How to buy a USB flash drive How to choose a good USB flash drive?

At present, the mainstream ones are 1G and 2G, depending on which one needs to be chosen.

If you buy, you must buy a good brand of U disk, the best domestic one is Langke's, but the American brand is more recommended, followed by the Taiwanese brand, the quality of the American brand is generally good.

The boss of the USB flash drive is Sandisk, followed by Kingston, Transcend, PNY and so on.

** Also the most expensive on Sandisk.

A 1G SanDisk costs more than 100 points, and a 2G one costs about 160.

The 1g Kingston is less than 100, and the 2g is about 140.

The read speed of SanDisk is 18M s, the write speed is 4M S, the read speed of Kingston is 10M s, and the write speed is 3M S, which are faster than domestic brands.

If you want to be cheaper, you can try to buy an SD card and add a card reader, so that the camera and mobile phone can be used and used as a USB drive.

The cost performance of 1G and 2G is good.

If you don't need it, just buy 1g. Tsinghua Ziguang seems to be the cheapest, 1g of our 68 yuan. In terms of quality, the purple light is not as good as others, and the people who sell it say so.

But mine is the purple light, I haven't done anything after a year, and most of my classmates have bought purple light, and there has been no problem, it's cheap. There are very few problems with this thing on the USB flash drive.

In addition, the golden blunt is also good, the quality is first-class, and it is slightly more expensive. My classmate has one.

What city are you in? Why is it so much more expensive on our side. The two types you mentioned both sell for more than a hundred in Wuhan.

Some of the relevant characteristics can be seen from the surface workmanship. The U disk with fine workmanship, internal circuits and chips will not be too bad. The inferior USB flash drive shell feels rough and has poor durability.

Aesthetics is secondary, and the key is to protect the chip inside. This depends on the physical protection of the product, for example, some products on the market use metal materials as shells in order to look good, but at the same time, they reduce the seismic performance of the U disk, in contrast, the use of engineering plastics or rubber materials can provide better shock and drop resistance.

Look at the read and write speed of the USB flash drive. This can only be said to be a USB flash drive on the premise that it can be compared and tested, the faster the better. If you buy a USB flash drive online, some USB flash drives will generally explain the "comparative test" and "reading and writing speed" in the description, and the opposite quality is often "how many songs can be saved" "how many movies can be saved" and "xx**" These avoidance of the important and light product descriptions.

Look at the quality of after-sales service. Since the USB flash drive will often be carried and plugged and unplugged on different computers, it is easy to be damaged, so it is necessary to choose a store with after-sales guarantee. Looking at the quality of after-sales service is always an important indicator that needs to be measured when buying goods.

To buy products from regular manufacturers, you can buy them on Jingdong and other **.
