Designed for photographers and videographers, the 128GB Advantage UHS-I SDXC Memory Card from Delkin Devices features a storage capacity of 128GB and takes advantage of the UHS-I bus to support maximum read speeds of 100 MB/s and maximum write speeds of 80 MB/s. This card has also been designed with the V30 Video Speed Class rating, which guarantees minimum write speeds of at least 30 MB/s, allowing the card to be optimized for 4K and Full HD 1080p video capture, as well as raw, JPEG, rapid-fire burst photos in DSLRs and camcorders. While this card has been designed for cameras that are UHS-I / V30 compatible, it may be used in devices that do not support UHS-I / V30. However, bear in mind that this card will then default to your device's speed class and bus rating, such as V10, V6, or Class 10. Built for extreme conditions, Delkin's 128GB Select UHS-I SDXC Memory Card is protected against water, shock, and x-rays, and also features built-in error correction and wear leveling. A built-in write protect switch helps to safeguard your content from being erased. Included is a protective storage case.
