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 Lexar JumpDrive V100 32GB

The Lexar JumpDrive V100 32GB is a portable storage solution designed to provide an optimal combination of speed, reliability and affordability. With a 32GB capacity, this flash drive is perfect for storing important documents, photos, videos, and lightweight presentation files and installers, making it an ideal choice for students, office employees, and casual users.

Using a USB 3.0 interface, the Lexar V100 is able to provide better read and write speeds than traditional USB 2.0 flash drives. While it still supports backward compatibility with USB 2.0 ports, using it on a USB 3.1 Gen 1 port will maximize its performance. Its compact and lightweight design makes it easy to carry around, while its cap cover helps keep the USB connector protected from dust and damage.

This flash drive speed test was conducted using a Lenovo IdeaPad Slim 3i 14ITL6 device, powered by an Intel Core i5-1135G7 processor, supported with 12GB DDR4 dual channel RAM, and running Windows 11 version 22H2 operating system. The combination of these specifications provides a stable and representative testing environment to assess the actual performance of the flash drive under test.

In tests using the CrystalDiskMark application, the flash drive was able to record read speeds of up to 143.53 MB/s, while write speeds reached 34.33 MB/s. These results reflect quite good performance for daily use such as moving documents, images, or medium-sized media files.

Meanwhile, through additional testing using ATTO Disk Benchmark with a block size of 64MB, the flash drive showed a read speed of 140.66 MB/s and a write speed of 25.04 MB/s. Slightly lower write performance in ATTO compared to CrystalDiskMark is common, as the test methods used by each benchmark can produce varying results depending on the type of data and block size used.

Overall, this flash drive offers a fairly high read performance for its class, although the write speed is moderate. For users looking for a portable storage solution for daily data transfer purposes, this flash drive remains reliable with consistent performance across various scenarios.

The read speed of close to 140MB/s shows that this flash drive is responsive enough for activities such as opening large files or playing videos directly from USB. However, the lower write speed (below 40MB/s) reflects the reasonable limitations of economy-class flash drives without DRAM cache.

Technically, the Lexar V100 uses the PF619-32AR NAND chip and ZC3281 controller, a common configuration for low-cost and power-efficient flash drives. Although TBW (Total Bytes Written) and DRAM cache specifications are not available, Lexar remains a trusted brand in the digital storage world, with a good reputation for manufacturing quality and system compatibility.

With a simple design, decent read speed, and competitive price, the Lexar JumpDrive V100 32GB is one of the best choices for users who need a cheap and reliable USB 3.0 flash drive for daily use.

Device test (testbed):

Device: Lenovo IdeaPad Slim 3i 14ITL6
CPU: i5 1135G7
USB: USB 3.1 Gen 1
RAM: 12GB DDR4 3200MHz Dual Channel (8+4)
OS: Windows 11 22H2
