About Hardware Seagate Momentus Thin ST320LT012-9WS14C

Seagate ST320LT012-9WS14C is a 320GB capacity hard disk drive (HDD) with a slim 2.5-inch form factor, ideal for laptops, notebooks and other portable systems. Designed using a SATA II (3Gbps) interface and a rotation speed of 5400 RPM, this HDD emphasizes power efficiency and quieter operation compared to higher-speed HDDs.

It uses 1 platter and 2 read/write heads, a common configuration for 320GB capacity, with light weight and low power consumption-suitable for mobile devices. Equipped with 16MB of buffer cache, its performance is sufficient for daily tasks such as saving documents, running light applications, or storing multimedia files.

This Seagate ST320LT012-9WS14C performance test was conducted using an HP 1000 1b05AU laptop that still relies on 4GB DDR3 Single Channel RAM with two DIMM slots. The operating system used during the test was Windows 7 64-bit, which is a typical environment for entry-level laptops in this era of HDD usage. The hardware combination reflects the real usage scenarios of older generation laptop users who still rely on mechanical hard disks as the primary storage medium.

In tests using CrystalDiskMark benchmark software, the Seagate ST320LT012-9WS14C hard disk recorded a fairly stable performance for the 5400 RPM HDD class. The sequential read speed reached 84.67 MB/s, while the sequential write speed stood at 83.84 MB/s. These results show that despite being an older generation HDD with modest specifications, its performance is still adequate for everyday light computing needs such as document storage and media playback.

Although its performance falls short of modern SSDs, the Seagate ST320LT012-9WS14C remains a reliable and cost-effective choice for users who need additional internal storage on older laptops, educational systems, or as external media (with a USB case). Its compact size and low power consumption also make it suitable for use in netbooks and other energy-efficient devices.

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.
