Samsung's Bar series USB flash drive shell is a high-quality metal shell with light champagne color, which has a metallic texture, ensures the durability of use and creates an ergonomic use experience. The streamlined spherical end allows you to easily plug in and out the U disk, and the feel in the test is much easier than that of many flat products. This is really a well-thought-out design. This ring can also be used as a key ring to prevent loss. Now this USB flash drive has been sold in JD.COM, and the price of the 32G version in Bian Xiao's hand is 99 yuan. Interested friends can click to view the details.
It is 40mm long and weighs less than 9g. The standard interface is designed for PC data transmission. The three capacity versions of 16G, 32G and 64G are all normal, but it is a little pity that there is no version of 128G. This small series got the 32G version, and you can see that the lettering on the back of the U disk is very good.
Equipped with the mainstream USB3.0 interface, the interface is naturally a touch of fresh blue. NAND flash memory technology and metal shell make it have a series of protective functions such as waterproof, shockproof, antimagnetic, extreme temperature protection and X-ray protection. Out of confidence in production quality, Samsung provided a five-year warranty, which is a conscience.
Performance test of genuine Samsung BAR disk
In order to get accurate test results, we choose ASUS FX-Plus notebook with magnesium SSD/ high-current USB3.0 interface as the test platform. The system is an officially upgraded Windows 10 home version, which is more in line with the daily use environment.
Let's take a look at its specific chip information first. Because it is a new product, the software does not recognize the specific brand information of the USB flash drive, but we can see that its main control chip comes from SM3267AB in Rong Hui. This kind of main control chip is common in all kinds of high-end USB flash drives. Flash memory chips naturally come from Samsung's original factory.
ATTO disk benchmark is a simple and easy-to-use software for detecting disk transfer rate, which can be used to detect the read-write rate of mobile disks such as hard disk, U disk and memory card. The software uses data test packages of different sizes. The data packet has been tested at 0.5K, 1.0K, 2.0K and 8 192.0KB respectively. After the test, the data is represented in the form of histogram. It can well explain the influence of different file size ratios on disk reading and writing speed. Samsung Bar has achieved a reading speed of about 150M and a writing speed of about 100M, and its comprehensive performance is very strong.
CrystalDiskMark is a testing tool for testing computer hard disk. The simple and easy-to-operate interface allows you to test your storage device at any time. You can choose the size of the storage device and the number of tests, and you can also test the reading and writing speed. The test results show that the results are not much different from those of ATTO disk benchmark test, which shows that its speed is still very stable.
HDTune is a compact and easy-to-use hard disk detection tool software, and HD Tune Pro is also a mobile hard disk detection tool. The main functions are hard disk transmission rate detection, health status detection, temperature detection and disk scanning. In addition, it can also detect the firmware version, serial number, capacity, cache size and current Ultra DMA mode of the hard disk. This is mainly used to test the access stability of the U disk, and the bar score is also very stable. We have reason to believe that this is due to NAND memory cells.
Summary:
Samsung's achievements in the field of solid-state storage are obvious to all, and this brand-new U disk production line has a good performance in external design, internal chip and main control, showing the spirit of the king. Five-year warranty plus five-fold guarantee is also quite sincere and conscientious. The dual advantages of technology and design make this USB flash drive an excellent productivity tool for office workers.
