Transcend - 10x 256GB 300S UHS-I microSDXC Memory Card with SD Adapter

Transcend 256GB 300S UHS-I microSDXC Memory Card with SD Adapter-- Upgrade the storage and performance of your mobile device using the 256GB 300S UHS-I microSDXC Memory Card from Transcend. Designed to retrieve small pieces of data from random locations and improving app launch times, the 300S has a capacity of 256GB, supports the UHS-I bus, and features a speed class rating of V30, which guarantees minimum write speeds of 30 MB/s. If your device does not support the V30 standard, this card also supports the U3 standard, which likewise guarantees minimum write speeds of 30 MB/s. Read speeds are supported up to 95 MB/s and write speeds max out at 40 MB/s, also making this card suitable for Full HD, 3D, and 4K Video, plus raw and JPEG still photos and bursts.----While this card has been designed for cameras that are UHS-I / V30 / U3 compatible, it may be used in devices that do not support UHS-I / V30 / U3. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-I and U1, which support minimum write speeds of 10 MB/s, or Class 10, which also supports minimum write speeds of 10 MB/s.---- Features-- --A Good Fit for Mobile App Storage: It's common for users to install and run mobile apps from microSD cards in order to free up space on their device, making random read/write performance crucial.
