The 256GB EP UHS-II SDXC Memory Card from Patriot features a storage capacity of 256GB and takes advantage of the UHS-II bus to support advanced DSLR functions such as continuous shutter bursts and rapid shooting, as well as raw and JPEG captures. This card is also well-suited for video capture, including 4K, 3D, HFR, and Full HD video, and can achieve maximum read speeds of up to 300 MB/s and maximum write speeds of up to 260 MB/s. Thanks to its V90 speed class rating, minimum write speeds are guaranteed not to drop below 90 MB/s.

UHS-II media achieves its speed through an extra row of pins and, while this card has been designed for cameras that are UHS-II / V90 compatible, it may be used in devices that do not support UHS-II / V90. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-II and V60, which supports minimum write speeds of 60 MB/s, UHS-II and V30 or U3, or UHS-I and V30 or U3, both of which support 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 guarantees minimum write speeds of 10 MB/s.

As with most Patriot cards, this memory card is resistant against water, shock, vibration, and temperatures ranging from -13 to 185°F.

A: Hi Ayaan, If you are shooting with the Black Magic Pocket Cinema 4K you will want to use our V90 card not the V60 card. Both of those cards are available at B&H. Let us know if you have any other questions we can answer. - ProGrade Digital

Q: 9. How many hours of 4k video can you shoot with this?

A: It depends on the camera, and the bit rate, frame rate, codec used. It could vary wildly depending on all of these factors. For example the 5d mark iv has one of the least efficient codecs and in 4k 30fps it only records 34 minutes in 128gb.
