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.

Device test (testbed):

Device: OPPO A15s
CPU: MediaTek MT6765 Helio P35
RAM: 4GB
Storage: 64GB
OS: Android 10, ColorOS 7.2

* This hardware test was conducted after the device was approximately 2 years old, there may be some performance degradation.

With a capacity of 64GB, this microSD is suitable for storing large collections of photos, Full HD videos, music and applications.

Using UHS-I Class 10 technology, the Kingston Canvas Select Plus offers read speeds of up to 100MB/s, providing a fast and stable data transfer experience, and supports high-quality video recording without lag. The card is also designed with a high level of resistance to water, shock, vibration and extreme temperatures, making it an ideal choice for both everyday use and professional scenarios.

The test was conducted on a Lenovo IdeaPad Slim 3i 14ITL6 device, with Intel Core i5-1135G7, NVIDIA MX350, 12GB DDR4 3200MHz RAM, 512GB NVMe SSD, and Windows 11 Home 23H2 operating system. The card was tested using a Lexar RW450 rev B card reader (GL3231S Controller) via a USB 3.1 Gen 1 port, in brand new condition, with no files (0% usage), default file system exFAT, and Quick Removal policy in Device Manager.

In our performance testing, the 64GB Kingston Canvas Select Plus performed quite well for the mainstream microSD class. Through testing using CrystalDiskMark, the card recorded a read speed of 89.52 MB/s and a write speed of 20.75 MB/s. Similar results were also seen in the Cross Platform Disk Test, with read speeds of 89.56 MB/s and write speeds of 15.71 MB/s. Meanwhile, the test using AS-SSD recorded a read speed of 87.60 MB/s and a write speed of 16.22 MB/s. Overall, this performance reflects the card's ability to efficiently handle common tasks such as file transfer, video recording, and light application usage.

These results prove that the card is capable of handling common needs such as Full HD video recording, large application installation, and data backup, with good efficiency and reliability.

Overall, the Kingston Canvas Select Plus MicroSDXC 64GB is a solid and affordable storage solution for users who prioritize stable performance, high endurance, and broad compatibility across digital devices. A great choice for everyday needs as well as intense multimedia activities.
