About Hardware SanDisk Ultra MicroSDHC 8GB
The SanDisk Ultra MicroSDHC 8GB is an 8GB memory card that supports Class 10 UHS-I speeds, designed for everyday storage purposes such as storing photos, videos, or light files on mobile devices such as smartphones, digital cameras, or tablets. Although the capacity is relatively small by today's standards, this card is still useful for basic purposes or as backup media.
With a read speed of up to 80MB/s theoretically, this microSD card is enough to support HD video playback and light data transfer. However, the limited capacity makes it less suitable for storing large amounts of apps or multimedia files.
The test was conducted using a Lenovo IdeaPad Slim 3i 14ITL6 equipped with 12GB DDR4 Dual Channel RAM and Windows 11 22H2 operating system. The card was tested through a VENTION USB 3.0 Card Reader with a GL3224 controller connected to a USB 3.1 Gen 1 port.
Based on the test results with CrystalDiskMark, the read speed obtained was 46.70 MB/s and the write speed was 11.73 MB/s. Meanwhile, in the Cross Platform Disk Test, the read speed reached 40.87 MB/s and the write speed 8.02 MB/s. Although it does not reach the theoretical maximum performance, these results are quite representative for light daily use.

Device: Lenovo IdeaPad Slim 3i 14ITL6
RAM: 12GB DDR4 3200MHz Dual Channel (8+4)
OS: Windows 11 22H2
USB: USB 3.1 Gen 1

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
