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 SanDisk MicroSDHC 4GB

The SanDisk MicroSDHC 4GB Class 4 is a small yet powerful flash memory card designed specifically for devices such as cell phones, digital cameras, music players and other electronic devices that support the microSDHC format. With a capacity of 4GB, this card is enough to store hundreds of photos, dozens of songs, a few short videos, and lightweight applications - making it an ideal solution for everyday storage needs, especially on previous generation devices.

As a Class 4 memory card, this microSD guarantees a minimum write speed of 4MB/s, enough to handle standard activities such as recording SD videos, saving camera shots, or loading application data on mobile devices. SanDisk's proven flash memory technology makes this card resistant to shock, vibration, and light to moderate wear conditions, suitable for field use as well as for personal multimedia collections.

In performance testing using a VENTION USB 3.0 card reader (with GL3224 controller) connected to a Lenovo IdeaPad Slim 3i 14ITL6 laptop (Intel Core i5-1135G7 processor, 12GB DDR4 dual-channel RAM), the benchmark results showed consistent performance and within its class specifications. Through CrystalDiskMark, the card recorded read speeds of 19.50 MB/s and write speeds of 5.66 MB/s. Meanwhile, in the Cross Platform Disk Test, the read speed reached 18.71 MB/s with a write of 4.16 MB/s.

To ensure authenticity and actual capacity, verification was also done using H2testw, which showed satisfactory results: read speeds of 18.8 MB/s and write speeds of 4.51 MB/s with no sector errors or damage to its 4GB capacity. This confirms that this memory card is not only genuine, but also functional and stable to use for important data storage.

With stable performance, enough capacity for lightweight needs, and a very affordable price, the SanDisk MicroSDHC 4GB Class 4 remains a relevant choice for users who need simple, durable, and power-efficient additional storage, especially on older devices or as a portable backup medium.
