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

If youre looking for dependable SD cards for the GH5s high bitrates, youre 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 didnt work in that mode. But... I only shoot in Relay Rec mode. And no issues, no choking so far in that mode. I normally dont shoot in All-Intra/400mbps for my clients, but its 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 youre looking at about 40mins in total for both slots. Dont get scammed by the V90 craze! Its just a cash grab, at least for All-Intra on the GH5. Youll have plenty of breathing room when shooting at any other bitrate as well.

Needed something fast for high-quality HD video, and this is it. Sucks-up the bits like nobodys business.

Everything I expected.

Tested with Crystal Mark, came out with average of only 93 Read, 74 Write! Wasnt happy. Then realized it may have been a limitation of my USB 3.0 card reader that was keeping the numbers low. Put the card in my GH5s, shot some 4K 400 All-I, and the card seemed to handle it fine (I let it run for about 4 mins). As a comparison, I then tried my Sandisk Extreme Pro 95 card, which actually had higher CrystalMark write number (88), and that card didnt last more than 5 seconds in the GH5s 4K 400 All-i before camera shut down due to insufficient card performance. So, it seems to work.

Great product very fast transfer speeds

I purchased this SD card after spending a considerable period of time researching the safest one to buy, because I really did not want to loose any of my data. And what do you know, two months later and the SD card randomly corrupts, meaning I lost all of my footage. The free SD card recovery programme offered by Sony did nothing to help recover it. Amazon did nothing. Sony also did nothing to help. Extremely frustrated and disappointed. I was using the SD card with a GH5.

no hay queja alguna. excelente producto, lectura y escritura excepcional. la uso en mi nikon D500 totalmente recomendado

Works as advertised, great product, would buy again.
