The biggest difference between the solid-state flash drive and the ordinary USB flash drive is that the size is about the same, but the read and write speed is much faster, for example, the two Kingston and ADATA ordinary USB flash drives in my hand have a read and write speed of only tens of megabits per second, while the US2 solid-state flash disk of Lanco can pass hundreds of megabits per second, and the storage efficiency is about 10 times different.
Langke US2 provides a five-year warranty, non-human quality problems during the warranty period to support replacement repair, the capacity is 128GB/256GB/512GB/1TB four versions, the price is 159 yuan / 199 yuan / 339 yuan / 499 yuan, the most cost-effective must be 1TB capacity, but I will use a mobile hard disk to store large-capacity data, this is just used to access some temporary files at work, so 128GB is enough.
The size is 165.4*20.2*9.6mm, the weight is about 24g, the shell is made of silver zinc alloy, vacuum plating process, the texture is very good, the head hat and fuselage are designed 1:1, which meets the symmetrical aesthetic requirements of obsessive-compulsive disorder.
Type-A interface, USB 3.2 logo printed on the inside of the fuselage, in fact, the US2 supports the USB 3.2 Gen 2 transmission standard, with a read speed of 530MB/s and a write speed of 450MB/s.
Brief evaluation and quick test are not nonsense, directly on the machine measurement, CrystalDiskMark speed measurement, sequential read 526MB/s, sequential write 447MB/s, and the official parameters are basically the same.
TxBENCH's algorithm is different, and the results fluctuate a bit, with a read speed of 497MB/s and a write speed of 358MB/s, which is still within the normal range overall.
30GB large file write, the whole process is stable at about 335MB/s, no speed drop, a total of 3 tests, the results are basically the same, no fluctuations.
The default file format is exFAT, which can be read and written normally for Windows and Mac, and can be recognized normally when plugged into my MacBook Pro.
If you add an A2C adapter and plug it into your phone, it will work normally, I tried it, and Android and my iPhone 15 Pro Max are fine.
Finally, make a summary:Langke US2The speed、Stability and compatibility are no problem,PC、Notebook、Mobile phone can be used,U disk size,The speed of the solid state drive,Take into account portability and efficiency,128GBThe price is159element,Compared with similar products,It's decent,There are more expensive than it,There are cheaper than it,But I probably compared,The speed standard is the highest among the competing products,For example, SanDisk's CZ880 128GB,Read420MB/s,Write380MB/ S, the price is 229 yuan, so look at it, it is still a little advantage.
