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 HGST HTS545050A7E680

The HGST HTS545050A7E680 is a 500GB hard disk drive (HDD) designed for storage needs in laptops, external enclosures, and other mobile devices. With a 2.5-inch form factor, 5400 RPM rotation speed, and 3.0Gbps SATA II interface, this HDD offers an ideal blend of capacity, power efficiency, and stable and quiet performance for everyday computing needs.

Based on the Travelstar Z5K500 family, this HDD uses 1 platter and 2 heads, which structurally supports reasonably efficient performance without generating excess heat or noise. The 8MB buffer cache provides a speed boost in short data processing, which is especially useful for light activities such as opening document files, playing videos, and storing business application data.

In tests using a USB 3.0 HDD enclosure connected to a Lenovo IdeaPad Slim 3i 14ITL6 laptop (with Intel Core i5-1135G7 processor and 12GB DDR4 dual-channel RAM), the drive recorded CrystalDiskMark scores of 108.05 MB/s read and 104.88 MB/s write speeds. Meanwhile, the ATTO Disk Benchmark (64M) test showed read performance of 102.40 MB/s and write performance of 101.45 MB/s - relatively good results for a 5400 RPM HDD in an external configuration.

While not an SSD, the HGST HTS545050A7E680 still offers high reliability and low power consumption, making it a suitable solution for users who need additional storage or an affordable replacement for an internal HDD while still prioritizing long-term stability. In addition, HGST's shock resistance feature provides extra protection against minor physical impacts that often occur on mobile devices.

Overall, the HGST HTS545050A7E680 is a great choice for laptop users, light content creators or business users who require medium capacity, low power consumption and reliable performance in a portable or internal drive.
