Nowadays, large-capacity storage devices and cloud disks are very common, so few people have mentioned USB disk products at the beginning, but they are used for system installation or mobile office. USB disks are indispensable products, especially for Vlog video creation process. With a USB disk with larger capacity and faster reading and writing, they can better alleviate the lack of memory in mobile phones. If you want to choose, you might as well refer to the Aurico Speed USB disk I bought recently. I personally feel that it is still worth using.
This time I bought the Aurico UFSD-J series USB disk, with a total capacity of 128GB. The outer packaging can clearly see the actual appearance and style of the product. There is a detailed introduction to the physical performance parameters of the product on the back, and a solid hook structure at the top.
There is a thick sponge wrap around the internal USB disk, which can provide relatively strong protection for the USB disk.
whole box products mainly include 128GB Aurico UFSD-J USB flash drive, manual and lanyard.
From the appearance, this USB flash drive has a full metal texture and a very good feel. The shell is made of all-aluminum alloy profiles. The seamless structural design is not only sturdy and durable, but also gives the product excellent dust and waterproof performance and good heat dissipation.
The outer edges with chamfers also increase the specific surface area of the product to a certain extent, increasing the effective heat dissipation performance of the product by about 40%. Even in the hot summer, it can ensure the product's long-term low temperature and stable operation.
Compared with ordinary 16GB USB disk, it has a slightly larger size, with a size of about 70.2mm*21mm*10mm. It supports USB-A port or Type-C port, and has 64G/128G/256G/512G in terms of capacity.
All the edges and corners around it are rounded, and a lanyard hole design is also provided on the edges and corners on the tail end side, which is convenient for U disk to carry when traveling. In terms of performance,
has relatively wide compatibility, can seamlessly connect to major common platforms, and supports USB3.2 Gen1 high-speed transmission protocol, that is, the USB3.0 standard in the old protocol, the theoretical maximum transmission bandwidth can reach 5Gbps, and the theoretical reading and writing performance is slightly inferior to ordinary TLC-type SSD hard disks, but higher than ordinary USB disks. This is a relatively compromise choice in performance selection.
. From the official announcement details page, we can see that the actual reading speed of this USB drive is around 411MB/s and the writing speed is 353MB/s. Even when writing 60GB files, it can be stable and not lose speed, and its performance is relatively strong.
So what is the actual read and write performance of the product? In the Asus Lingyao 14s computer, the USB drive was tested through the common CrystalDiskMark software. The results are shown in the figure below. The actual measurement result was that the product's reading speed was 313MB/s and the writing speed was 278MB/s. The difference from the official reading and writing speed was not large and it is completely acceptable.
full disk write test can basically maintain at 140MB/s without dropping speed. Although the performance is not as good as that of SSD solid-state drives, its performance exceeds that of ordinary USB drives with only 25MB/s of read and write performance, and it is reasonable to have performance compromises. After using
for 30 minutes, the USB flash drive was run again for 30 minutes, and the temperature change was tested at 0min, 10min, 20min and 30min respectively. The results are as follows. At 22 degrees room temperature, the USB flash drive temperature was basically maintained at around 37.5 degrees, and its maximum temperature appeared on the interface, and finally it was basically maintained at 39.5 degrees, with relatively good heat dissipation performance.
When writing to the USB flash drive from the computer using a 64GB file, the USB flash drive's writing speed will basically remain at around 140MB/s even at the last moment.
Copy the 64GB file from the USB flash drive to the computer, and the USB flash drive reading speed is basically maintained at 325MB/s, basically in line with the speed of the previous test.
Summary:
Advantages:
. The product appearance design is simple and beautiful. With the blessing of the integrated seamless aluminum alloy shell and outer edges, it has excellent dustproof and waterproof and heat dissipation performance.
. The product reads and writes faster, close to the speed of ordinary SSD solid-state drives.
. Good compatibility and can be used seamlessly across platforms.
Disadvantages:
. Long-term use of high temperatures, or occasionally stalling.
