the PRIME UHS-II SDXC Memory Card from Delkin Devices has a storage capacity and a UHS-II bus to support maximum read speeds of 280 MB/s and maximum write speeds of 150 MB/s. It has a V60 Video Speed Class rating, which guarantees minimum write speeds of at least 60 MB/s, optimal for cinema-quality 8K, 4K, and Full HD 1080p video capture, as well as raw photos and rapid-fire bursts in DSLRs and camcorders. It also supports advanced modes that require the simultaneous capture and storage of multiple files, including raw + JPEG captures, multiple video streams created by 360° cameras, plus still, GPS data, and time-lapse. 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 / V60 compatible, it may also 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 guarantees minimum write speeds of 10 MB/s. Built for extreme conditions, Delkin's PRIME UHS-II SDXC Memory Card is protected against water, shock, and x-rays. It also features built-in error correction and wear leveling and has a built-in write protect switch to safeguard your content from being erased. It comes with a protective storage case.
