A good fit for mobile app storageIt’s common for users to install and run mobile apps from microSD cards in order to free device memory. Random read/write performance is thus crucial. Transcend’s microSDXC/SDHC 300S memory cards are a great fit for storing mobile apps. |
Introducing Application Performance ClassThe Application Performance Class was introduced to adapt this new trend. Transcend’s microSDXC/SDHC 300S memory cards meet the new A1 standards, delivering minimum random read of 1,500 IOPS and random write of 500 IOPS, and sustained sequential speeds of at least 10MB/s. Note: A1 compliance applies only to 128GB-256GB capacity cards. |
