About Hardware OPPO A15s eMMC 5.1

OPPO A15s eMMC 5.1 is the eMMC (embedded MultiMediaCard) version 5.1-based internal storage chip used in the OPPO A15s smartphone. The eMMC 5.1 technology is a significant upgrade from the previous generation, delivering faster read/write speeds, better power efficiency, and improved performance in data input/output management. While not as fast as the more modern UFS (Universal Flash Storage) technology, eMMC 5.1 remains a reliable storage standard for entry-level to mid-range smartphones.

This storage is designed to provide a seamless user experience, from opening apps, saving files, recording videos, to managing Android system data. It also plays an important role in operating system stability, lightweight multitasking, and response time when the device starts up or switches between apps.

The tests were conducted on an OPPO A15s device with MediaTek Helio P35 (MT6765) specifications, 4GB RAM, and 64GB internal storage, running on Android 10 operating system with ColorOS 7.2 interface. The test was conducted when the device had been in use for approximately two years, so the performance results may be slightly affected by NAND Flash performance degradation over time (wear leveling).

In a benchmark using the Cross Platform Disk Test (Mobile), the eMMC 5.1 on the OPPO A15s recorded a read speed of 145.27 MB/s and a write speed of 50.09 MB/s. This indicates that the storage performance is still solid enough for daily needs such as opening social media, streaming videos, accessing galleries, and saving files from third-party applications.

Overall, the eMMC 5.1 on the OPPO A15s is a well-balanced internal storage solution between price, efficiency, and performance, perfect for users who need a smartphone with responsive capabilities while remaining power efficient. For casual users, this performance is more than enough to run most popular Android apps without a hitch.
