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 Maestromemory MicroSDXC 128GB
MaestroMemory MicroSDXC 128GB is an affordable yet reliable external storage solution, designed for use in various devices such as smartphones, tablets, digital cameras, and laptops. Supported by UHS-I and Class 10 technology, this memory card offers high data transfer speeds to support multimedia needs such as video recording, storing high-resolution photos, and running mobile applications without any significant obstacles.
The large capacity of 128GB provides ample space to store important files such as work documents, music collections, and video content. In addition, MaestroMemory also emphasizes power efficiency and resistance to various environmental conditions, such as high and low temperatures, making it suitable for long-term use in various situations. The card is compatible with the exFAT file system which is the storage standard for modern devices, maximizing space usage and compatibility.
The test was conducted using a Lenovo IdeaPad Slim 3i 14ITL6 equipped with an Intel Core i5-1135G7 processor, NVIDIA MX350 GPU, and 12GB RAM, with Windows 11 Home 23H2 operating system. The tests were conducted through the USB 3.1 Gen 1 port using a VENTION USB 3.0 card reader with GL3224 controller, in a freshly opened card condition, with no files, and the default “Quick Removal” policy from Device Manager.
The benchmark results show quite competitive performance in its class. In tests using CrystalDiskMark, the 128GB MaestroMemory recorded read speeds of 93.41 MB/s and write speeds of 55.99 MB/s. Further testing with ATTO Disk Benchmark (64M) showed read speeds of 92.09 MB/s and write speeds of 45.47 MB/s, while Cross Platform Disk Test recorded speeds of 91.13 MB/s for read and 47.95 MB/s for write. These figures show that this microSD card is capable of meeting daily needs such as Full HD video recording, installation of large applications, or transferring large amounts of data.
However, it should be noted that we did not find any official information about the manufacturer of MaestroMemory, including the company's website or technical documentation that is usually found on reputable brands. We found this microSD card widely sold in the Indonesian marketplace, and based on discussions, there is speculation that MaestroMemory is a sub-brand of V-GeN Indonesia, although this claim has yet to be officially verified. If you try to search for MaestroMemory on international marketplaces, you will most likely not find it.
For additional validation, we also conducted a capacity integrity test using H2testw, and the results showed that the MaestroMemory 128GB microSD passed the test, with the correct capacity and no damaged areas or fake storage detected.
Overall, the MaestroMemory MicroSDXC 128GB is an attractive option for users looking for a large capacity memory card at a competitive price, as long as it is used in accordance with its class and segmentation. As a wise move, users are advised to always perform authenticity checks and post-purchase performance tests.
