Frequently asked questions
What video formats and resolutions can the Delkin PRIME 256GB UHS-II SDXC handle?
Thanks to its V60 Video Speed Class rating and guaranteed minimum sustained write speed of 60 MB/s, this card reliably handles cinema-quality 8K, 4K, and Full HD 1080p video at high frame rates, as well as advanced modes like simultaneous multi-stream 360° video and time-lapse recording.
Will this UHS-II card work in my older camera that only supports UHS-I?
Yes. While the card is optimized for UHS-II / V60 compatible devices, it is fully backward compatible with UHS-I devices. In a UHS-I host it will operate at U3 speeds (minimum 30 MB/s write), or U1 / Class 10 speeds (minimum 10 MB/s write) if U3 is not supported.
How fast can I transfer files from the Delkin PRIME 256GB card to my computer?
Using a UHS-II compatible card reader, you can offload data at read speeds of up to 280 MB/s, allowing you to quickly transfer large RAW files and 4K/8K video footage to your computer for faster post-production start times.
