Transcend 300S 128GB UHS-I U3 A1 microSDXC/SDHC Memory Card
The cards meet the latest speed class standards and are characterized by very high read and write speeds. This makes them ideal for retrieving small amounts of data from any location and speeding up app launch times. It is common for users to install and run mobile applications on a memory card to free up internal storage on their mobile devices. For this use case, the random read and write performance of the card is crucial, which is why Transcend's microSDXC/SDHC 300S memory cards are excellent for storing mobile applications. The Application Performance Class was introduced to address this new trend. Transcend's microSDXC/SDHC 300S memory cards meet the new A1 standards, offering at least 1,500 IOPS for random reads and 500 IOPS for random writes, as well as a sustained sequential speed of at least 10 MB/s. With read and write speeds of up to 95 MB/s and 45 MB/s, Transcend's microSDXC/SDHC 300S memory cards also meet the UHS Speed Class 3 (U3) and UHS Video Speed Class 30 (V30) standards for 4K Ultra HD video recording. The microSDXC/SDHC 300S memory cards from Transcend have a capacity of up to 256 GB, allowing you to store even more digital files and apps. To deliver the best performance and stability, Transcend's microSD memory cards are tested under extreme conditions. They are temperature resistant, waterproof, shockproof, resistant to X-rays, and withstand static electricity.

I advise acquiring information first before giving a very low rating to this product.✅️ Now about this sucker, As soon as I inserted this microSD card into my phone, Android formatted it and created folders/directories for allocations. In terms of performance, I was surprised to find it faster than Lexar in certain capabilities. I just hope it lasts longer.
