Exascend 64GB Essential UHS-II SDXC Memory Card EX64GSDU2-S

Optimized for demanding uses in professional photography and cinematography, the 64GB Essential UHS-II SDXC Memory Card from Exascend lets you quickly record and offload footage, even when working with extreme bitrates, to help ensure there are no dropped frames. This card features a storage capacity of 64GB and utilizes the UHS-II bus to deliver maximum sequential read speeds of 300 MB/s and maximum sequential write speeds of 260 MB/s. Thanks to its V90 speed class rating, minimum write speeds are guaranteed not to drop below 90 MB/s.

To help facilitate card usage in almost any environment, as well as keep your content safe, Exascend has built the Essential series with a rugged design that can withstand water, dust, impact, X-rays, magnets, and temperatures ranging from -13 to 185°F. To help protect your data from being accidentally deleted, there is a built-in write-protect switch.

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, which support 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.
