The 256GB UHS-II microSDXC Memory Card with SD Adapter 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 optimized for 4K, UHD, Full HD, and 3D video captures, 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 microSDXC Memory Card with SD Adapter 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 resistant against x-rays and shock. Included is a microSD to SD adapter, which allows this card to be used in devices with full-sized SD slots.

Bought these to make use of the S&Q mode on my A7M4, so far no issue with the card.Minor - ComplaintThe only con I have is the adapter feel a bit flimsy compare to my Samsung PRO MicroSD Adapter(UHS-I), don't know if this an issue with UHS-II adapters, also the toggle lock switch is a bit loose, and rattles.

These things are tiny but capable. My recent purchase was the first time I got a micro card to use in my drone. Make sure to get the SD adaptor_ that way you can download contents to just about any device and since the micros are so small they ad some security_the SD adaptor is about 4x the size of the micro so its much easier to find if you drop or misplace it. It also enables you to carry the micro cards in a card wallet that you'd also use to carry any SD cards. A must have combo.

Card is fast and works as expected. Card adapter got stuck in my Mac due to sandwich design. Would suggest reworking this design to remove the edges that can catch on a tight slot.

Wow. I wasn't aware that UHS-II Micro SD cards were becoming a thing. I've been using the UHS-I, U3, V30 A1/A2 cards for my Mavic 2 and Mavic 3. They work fine, but offloading footage is under 100MBps, and slower than any other cards I have. When working with 100's of GB of footage, that means many minutes waiting for a copy operation. For $100, I'm doubling my transfer speeds to 200MBps, saving half the time it used to take me. And, I'm future proofed in case DJI ever starts using UHS-II for recording. Haha, that would be great. Last thing... these come with a UHS-II Micro SD to UHS-II SD card adapter, something I haven't seen ANYWHERE else. It's super convenient, as I don't need a special adapter, like the Kingston Micro SD cards come with.
I ordered two (2) of the 256GB 250Mb/s V60 micro SD cards. Both of them will only give me 239MB of free space. What happened to the 17GB of space? If it takes that much room on the card to control it, there is something definitely wrong. I formatted and reformatted both cards a couple of times to see if I could regain the majority of the lost 17GB to no avail. Though I have lost that much space on each card, they will work for my situation, so I am not going to return them. I do feel cheated though.
I've had some recent issues with sandisk cards, after using for most of my camera devices, especially go pro after speaking with tech specialist, I'm glad I switched to pro grade. No issues so far.
It’s my second review for Prograde. I’m loving their fast SD cards! They work super sufficiently and keep my footage safe.Great quality and excellent customer service! They always ship super fast as well.And I even got a card holder as a gift with my last purchase! Was very nice of ProGrade. Also big thanks to John who always helps with any question I have!
There is a real need for speed when you have 10 to 20 gigabyte files to move around from GoPro cameras. These are the real deal.
Whilst good in most regards, I've had big compatibility problems with reading in a M1 MacBook Pro's internal card reader. It hangs the whole system for ages. No amount of reformatting or zeroing out can help.
Picked this up from B&H because of their service from previous purchases and it arrived ahead of schedule....The ProGrade Micro SD Card was purchased for a new 4K dashcam. The Cam required a U3 speed card to make sure of it's performance while taking 4K video. I opted for the V60 and the larger 256GB with 250MB/s transfer speed to make sure there were to be no problems. I have not been disappointed and look forward to a lifetime of service from ProGrade (I am 71, so 25 years should do just fine)
