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.

About Hardware Samsung EVO Plus 64GB

Samsung EVO Plus 64GB microSDXC is a high-performance memory card designed to meet the modern storage needs of devices such as smartphones, tablets, action cams, drones, and gaming consoles like Nintendo Switch. With a speed rating of UHS-I, Class 10, U1/V10, the card is capable of achieving read speeds of up to 130MB/s, making it an ideal choice for recording Full HD videos, storing high-resolution photos, and running mobile apps or games smoothly.

Using Samsung's advanced NAND flash technology, the EVO Plus delivers reliable performance and high durability in long-term use. The card has also passed tests to withstand extreme conditions-water resistance, heat and cold resistance, X-ray resistance, and magnetic field resistance, making it perfect for outdoor photographers, travelers, and other active users who are often in extreme environments.

Samsung also includes an SD adapter in the sales package, allowing users to utilize this card in DSLR cameras, camcorders, or laptops with standard SD slots. The exFAT file system support by default makes it compatible with a wide range of operating systems, including Windows, macOS, Android, and others.

This card was tested using a Lenovo IdeaPad Slim 3i 14ITL6, which features an Intel Core i5-1135G7, NVIDIA MX350 GPU, 12GB DDR4 3200MHz RAM, and 512GB NVMe SSD internal storage. The device was tested at a room temperature of 30°C based on the DHT11 sensor, and using a Lexar RW450 rev B card reader with a GL3231S controller via a USB 3.1 Gen 1 port. The test was conducted under new card conditions, with no files, and using the default settings in Device Manager (Quick Removal on).

Benchmark results using CrystalDiskMark show a very impressive performance, with a read speed of 124.57 MB/s and a write speed of 34.55 MB/s. These figures reflect the high speed and stable performance offered by the EVO Plus 64GB, making it very competitive in its class.

Overall, the Samsung EVO Plus 64GB microSDXC is a fast, reliable and durable storage solution. Suitable for a variety of purposes-from storing multimedia content to expanding the storage capacity of mobile devices-the card delivers optimal performance with the trusted quality of the Samsung brand. For users who need a fast microSD card with high durability and broad support for modern devices, EVO Plus is a highly recommended choice.
