With the popularization of the USB-Type C data interface, more and more mobile phones, laptops, and desktops have begun to lay out the C-port matrix in large quantities.
However, the personal storage devices (U disk, mobile hard disk, etc.) that are relatively slow to update are still mainly based on the A port, which is easy to cause many unnecessary troubles. In the disk, but the computer can only use the C port, which will cause a very embarrassing situation.
Therefore, in 2022, your U disk and other devices should be updated to the form of the C port, which is not only more convenient in connection, but also has a considerable increase in speed.
A Samsung Type-C USB3.1 U disk MUF-256DA/APC that I am evaluating today is a good choice.
This USB flash drive is Samsung’s latest USB3.1 Gen1 C port device. It adopts Samsung’s international packaging style on the packaging, with striking “Type-C” and “256GB” logos.
The product information of the USB flash drive is printed on the back of the package, including some product safe use ranges, including:
It can still be used after 72 hours of immersion in 3% sodium chloride salt water at a depth of 1 meter
The operating temperature range is 0°C to 60°C, and the non-operating temperature range is -10°C to 70°C.
X-ray protection against 100mGy
Antimagnetic 15000G (Gauss)
shockproof
When I opened the package, my first impression of this USB flash drive was that it was very light. It is based on sturdy synthetic materials and weighs only 3.4g, making it as light as nothing in my hand.
The surface of the U disk adopts a dark blue design, and is given a special aurora blue coating, so that the U disk will have a “bright” effect under the refraction of light, and there is a hint of metal texture.
At the same time, the surface of the U disk has a multi-faceted curved design, and it also has a streamlined body, which makes it very delicate. Whether it is for personal use or lending to others, it can highlight the user’s taste.
There are lanyard holes on the USB cover and the fuselage, which are convenient for users to tie with a string to avoid the loss of the USB cover.
In the storage performance part of the U disk itself, it uses Samsung’s original NAND flash memory. up to 640MB/s) for transfer.
Next is the actual test data of some U disks.
The first is the Crystal Disk Mark test. In the test of 1G file, the write speed of this memory card is 421.62MB/s and the read speed is 116.42MB/s, which is similar to the official promotion, or 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 U disk can reach 404.51MB/s, the maximum writing speed can reach 112.04MB/s, and the maximum speed can be achieved when the file is 1-2MB.
When the size exceeds 32KB, the U disk can display a writing speed of 102.4MB/s, which is still very good. It can still maintain high speed when copying and transferring some small files, avoiding serious speed drop.
The results obtained by the TxBENCH benchmark test are also similar to other similar test results, with read and write speeds of 410.248MB/s and 114.992MB/s, respectively.
In the AS SSD benchmark performance test, the sequential read and write speeds of 1GB data level are 398.87MB/s and 109.14MB/s, showing quite efficient read and write performance and the high performance of Samsung’s original NAND chips.
Next, we connected the Macbook Pro to see its speed performance under the Mac OS system. It can be seen from the measured data that the USB flash drive can achieve a continuous write capability of 101.4MB/s and a read of 318.8MB/s. ability.
Then, we conducted a copy test of a video file. We used the 4K high-definition film source of the opening ceremony of the Beijing Winter Olympics, with a total size of 21.8G.
It can achieve a speed of 110MB/s when writing to the U disk, and 390MB/s when copying from the U disk. From the detailed diagram of the running speed, it can be seen that the speed of reading and writing is not large. The rate of decrease can be said to be very stable.
Not only that, thanks to the versatility of the C port, it can also easily connect to various C port devices, such as mobile phones, tablets, etc. Under the general trend of multi-device use in the future, the C-port U disk will definitely gradually become a mainstream product.
Summarize:
Type-C USB3.1 USB flash drive MUF-256DA/APC is an ideal portable USB flash drive, with a stylish and refined appearance, solid performance and Samsung’s service guarantee, allowing users to use it comfortably and with confidence.
The powerful original NAND memory chip and stable high-speed transmission also ensure its most basic functional attributes as a U disk.
At the same time, its entire series uses the C port for transmission, which can easily be used for many years in the future, making it from a computer U disk to an expansion hard disk for mobile phones and tablets, which is very cost-effective.
Its price is also very “close to the people”, the size of 1GB is about 1 yuan, and there are 64/128/256 options.
