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. *A1 compliance applies only to 128GB capacity cards. |
Show the transfer capabilitiesTranscend's microSDXC/SDHC 300S memory cards meet both the UHS Speed Class 3 (U3) and the UHS Video Speed Class 30 (V30) standards for 4K Ultra HD video recordings, with read/write speeds of up to 95MB/s and 45MB/s respectively. *U3 and V30 compliance applies only to 128GB capacity cards. |

|---|---|---|---|
UHS Bus InterfaceUHS-I provides faster bus speed using just one row of pins, while UHS-II uses two lanes for even faster data transfer via two rows of pins. The symbol "I" means UHS-I, and "II" means UHS-II. Please make sure your device supports the same standard to benefit from the increased speeds. |
UHS Speed ClassUHS Speed Class includes UHS Speed Class 1 (U1) and UHS Speed Class 3 (U3). UHS Speed Class 1 supports a minimum 10MB/s write speed, whereas UHS Speed Class 3 supports at least 30MB/s write speed. |
Video Speed ClassVideo Speed Class is defined to answer a demand for high resolution and high quality 4K8K video recording. V60 (60 MB/s) and V90 (90 MB/s) can support 8K resolution, while V6, V10 and V30 capture high-definition and 4K resolution and ensure minimum sequential write speeds of 6 MB/s, 10 MB/s and 30 MB/s respectively. |
Application Performance ClassApplication Performance Class assures minimum random and sequential performance speeds to run and store smartphone apps. Application Performance Class 1 (A1) delivers minimum random read of 1,500 IOPS and random write of 500 IOPS. Application Performance Class 2 (A2) delivers minimum random read of 4,000 IOPS and random write of 2,000 IOPS. |
