Sony M Series SDXC UHS-II Card 64GB, V60, CL10, U3, Max R277MB/S, W150MB/S (SF-M64/T2), Black

The media could not be loaded. I bought this card in 2018 to use in my Sony a7rii for both, photos and 4k video and it has been an excellent working tool; still to this day in 2024 it continues to perform excellently with excellent speed plus it has the ability to save 8k video data.Cons: 64 gb of storage is too little for large digital video but still works for backup sd.

Excellent read speed in UHS-II mode. I benchmarked the card in several UHS-II readers and the highest benchmark was 269.0 MB/s in the Lexar Professional Workflow SR2 UHS-II. Write speed reached 99 MB/s in several card readers as well. This is a good card for those looking to improve their workflow with fast downloads. Its write speed is not much above what you can find in other UHS-I cards (Such as the SanDisk Extreme Pro 95MB/s UHS-I card), but the real improvement is the download speed.Sequential Read : 268.969 MB/sSequential Write : 99.091 MB/sRandom Read 512KB : 200.910 MB/sRandom Write 512KB : 0.871 MB/sRandom Read 4KB (QD=1) : 12.092 MB/s [ 2952.1 IOPS]Random Write 4KB (QD=1) : 2.624 MB/s [ 640.7 IOPS]Random Read 4KB (QD=32) : 14.369 MB/s [ 3508.1 IOPS]Random Write 4KB (QD=32) : 2.904 MB/s [ 709.0 IOPS]

If you're looking for dependable SD cards for the GH5's high bitrates, you're in luck. I purchased 6 of these 64GB cards. I ran multiple tests on my GH5 with these cards in All-Intra/400mbps mode...ONE THING TO KEEP IN MIND: When shooting in 'Back Up Rec' slot function mode I keep getting a message that says 'Backup recording requires using two identical SD Cards.' I didn't work in that mode. But...I only shoot in 'Relay Rec' mode. And no issues, no choking so far in that mode. I normally don't shoot in All-Intra/400mbps for my clients, but it's good to know that these cards handle the demand if I ever needed it (i.e. for a short film, feature film, etc.). You get about 20mins on one card slot of the GH5 with these 64GB cards. So you're looking at about 40mins in total for both slots. Don't get scammed by the V90 craze! It's just a cash grab, at least for All-Intra on the GH5. You'll have plenty of breathing room when shooting at any other bitrate as well.

Hay memorias que han durado más tiempo, esta ya me está dando problemas, si que la uso mucho pero otra sony G me ha durado más tiempo sin problemas. Pero esta bien

I like the speed on this. I can shoot pictures in burst mode and it handles them very smoothly. Price wise is also very good and not that expensive. This is great for shooting 4k Videos also. I use them with Sony a7III.

I have these in several machines and they work great. Love being able to see the prints being made.

Highly recommend these cards! I have been using them in the 32 and 64GB flavors for about 8 months and haven't had a single issue with them. Rock solid performance and reliability. I recently upgraded to the G series card(for the UHS-II slot) and if you need the extra speed I'd recommend it, blazing fast buffer clearing!

It's a good and quality product, thanks Sony!/Before that I was using these ones: SanDisk 64GB Extreme PRO SDXC UHS-I Memory Card (SDSDXXG-064G-GN4IN) ---- NEVER BUY THEM!!!!! THEY ARE MADE OF VERY CHEAP PLASTIC!!! ONE RUINED MY Sony A7rII SD- card slot!!!. /.This Sony card is very good! Highly recommended!!!
