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

Good

The 64 gig size of card seems to be a good size for weekend trips. It too early to know what there durability will be.

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

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.

Worked as expected! Cant wait for these things to go down in price!

As expected

Perfect. Does what its supposed to do in my camera. Havent had any issues in the Sony a7iii

Fast, huge, capable. What more can a photog want?

I purchased this Sony memory card for my new Olympus mirrorless camera. I needed something that would be reliable while shooting at various sites. This card has worked perfectly so far.

This card is rated for 150 MB/s write and 277 MB/s reads. It met the write speed on the dot and the read speeds are pretty close.
