Expensive but better constructed.

I pull my cards often to edit this is strong enough to stand up to the riggers of removing and replacing cards in computer and camera.

Card Error !!! Lost all photos and videos !!!

I had one of the card which should be replaced by Sony as a card which can be defected. I applied for replacement and Sony didn't contact me back for weeks. Today I had a Card Error and I lost all photos and videos. Never again Sony. I back to SanDisc.

Best SDXC Cards I've Used (Especially with the GH5)

I mainly use Sony SDXC cards while operating cameras at work--at home I still use various SDHC brands. When I upgraded to a GH5 however, I knew I'd had to purchase faster cards to match the much faster 4K bit-rates. The Sony M series does not disappoint. Lighting fast, even at my cameras highest settings (4K All-I 400mbit)! Excellent build quality, too--and not quite as heavy a hit on the wallet as the Sony Tough series cards are, which I'm not sure are worth the price unless you'll be using them in the rugged conditions they're designed for. Can't go wrong with these cards is all I can say.

Good price for a fast card

Card has worked well and is fast on a USB 3.0 reader. Makes it faster to transfer photos to the computer. I have not noticed any differences in camera operation.

Fast as lightning, no more waiting to take photos

I love this card. I have a Sony A7III and use it on hi-burst mode for concert photography. With previous cards like the SD-UHC I SanDisk Extreme, I had to sometimes wait for the camera to write to the card in order to continue shooting - when the moment is everything, that's the opposite of ideal. With this mem. card, I can take continuous bursts and never have to stop to wait for the card to write. The 128GB size also gives me the freedom to not worry about switching out my card to capture more - between my 128 and the other slot which has a 64gb (and a camera setup that writes on to the other card one is full) I have yet to hit my storage cap. It also reads at least 20% faster than my other cards, meaning I don't have to wait as long to get everything in to Lightroom.

Fast card and great value.

Bought this for my Sony A7RM3 and it works a treat. Although I do not do video, I find it is ideal for stills shooting.

Work great for the Fuji X-H1

Have these in the Fuji X-H1 and have never had an issue. Will hold 1-2 hours of HD video or ~1k compressed RAW photos no problem.

It works, but...

As far as handling 4K ProRes HQ footage on a Blackmagic 4K Video Assist recorder, it seems to be doing the job, no dropped frames. It indicates that it reaches its advertised write speed of 100 MB/s. However, in a tested Lexar LRW400U Rev A UHS-II reader it shows write speed of 61.9 MB/s and read speed 90.1 MB/s. The same reader shows 150+ MB/s write speed on a Lexar 2000x UHS-II card. It's a possibility that somehow the reader cannot take full advantage of this card UHS-II interface, but aren't all UHS-II cards supposed to comply with the same standard?

Works well with the A7R III

Operates well when used with the Sony A7R III. Before purchasing the Sony 64GB SF-M Series UHS-II U3 Class 10 SDXC Memory Card, Maximum 260 MB/s Read - 2 Pack, I used older SanDisk memory cards. Unlike the older cards, this card does not lag behind per my shooting style. At the time, I purchased an extra one as a back up. I would recommend this card to a friend.

Work Great for anything the Fuji X-H1 can do.

Have these in my Fujifilm X-H1 and haven't had any issues for holdups due to the speed. Download speed onto my computer seems pretty quick as well. Nice cheaper option for UHS-II.
