microSDXC/SDHC 300S

Want to save space on your mobile device by running apps from a memory card? Transcend's

microSDXC/SDHC 300S cards are the right choice! Compliant with the latest speed class, the cards boast

excellent random read/write speed, perfect for retrieving small pieces of data from random locations and

speeding app launch time.

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 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 Class

The 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.
