ADATA Premier ONE (64GB) Class 10 UHS-II SDXC Memory Card, black

Thumbs up, has as an actual capacity of 63.18gb. Read & write speeds - I got a near constant, well a good average R/W speed of 277/249 for a 15 minute movie transferred from the card to Mac Book Pro & vice versa. This is only my second card to date and now using the original as a back up. Price I paid for the performance far exceeds the big named brands.Life time warranty too which reassures me.Only time can tell although haven't had a problem or error yet. Using the Nikon D810 btw. This review could well come back and bite me hard BUT I'm willing to keep buying Adata cards, would seem silly not to.The card I received has 2 rows of gold contacts unlike a review another Amazon member has posted.

I bought this memory card last year and have gotten some really good use out of it but literally yesterday night, I began to experience writing errors. At first I thought it maybe down to my camera but after putting the card through a speed test, it is clear the card has some how become abysmally slow when it comes to writing speed. I shoot on a Panasonic GH5 so I am dependent on these faster cards and the fact that my primary card has become so slow with writing speed is a huge disappointment considering how much I spent on the card. I expected to get a few more years out of it. I suspect that the time lapse function on my camera is what caused the writing speed to slow down as Ive set the camera to shot both JPG and RW2 files, but given the fact that I occasionally do this, I expected the card to be able to handle it. Although am still not entirely sure what caused this, I am still hugely disappointed.

Bought this Adata 64 gb SDXC ii u3 290MB/s for my Canon 80d DLSR camera. A camera with 26 mega pixels.The 64gb card is more than enough for this camera. I shoot in raw only so still has space for at least 700 pictures.This card is faster than the camera can write too, so video and burst mode is flowing and fluid. I bought in case I replace the camera with one higher spec or more pixel count or faster write speeds. I have two 64 gb cards now for a travel trip coming up. Having two cards doesn’t keep all you eggs in one basket. Having this card also enables me to use in any divice that has SD slot. Files transfer fast and effectively to my iMac. Can’t comment on how long it will last. Why I have to cards, both different manufacturers .

Really bad card. First use and it stopped working.I was filming with this in a wedding ceremony and the card just died.No response. I tried recovering it with software means and nothing.Now I have sent this to a Forensic Data Recovery company just to get my footage back.And I will end up paying £500 for my mistake.Pay cheap - Pay twice (or 10 times in my case).

Kept getting low speed warning bars when shooting normal HD on canon 80D. Then recording was stopped. A problem I've only ever had on slow cards. Spent the extra for reliability. Sticking to integral Ultima pro now, half the price for double the capacity and shoots flawless HD video all day long.

it's the best so far for the Panasonic GH5

Got this to record 4k 10bit 422 400mbps on the Panasonic gh5. Fills up fast (64gb) but WORKS! i tried delkin previously and no cigar.

This card is not UHS ii... only one row of pins on this card, not two as uhs ii cards are
