About Hardware OPPO A15s eMMC 5.1

OPPO A15s eMMC 5.1 is the eMMC (embedded MultiMediaCard) version 5.1-based internal storage chip used in the OPPO A15s smartphone. The eMMC 5.1 technology is a significant upgrade from the previous generation, delivering faster read/write speeds, better power efficiency, and improved performance in data input/output management. While not as fast as the more modern UFS (Universal Flash Storage) technology, eMMC 5.1 remains a reliable storage standard for entry-level to mid-range smartphones.

This storage is designed to provide a seamless user experience, from opening apps, saving files, recording videos, to managing Android system data. It also plays an important role in operating system stability, lightweight multitasking, and response time when the device starts up or switches between apps.

The tests were conducted on an OPPO A15s device with MediaTek Helio P35 (MT6765) specifications, 4GB RAM, and 64GB internal storage, running on Android 10 operating system with ColorOS 7.2 interface. The test was conducted when the device had been in use for approximately two years, so the performance results may be slightly affected by NAND Flash performance degradation over time (wear leveling).

In a benchmark using the Cross Platform Disk Test (Mobile), the eMMC 5.1 on the OPPO A15s recorded a read speed of 145.27 MB/s and a write speed of 50.09 MB/s. This indicates that the storage performance is still solid enough for daily needs such as opening social media, streaming videos, accessing galleries, and saving files from third-party applications.

Overall, the eMMC 5.1 on the OPPO A15s is a well-balanced internal storage solution between price, efficiency, and performance, perfect for users who need a smartphone with responsive capabilities while remaining power efficient. For casual users, this performance is more than enough to run most popular Android apps without a hitch.

Device test (testbed):

Device: OPPO A15s
CPU: MediaTek MT6765 Helio P35
RAM: 4GB
Storage: 64GB
OS: Android 10, ColorOS 7.2

* This hardware test was conducted after the device was approximately 2 years old, there may be some performance degradation.

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.
