About Hardware SK hynix H9TQ27ADFTMC
SK hynix H9TQ27ADFTMC is an eMMC (embedded MultiMediaCard) based storage chip designed for mobile devices and embedded systems. With NAND Flash technology, it offers an efficient and power-efficient internal storage solution for devices with light to medium computing needs. It has become a common choice in entry-level smartphones, tablets, and Internet of Things (IoT) devices, thanks to its combination of sufficient capacity, high endurance, and long-term stable performance.
As an internal chip, the H9TQ27ADFTMC comes in a small yet reliable package, combining the controller and flash memory in a single unit for easy integration in consumer devices. One of the main advantages of eMMC storage like this is low power consumption and better data access latency compared to traditional SD card-based storage.
The test was conducted on an OPPO A5s device, a smartphone with a MediaTek Helio P35 (MT6765) processor, 3GB of RAM, and 32GB of internal storage. The operating system used was Android 8 with the ColorOS 5.2 interface. The test was conducted after the device had been in use for more than four years, so performance results may have decreased due to NAND Flash degradation over time.
In testing using the Cross Platform Disk Test (Mobile), the read speed of 114.31 MB/s and write speed of 13.07 MB/s were obtained. These results show that despite its age, the eMMC's read performance is still quite good for activities such as opening applications, loading the system, and streaming light content.
As a first-in-class internal storage solution, the SK hynix H9TQ27ADFTMC is suitable for devices that require fixed (non-removable) internal storage capacity with high efficiency, low cost, and sufficient endurance for daily use. Although its write speed is not as fast as more modern UFS technology, eMMC remains a popular choice due to its stability and ease of integration in many low- to mid-end devices.
Device: OPPO A5s
CPU: MediaTek MT6765 Helio P35
RAM: 3GB
Storage: 32GB
OS: Android 8, ColorOS 5.2
* The test was conducted after the device was approximately 4 years old, perhaps the performance has decreased

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)
