  • SD cards come in all sort of read/write speeds. Sony Rx100 VII SD cards and write speeds? Stills - Video
 
How about fast batch/burst shooting or 4K video? Is 80 mps write still fast enough? I ask because I have a drawer full of 80 SD cards.
 
Yes, but i don`t have your camera specifically. I don`t even know what buffer these cameras have.

Some testing might be required.

If my previous experience serves me right, a sdxc(not sdhc) memory card that respects UHS I standard(minumum 80 mb/s write speed) will be capable of recording 4K video at ~100 mb/s.

With burst shooting the buffer is more important, since no memory card i know of can keep up with modern cameras. Bursts are stored on the buffer memory, then they get transferred to the memory card.

Interesting. A new field for me. Love to be able to use my "old" 80mp/s cards. Here are the stats for my camera:MP4/XAVC S
UHD 4K (3840 x 2160) at 23.976p/25p/29.97p [60 to 100 Mb/s]
Full HD (1920 x 1080) at 23.976p/25p/29.97p/50p/59.94p/100p/119.88p [16 to 100 Mb/s]
AVCHD/MP4
Full HD (1920 x 1080) at 50i/59.94i [17 to 24 Mb/s]

If that 80MB/s rating is printed on the card, it's the read speed. Normally you have to look up the write speed rating on the vendor's website. Good retailers will also list both read and write speeds.

By far the most important rating to look for is the U3 or V30 speed class rating. It should be clearly marked on the card. That rating guarantees a minimum write speed of 30MB/s. That will meet all the requirements of any current Sony compact camera.

There's only a minor price differential for fast write speed UHS-I cards (90MB/s). However, your camera can't take full advantage of those cards. Probably only worth it if future proofing. If your cards are U3 rated, format them in the camera and you're good to go.

You may find that your card is technically fast enough but will still not offer the faster bitrates at 4k.

To guarantee that it'll work you need a U3 SDXC card.
 
Thanks, all!

When I bought my RX100M6 the first thing that happened when I tried to set to 4K 100mbps video was that the camera told me "go buy a faster card, muggins". Well, maybe not exactly those words, but it thought my usual bucket load of plain jane Class 10 SDHC card were not up to the task.

So I bought Sandisk Extreme 64gig SDXC U3 V30 cards that were rated at 60MB/S and had no further arguments with my camera. Takes 4K no hiccups, but a boring long wait to write the buffer out if I do a huge stills burst in my attempts at image stacking experiments. I don't think the M6/M7 have a very fast write capability and the very top speed cards would probably be a waste of money.

Pulled the card from my RX100M6 and that is what it looks like. The "150MB/s" of course is only the read speed, visiting the specs at WD the write speed is rated as "up to 60MB/s". It works OK for me.

Latest visit to WD shows the Extreme card as 90MB/s though the text says "up to 150MB/s read speed" and now the current cards seem to be rated at up to 70MB/s.

 
Yep. My 10 cards don't work for video. Great info on this site you just have to be patient. Thanks much!

When I get to go on a holiday (well, that's finished for a while) I tend to review my card stock and maybe buy a few more at the current sweet spot for size vs $. So a motley collection over the last few years of previously Class 10 SDHC 8/16/32gig cards.

Of course no good in the M6 so moved to the 64gig SDXC U3 V30 cards because of the M6 and now they inhabit the two M6 in the family and also my various M4/3 bodies, hence the tape labels on the cards to keep some semblance of order.

I used to advise against all eggs in one basket with bigger cards, but they have proved so reliable (touch wood) that a couple of 64gig cards will see me through any big holiday, plus of course a selection of those Class 10 smaller cards as backup just in case. I do stills mostly so don't miss video if not available.

The only warning is to never buy cheap eBay deals on cards as it seems that about 90% are fakes. Only buy from reputable sources. In Australia I use officeworks.com.au (stores) and cheapchips.com.au (online). I buy from who is best at the time.
 
Hi guy,

Yeah, the 10s just sit there. Cards are cheap now! I NEVER buy anything from eBay. . . anymore.
