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

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.

Good! Works well with my mirrorless photo and video. Sony A7r mark ii and Sony A7s Mark ii

This unit is ‘post-recall’ - has the star in lower corner. Works nice.

You really have no choice if you are using the Z7. This Memory Card works perfectly, is well made, fast and easy to handle. It takes a special USB reader to connect to your computer. So the entire package is a bit expensive. But considering the investment in camera equipment and the value of getting the shot, its really not that big of an expense.

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/s Sequential Write : 99.091 MB/s Random Read 512KB : 200.910 MB/s Random Write 512KB : 0.871 MB/s Random 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]

I just ordered and received the 128gb card, now I have speed and a larger card, which I need with the a99 ii. I suppose we learn best from experience. This card is all that I hoped it would be.I can set my shutter on 5 fps, shoot and the camera doesnt have to wait for the card to write the data. Slot one on my a99 can be either the Sony SDXC UHS-II or a SanDisk memory card. I cant get more technical than that. The Sony memory is so much faster and uses the cameras capability. Sony is much more expensive but it is so much nicer.

To be honest, I purchased this SD card after more research than probably necessary. It works great with my Sony A7iii and is priced right.

Super fast and reliable. I love it!

Have used these cards consistently for a while now with my a7iii. Absolutely no issues whatsoever. Very fast! But to get full potential, make sure you have a fast card reader that can give you an understanding of just how fast this is. You will also need to check if your current card reader is UHS-II compatible. Mine was not and I had to upgrade.

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.
