The leap of NAND flash memory in process, process and production capacity continues to promote the performance of memory products, and also profoundly affects the product form and industry trend. From the built-in PCIe protocol SSD, the peak performance is over 7000MB/s, and the small external mobile SSD can reach 1050MB/s in an instant.
Such performance growth far exceeds consumer performance cognition, to know that a few years ago, the performance of various types of storage was still peaked at 550MB/s of SATA interface.

Samsung 2022 Type-C U disk
The protagonist we will review today, Samsung 2022 Type-C U disk, is also based on NAND flash memory as the core medium, a storage product that has revolutionized changes in performance, form and interface.
The ratings we give are minimalism, extreme and extreme speed, speaking separately
In terms of appearance design, the streamlined shape will implement the minimalist style to the extreme
In terms of size and style, the extreme slim and compact, the size of the nail cover, delicate and stylish
In terms of performance, it focuses on the Type-C interface, supports usb 3.1 protocol, and reads up to more than 400MB/s
01 Minimalist design Extreme dimensions
In terms of appearance design, it continues the design gene of the Samsung U disk family, still with streamlined design as the main style, separate cap design, U disk cap damping is very low, can easily achieve opening and closing; the processing process is superior, making the gap at the product connection extremely small and the integrity is very strong.
Streamlined design
In terms of color, the aurora blue color, which is very popular in the science and technology circle in recent years, is adopted, and the blue coating wraps the fuselage and cap; the front and back sides are printed with the brand LOGO, storage capacity and storage protocol information respectively, eliminating redundancy.
Detach the design
In terms of size, it implements the concept of minimalism, almost comparable to the size of a fingernail, far smaller than the size of a conventional U disk, and the weight of only 3.4g also verifies the exquisite compactness of this USB stick in design.
Slim size
In terms of interface, the Samsung 2022 Type-C U disk for Type-C storage devices has designed a Type-C interface that supports the USB3.1 protocol, which is backward compatible with mainstream transmission protocols such as USB3.0/2.0; at the same time, based on the full popularity of the Type-C interface at this stage, the Samsung 2022 Type-C U disk can be directly inserted into the mainstream notebooks, mobile phones, tablets and other related devices, efficient and flexible.
Compatible with devices such as mobile phones, tablets and laptops
As for performance, Samsung 2022 Type-C U disk built-in Samsung original NAND particles, as well as self-developed main control chip, the maximum continuous reading speed reached 400MB/s, and it only takes 11 seconds to transfer about 4GB of material files.
Multiple protections
Of course, as a NAND-based media flash drive, Samsung 2022 Type-C U disk also has multiple protection design, waterproof, impactproof, magnetic, high temperature and radiation resistance and other safety design, while 5 years of limited warranty, no need to worry about quality and cause data storage problems.
02 Theoretical performance Extremely fast performance
After a brief introduction to the design and size style, enter the performance test session. In terms of performance testing, we will evaluate performance from two dimensions: theoretical performance test and actual performance test.
The theoretical performance part, based on the characteristics of the U disk product, mainly considers the continuous performance and comprehensive performance.
In terms of continuous performance, the two softwares of CrystalDiskMark and ATTO are used for comparative testing.
The biggest of these two software is the ability to customize the test load, queue depth, and threading according to the product positioning, and at the same time, it can quickly and intuitively present the results, which is one of the best choices for us to understand the performance of memory.
CrystalDiskMark testing
ATTO testing
Combined with the test data, in terms of maximum continuous performance, the maximum continuous reading speed of Samsung's 2022 Type-C U disk reached 420MB/s, while the maximum continuous write speed reached 115MB/s, compared with traditional U disk products, it has an exaggerated performance improvement in reading performance.
As for the performance of different data blocks, starting from the mainstream data block of 128KB to the larger data block of 64MB, the Samsung 2022 Type-C U disk has maintained a maximum continuous read of 400MB/s and a maximum continuous write of about 110MB/s, reflecting the stable and high-performance performance of the USB disk in different block scenarios.
In terms of comprehensive performance testing, the new version of PC Mark10 Professional Edition built-in data disk performance test, the test can simulate the normal system operation scenario, through the internal calculation of the program, the disk as an external data disk, the real system simulation, record the performance in the form of numerical value, has considerable reference value.
PC Mark10 tested
Under the test, there are three values worth referencing, the total score, Samsung 2022 Type-C U disk got 393 points, showing the performance advantages of the U disk in the integrated system environment, in the more critical hard disk bandwidth and average access time dimensions, Samsung 2022 Type-C U disk also with the new master and new particles in the process process and IO queue advantages, has achieved quite good results.
03 Actual performance data transfer max
Theoretical performance test, although important, can be actual performance, can more intuitively reflect the real performance of the U disk, more reference significance.
In the actual test, we will simulate the whole process of the user's daily material copy, first transfer the test file stored in the computer to the U disk, record the time and transfer the whole process; and then transmit the test file in the U disk back to the computer, and record the time and transfer process again.
To avoid test errors, we perform on the same computer, the same system, and at the same room temperature.
Transfer the computer to a USB stick
In the simulation test of computer transmission to U disk, more test of U disk writing performance, through the data performance can be seen, the basic and theoretical performance is consistent, the maximum continuous write maintenance at about 110MB /s, the transmission of about 10GB of test materials, about 90 seconds.
Transfer a USB flash drive to your computer
In the more common U disk data copy to the computer application scenario, Samsung 2022 Type-C U disk performance is more strong, from the data point of view, almost the whole process is maintained between 390-400MB / s, to complete about 10GB of data copy takes only about 25 seconds, compared to the conventional U disk 100MB / s level, the USB disk can significantly improve the user's data transmission efficiency, is a must-have quality product for business people.
04 Type-C has arrived
Minimalist appearance style, extreme size design, extreme performance performance, Samsung's new U disk born for Type-C, still maintain Samsung's product strength of excellence, meticulous craftsmanship, and as a storage manufacturer for the future trend of judgment that Type-C will become the mainstream of the future.
Advance layout, performance first, at the time when the removable storage interface is about to fully "C" the port, Samsung 2022 Type-C U disk has once again become the forerunner of Samsung storage leading the industry.
It can be expected that in the next removable storage market, type-C as the core of the flash disk, will become the new mainstream, and gradually compete with the former top-stream USB-A.
This is the revolution of products, but also the revolution of technology, but also the revolution of demand.
