ProGrade Digital 256GB UHS-II SDXC overview

  • 1Description

The 256GB UHS-II SDXC Memory Card (2-Pack) from ProGrade Digital features a storage capacity of 256GB and takes advantage of the UHS-II bus to support maximum read speeds of 200 MB/s and maximum write speeds of 80 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 optimized for 4K, 3D, and Full HD video capture, as well as 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 (2-Pack) 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. A built-in write protect switch helps to safeguard your content from being erased.

    ProGrade Digital 256GB UHS-II SDXC reviews

    256GB UHS-II SDXC Memory Card (2-Pack) is rated 2.4 out of 5 by 10.
    Rated 1 out of 5 by from Both cards failed within 2 weeks Seeing the specs for these cards, they should work just fine in the Panasonic EVA1, but after about 100GB of footage written to them, both cards failed spectacularly. The first card was recording at 150Mbps, and after about an hour, just stopped. It couldn't be recognized by the camera or the PC and all the footage was lost. The second card was then tested immediately afterwards with the exact same results. It recorded fine for the first 1/3 of the card, then failed. Once inserted into the computer they only read as 7.61GB. I've tried multiple recovery methods, and then just trying to format the cards with no results. They are absolutely useless now.

    Rated 5 out of 5 by from Responded well to testing Bought these for my EVA1 to meet the v60 requirement for All-I 400mbps capture. Both 256GB cards formatted without issue. No warnings about compatibility when loaded like you see with some other cards. Each will hold 85mins of DCI 4K, 400mbps All-I, 23.976fps. 170mins total. I burned off short clips of a few minutes in duration to both cards. Played clips back. No errors. Went for long takes of more than 60 mins next.� First card successfully captured an uninterrupted 81 minute 400mbps All-I clip. Second card ran in slot 2 for 83 minutes without issue. Then I swapped the cards so they'd each be in a different slot and set recording to "simultaneous". Filled both cards with an identical 82 minute unbroken clip. Again, 400mbps, All-I, DCI 4K at 23.976fps. Happy to report things look promising for these SD cards. A few days later, I was hired to shoot an EPK piece.� Threw everything at these cards: high frame rates, All-I, LongGOP, simultaneous capture... they performed without issue.

    Rated 1 out of 5 by from Corrupted my Panasonic EVA-1 Footage within a week I got these cards as they were rated high enough to be able to handle Panasonic EVA-1's 400mbps 4K codec but as soon as I put them into my EVA-1, it started showing up errors. After a bunch of formatting and reformatting, it finally started working. However, about a week later when I used them for an actual shoot, after about 2 hours of shooting, the cards showed and error and again, and wouldn't even show up on my computer. They were completely rendered useless and corrupt and I lost all the footage. I would recommend going with a V90 card and maybe smaller size as well as that may have added to the instability, but for a card that says it should work on the EVA-1, I was highly disappointed.

    Rated 1 out of 5 by from Do not buy I have been using with out any issues for 6 months on my first set of these cards and decide to buy more. One week later I have 2 corrupt cards. One has a failure due to hardware and is completely dead. The other had a software failure and lost all of the footage. It looks like a issue with cheap gold connectors. I've used the same San disk card for 5 plus years and it doesn't have close to the wear that theae cards have after a few uses. The gold connectors have deep groves in them after being Removed bed from the camera twice. It seems very hit or miss on the quality.

    Rated 5 out of 5 by from Working with Panasonic EVA1 400Mb/s recording We purchased this two-pack for being the most affordable and fully compatible cards for our camera's 4K video recordings. We tested both cards before using them for work and so far we haven't encountered any issues. Something to note: ProGrade looked into failures that were being reported and identified a firmware update to discourage/prevent these failures.

    Rated 1 out of 5 by from Warning: Do not trust for professional work! I had two of the V60 cards for use with my GH5, I should have known better as this is below recommended specifications for the 400mbps but for all my tests it performed very well so I trusted them enough to use them for a high profile client for my television station. Both cards corrupted and could not be recovered. I wasn't even shooting in the 400mbps mode, I was in 10 bit 1080p at its highest setting, something my years old Sandisk cards can do without issue. It cost us a day of work and I will never trust this brand again.

    Rated 1 out of 5 by from Don't buy these cards!!! I bought 4X 256gb v60's to shoot timelapse (total over $650. Shooting 1 frame per second on two of the cards with no sidecars (just RAW 36mp) on my Canon 5dMkIV and both cards fail on two separate cameras. Err 002. Cards partition was lost drive converted to raw and even running a slew of high quality data rescue programs (ease, testdisk, cmd) the shots are lost. Never in all my time shooting have I had this spectacular of a failure with my media. I've had data bottle necks, buffer lock ups but never a complete card failure; even if the write speed is too slow (which it isnt in this particular situation why would the card be corrupted? Perhaps there is a bad batch of sd cards? I even ran a test on the 3rd card and the same exact thing happened. Many hours of work down the drain. Very disappointed and angry

    Rated 5 out of 5 by from Great cards! I was looking for some new cards for my Sony cameras. I have both of the UH-2 cards from Sony and they work great but are expensive. Now they are back up cards and run one of these cards in both cameras. I have an A73 and an A7R3 and have had no issues with both photos and 4K videos.
