With the popularization of USB-Type C data interface, more and more mobile phones, laptops, , and desktops have begun to layout C-port matrix in large quantities. However, personal storage devices (U disk, mobile hard disk, etc.) that are slower to update are still mainly port A, which can easily cause many unnecessary troubles. For example, during the meeting, the prepared information is in the USB disk of port A, while the computer only port C can use, which will cause a very embarrassing situation. Therefore, in 2022, your USB flash drive and other devices should be updated to the C port form, which is not only more convenient in connection, but also has a considerable increase in speed. Today, a type-C USB3.1 USB drive MUF-256DA/APC for Samsung is a good choice.
This USB drive is Samsung's latest C-port shape device launched by USB3.1 Gen1. It adopts Samsung's international packaging style on the packaging, with the eye-catching "Type-C" and "256GB" logo.
The product information of the USB flash drive is printed on the back of the packaging, including some product safe use ranges, including:
Immerse in 3% sodium chloride brine at a depth of 1 meter deep for 72 hours
The bearing range during operation is 0°C to 60°C, and the bearing range during non-working is -10°C to 70°C.

A few warranty policies, capacity descriptions and other information.
Open the packaging, this USB flash drive gives me the first impression that it is very lightweight. It is made of solid synthetic materials, but it weighs only 3.4g, and it is as light as if nothing is left in my hand.
The size comparison between the USB flash drive and Samsung Note10+
The surface of the USB flash drive adopts a dark blue design and gives it a special aurora blue coating, which makes the USB flash drive have a "glitter" effect under the refraction of light, and a touch of metal texture. At the same time, the USB flash drive has a multi-faceted arc design and a streamlined body, making it look very exquisite. Whether it is for self-use or loaned to others, it can highlight the user's taste.
The USB flash cover and the body have lanyard holes, which makes it easier for users to tie them with thin ropes to avoid loss of the USB flash cover.
In the storage performance part of the USB disk itself, it uses Samsung's original NAND flash memory. It officially claims that it supports a maximum read speed of 400MB/s and a write speed of 100MB/s, and uses the Type-C USB3.1 Gen1 interface (theoretical up to 640MB/s) for transmission.
The next is some actual test data of USB drives.
The first is the Crystal Disk Mark test. In the 1G file test, the writing speed of this memory card is 421.62MB/s and the reading speed is 116.42MB/s, which is similar to the official promotion, and even higher.
In the ATTO Disk Benchmark test, the read and write performance of the storage device under different file sizes can be checked according to data packets of different sizes. The actual maximum reading speed of the USB drive can reach 404.51MB/s, and the maximum writing speed can reach 112.04MB/s, and it can achieve the maximum speed when 1-2MB files. When it exceeds 32KB, the USB drive can achieve a write speed of 102.4MB/s, but it is still very excellent. It can still maintain high speed when copying and transmitting some fine files to avoid serious speed drops.
The results obtained by the TxBENCH benchmark test are not much different from those of other tests, with read and write speeds of 410.248MB/s and 114.992MB/s respectively.
In the AS SSD benchmark performance test, the continuous sequential read and write speeds of 1GB data level are 398.87MB/s and 109.14MB/s, which reflect very efficient read and write performance and the high performance performance of Samsung's original NAND chips.
Next, we connect to Macbook Pro to see its speed performance under the Mac OS system. From the actual measured data, it can be seen that the USB flash drive can achieve a continuous write capacity of 101.4MB/s and a 318.8MB/s reading capacity.
Then, we conducted a copying and testing of the video file. We used the 4K high-definition film source for the opening ceremony of the Beijing Winter Olympics . The total size is 21.8G. It can reach a speed of 110MB/s when writing to the USB flash drive, and can achieve a speed of 390MB/s when copying from the USB flash drive. From the running speed details diagram, it can be seen that the speed has not been greatly reduced in reading and writing, which can be said to be very stable.
Not only that, thanks to the versatility of port C, it can also easily connect to various C-port devices, such as mobile phones, tablets, etc. Under the general trend of using multiple devices in the future, C-port USB flash drives will definitely gradually become mainstream products.
Summary: Type-C USB3.1 USB drive MUF-256DA/APC is a very ideal portable USB drive with a stylish and exquisite appearance and solid service guarantee with Samsung, so that users can use it comfortably and reassurely. The powerful original NAND memory chip and stable high-speed transmission also ensure its most basic functional attributes as a USB flash drive. At the same time, its entire series uses C port for transmission, which can be easily competent for use in the future years, allowing it to be transformed from a computer USB drive to an expanded hard drive for mobile phones and tablets, which is very cost-effective. Its price is also very "people-friendly". The size of 1GB is about 1 yuan, and there are 64/128/256 options in total.
