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 Hitachi HTS547550A9E384

The Hitachi HTS547550A9E384 is a 500GB 2.5-inch hard disk drive (HDD) designed for laptops, notebooks and portable devices. This HDD belongs to the Travelstar 5K750 line, which is known for its balance between performance, power efficiency and reliability.

Using a 3.0Gbps SATA-II interface and a rotation speed of 5400 RPM, the drive offers good enough performance for daily computing activities such as document storage, multimedia playback, and light operating system installation. Equipped with an 8MB buffer cache, this hard drive provides a stable usage experience, though not as fast as a 7200 RPM HDD.

The Hitachi HTS547550A9E384 comes with a 500GB capacity, enough to store thousands of documents, photos, and multimedia files on a single device. This hard disk uses a 2.5-inch form factor with a SATA-II (3.0Gbps) interface, which is still widely used in older generation laptops. The spinning speed is 5400 RPM, which is not as fast as a 7200 RPM HDD, but it is more power-efficient and quieter in operation.

Underneath the body, this HDD has an 8MB buffer (cache), and consists of two platters and three data-reading heads. The drive is part of the Travelstar 5K750 line, which is known for its durability and efficiency for everyday use, especially in portable devices or laptops with limited power.

To determine its performance, the drive was tested using an HP 1000 1b05au laptop powered by an AMD E1-1200 processor, with a 2x2GB DDR3 1066MHz RAM configuration in single channel mode due to limited dual channel support on the CPU. The drive is mounted via HDD Caddy on the DVD slot and runs Windows 7 operating system.

In tests using CrystalDiskMark, the HDD recorded a read speed of 88.66 MB/s and a write speed of 88.06 MB/s. These results reflect the typical performance of a 5400 RPM HDD with a SATA-II interface, sufficient for standard use such as light booting, file storage, and basic applications.

That's consistent performance with 5400RPM HDDs of this generation and interface. While these drives don't rival SSDs in terms of speed, they are still an ideal power-saving storage solution for devices with battery limitations or legacy devices that still rely on mechanical storage.

Device test (testbed):

Device: HP 1000 1b05au (using HDD Caddy on DVD Slot)
Specs: 
CPU: AMD E1-1200
OS: Windows 7
RAM: 2x2GB Single Channel 2 DIMM 1066MHz (Does not support dual channel due to limitations of the CPU, currently running single channel mode and 1066MHz)
