About Hardware Samsung KMRX10014M

OPPO F1s eMMC 5.1 (Samsung KMRX10014M) is an internal storage chip made by Samsung that is used in the OPPO F1s smartphone. Relying on eMMC 5.1 technology, this chip offers increased data transfer speeds compared to the previous generation (eMMC 5.0), providing a smoother user experience, especially when it comes to opening apps, saving files, and running the Android operating system responsively.

Although not comparable to UFS (Universal Flash Storage) in terms of performance, eMMC 5.1 remains an economical storage solution for mid-range devices like the OPPO F1s. The technology is reliable enough to handle everyday activities such as opening social media, recording videos, taking photos, and storing documents and apps.

The test was conducted on an OPPO F1s device with MediaTek MT6750 specifications, 4GB of RAM, and 32GB of internal storage, running on the Android 6 operating system. The internal storage on the OPPO F1s uses the Samsung KMRX10014M chip, which is an early generation eMMC 5.1 with relatively high performance for the standards of its release time.

Interestingly, despite the device being over 7 years old, testing using the Cross Platform Disk Test (Mobile) showed read speeds of 286.5 MB/s and write speeds of 78.7 MB/s. These figures are impressive for an eMMC chip that has gone through a long usage cycle, and indicate that the Samsung KMRX10014M has good NAND Flash endurance.

Overall, the eMMC 5.1 on the OPPO F1s offers an ideal combination of power efficiency, moderately high performance, and low manufacturing costs. This makes it a very suitable solution for devices with standard to mid-range requirements, especially when first released. While eMMC performance may degrade with age, these benchmark results show that the chip is still capable of performing quite well even after many years.

Device test (testbed):

Device: OPPO F1s
CPU: MediaTek MT6750
RAM: 4GB
Storage: 32GB
OS: Android 6

* This test was conducted after the device was approximately 7 years old, which is likely to have degraded the performance of eMMC.

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.
