The 256GB UHS-II SDXC Memory Card from ProGrade Digital features a storage capacity of 256GB and takes advantage of the UHS-II bus to support maximum read speeds of 250 MB/s and maximum write speeds of 130 MB/s. This card has also been designed with the V60 Video Speed Class rating, which guarantees minimum write speeds of at least 60 MB/s, allowing the card to be used in DSLRs, mirrorless cameras, camcorders, and digital cinema cameras to produce 4K, UHD 4K, 3D, Full HD, and high bit rate MPEG-4 video. It is also well suited for raw photos and rapid-fire bursts. UHS-II cards achieve their speed through an extra row of pins and while this card has been designed for cameras that are UHS-II / V60 compatible, it may be used in devices that do not support UHS-II / V60. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-II and V30, which supports minimum write speeds of 30 MB/s, or UHS-I and U3, which also supports minimum write speeds of 30 MB/s. If your device does not support U3, this card is compatible with the U1 and Class 10 standards, each of which guarantee minimum write speeds of 10 MB/s. Built for extreme conditions, ProGrade Digital's 256GB UHS-II SDXC Memory Card is able to withstand temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments, such as snow and deserts. It is also X-ray proof and shockproof, and a built-in write protect switch helps to safeguard your content from being erased.

I have used SanDisk with my Cannon for a number of years and loved them. I got a new Olympus E-M1x and it seemed the Extreme Pros I had couldn't keep up with the M1x buffer (ie. Long waits while it emptied). The E-M1x has a UHS-II capability to handle heavy data storage requirements. So, I tried a couple of other brands, who's names I won't mention, but the reliability wasn't there. So far, with ProGrade, after about 3 months of shooting, no problems with my Prograde 64GB UHS-IIs. I reformat after every use. No glitches, no lost images, I can even shoot raw at 60 FPS and not saturate my buffer too quickly. 4K video is no problem either. ProGrade also makes a silver label 300MB/s V90 that is even quicker when to storing very large volumes of data.

At the time of this writing, the SanDisk UHS-II are more expensive and only guarantees V30 writes. The V designates the minimum speed the card will write at under load. A V30 guarantees at least 30MB/s writes, a V60 = 60MB/s writes, and a V90 writes at least 90MB/s.

We upgraded to prograde cards after having lexar cards cause several write issues in our various sony alpha cameras. We've got 5 sets of these now and they've all performed flawlessly over the last two years. We record mostly 4k 10bit @30fps, but have had no issues with occasionally shooting at 60-120fps.

I have dozens of SDXC cards acquired over the last few years for use in my Sony RX100M6 and Canon G3X and G7XII cameras, and I have used Sharpie markers to note on the label on each card a unique card id, so I can keep track of which memory cards I've captured photos and videos on during multi-day shoots. Unfortunately, the ProGrade card label is coated and neither a Sharpie nor a ballpoint pen can make a readable mark on it. But, a customer support person at ProGrade suggested that I use the smallest round Avery labels and Sharpie Industrial Permanent Markers, which I then bought at an Office Depot store. The combination of Avery label and Sharpie works great for me. See them in photo below. Kudos to ProGrade for solving my problem.

I thought I would try ProGrade as an alternative to the expensive Sony SD cards for my A7R cameras. Big mistake. On the 3rd use of the card I shot 600 photos. No apparent problems until I got home and tried to import them onto the PC. Copied a few files then the process stopped with a media error. Tried to eject and then reinsert the card and the PC could not even detect a file system (asking if I want to format the card). Yikes. I downloaded the expensive ProGrade recovery tool and it could find all the files. Sony offers a media recovery tool for free! I never had any problems with Sony media cards. Never. Why trust this brand? Why trust a company that does not at least provide the recovery tool for free to owners of their cards? Back it goes for a refund.
So far, so good. Matt Meisenheimer recommended Prograde on a Backcountry Journey's trip and he was right. My previous Prograde SD card is still going strong. Other brands, and I'm looking at you, Sony, have had problems. The lock slide fell out of one. The casing of two others split off bits and now they won't go into my Sony cameras.
They do what you want reliably and store a lot of photos. PProGrade is all I use these days. But B&H, two tiny SD cards came in a shoe box sized box with lots of bubble wrap. I appreciate that you want to avoid shipping damage but that large box for two tiny SD cards traveled across the country on FedX trucks. Seems like a waste to me.
This is my second set of these exact same cards. I use them in pairs for simultaneous backup of both stills and video on my Fujifilm GFX 50S and X-H1 and have never had an issue with them. With a v60 rating, they’re fast enough for everything I do and have never become a bottleneck, even on the GFX with its large, uncompressed RAW files or on the X-H1 when shooting 4K. And someday, if I ever do run into a card issue, I’m confident ProGrade will be there to sort it out for me.Finally, if you don’t need the extra speed provided by the platinum series cards, the gold series are excellent value. I would rather save money than have speed I can’t use and apply the funds toward bi-annual card replacement/cycling to reduce the chances of card failure.
ProGrade has rapidly become an industry leader in speed, performance, reliability and support. I have both V90 and V60 cards and use various Sony mirrorless models-- A7riv, A7sIII, A1. The V60 cards are a bargain, particularly in the 2-pack. While they will not achieve top 30 fps speed in A1 continuous still shooting, continuous shooting is still a possibility perhaps even up to 20 fps JPEG, a bit less compressed RAW. What is significant is that in both the A1 and A7sIII, this V60 card supports 4K 60p video. While you need to go to the Sony CFastExpress A cards for 4K 120p, these cards are a great economical high capacity 4K medium. I would not hesitate to buy (have several in addition to this purchase) or to recommend.
I bought these because of the price and rating. They work great right out of the box. The read and write speeds are as advertised. I use them in a dual SD slot with simultaneous writing and neither have failed in the weeks I've had them. I will update in a year.
I felt like there is a lot of conflicting information about the use of UHS-II cards in a 5D Mark IV. I started using these cards recently in conjunction with San Disk Extreme Pro SD Cards. These cards perform really well in a 5D Mark IV...slightly faster than the San Disk SD cards. My tests aren't very official or scientific, but the Prograde card was able to hit 29 shots before maxing out the buffer while my San Disk cards were hitting 26 (my CF cards were hitting around 35 frames). The buffer seemed to clear a little faster as well. Again, these aren't official tests, just my real world observations. I've been using it to shoot some 4K video recently as well and it's been working really nicely! I paired these with the Prograde card reader and download speeds are ... MoreI felt like there is a lot of conflicting information about the use of UHS-II cards in a 5D Mark IV.

A huge lifesaver for me, I consistently shoot 40-50 gb of photos in a day of shooting.If these cards hold up in the long run, then I'll be a customer for life.
