Designed for 8K, 4K, Full HD, and 3D video, as well as raw and continuous burst photography in DSLRs and mirrorless cameras, the 64GB Steel UHS-II SDXC Memory Card Bundle from Hoodman features a storage capacity of 64GB and takes advantage of the UHS-II bus to support sustained read speeds of 260 MB/s and sustained write speeds of 100 MB/s. This card has also been designed with the V60 Video Speed Class rating, which guarantees minimum write speeds of 60 MB/s. This card has also been ruggedized to help protect it from damage and outdoor elements. 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 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.This bundle includes a Steel SD/microSD UHS-II Card Reader from Hoodman. This card reader natively supports SD, SDHC, and SDXC cards, as well as microSD, microSD, and microSDXC cards at speeds up to 5 Gb/s, thanks to the USB 3.1 Gen 1 standard. This reader connects to your host system using its USB Type-A interface, or use the included USB Type-A to Type-C adapter for use with USB Type-C hosts.
