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.
