It use to be that you could only use SDXC memory cards when recording 4k footage. Now SDHC and SDXC memory cards are both compatible. Now to shoot 4k you’ll only need to make sure you’re using U3 memory cards.

While the camera has a massive buffer, allowing you to shoot 71 frames, you’ll have to wait close to a minute for it to clear since the camera is fairly slow at writing to memory cards.

 

Sony RX100 V Memory Card Speed Chart

A lot has changed in how I tested the Sony RX100 V. This time around I found the ready light hidden in the battery compartment, so my test is way more accurate.

Like the previous cameras and all of Sony’s other cameras, it seems to have a pretty nasty bottle neck. It takes almost a minute to clear the buffer on most cards.

Also, if you’re wanting to shoot 4k video, a lot of cards are still hit and miss. Stick with U3 cards and you have a better chance, but no guarantee. I recommend you buy Sony memory cards, they seem to work the best.

Another thing to point out compared to the Sony RX100 IV test is, I retested all the USB 3.0 read and write speeds with Windows 10, which seems to improve speeds some.

Recommended Cards

I’ll list the Sony again here since it is a great performing card with this camera. And I also like the PNY cards for performance, price and cost.

Sony RX100 V Speed Tests Summary

Speed tests seem almost identical across all cards. However USB 3.0 speeds can vary significantly. 

Also, even though the speeds seem to be the same, choosing the right card still matters so that you can record XAVC S 4k Video, which again, is a U3 card, preferably by Sony.

 

 


Shooting 4k On The Sony RX100 V – Stick with Sony Brand!


Recording 4K video requires SDXC U3 memory c​ards!

If you want to shoot 4k on any Sony camera right now I recommend only using Sony brand cards. A lot of people have problems with other brands right now, and it’s actually not the cards fault, it’s the cameras fault. One card will work fine in one camera but then not in others.

Why Some Cards Don’t Work

Even though all the cards run at about the same speed when shooting RAW images, the camera will notice if you do not have a U3 SDXC card and not allow you to shoot 4k 100M video.

This is weird to me because I’ve tested it with cards of the same speed. And when I format a U3 card, then shoot video and immediately replace it with a U1 card without formatting, the camera will let me shoot video on the U1 card. But when I freshly format a U1 card I get this message –

“Cannot record this recording setting, Either switch to a UHS-I U3 compatible memory card or change the file format.”

So to make your life simpler, get a U3 card and it must be SDXC or SDHC to shoot XAVC S 4k video.

You can still shoot AVCHD 1080 video on a SDHC U1 card. If you don’t mind working in that codec and at a lower bitrate.

 


UHS-II Cards In The Sony RX100 V – Will They Work?


The Sony RX100 V does not have a UHS-II interface on it. So any UHS-II card you put into the camera will be clocked down to UHS-I. It’s fine if you want to use UHS-II cards for fast USB 3.0 transfer speeds, but you won’t see any real benefit in camera. I also think you might run into more problems trying to shoot 4k video on a UHS-II card.

 

 


Best SD Memory Cards Sony RX100 V Conclusions


Based on all the tests, the speeds and the video requirements, the best card you can get is a UHS-I U3 memory card. Although Sony brand cards don’t perform the best, Sony cameras just seem to like them better, go figure.
