How to distinguish the quality of a USB flash drive

You have too many questions, let me talk about them one by one.

There seem to be a lot of affordable brands of U disk, and the U disk I have used is very easy to use, and the U disk is generally not broken.

The warranty period of the portable hard drive is useless, and you will not repair it at all.

My classmate has a hard disk in Shenzhou, and I have used it for a long time, and I haven't heard of any problems.

It's better to buy a new one for a portable hard drive and a USB flash drive to repair, and it's not much expensive anyway, unless you have important files in the disk.

In general,Mobile hard disk and U disk are not bad.,You can buy it with confidence.,I came to freshman U disk is128M,Because it's too small enough to buy this2G,It's all Taidian,It's never broken。

The Sony mobile hard drive I bought 80g is only more than 500 oceans, and the quality is very good. And IBM's is also very good, if you want to ***, then don't try to buy domestic drops cheaply!

It's still a little better for the brand, the Jinshidun and Patriot I use are good, and Shenzhou's dare not compliment.

I haven't broken the hard disk of Shenzhou for three years, and don't buy Tsinghua Unisplendour on the USB flash drive.

It's cheap to buy a USB flash drive now, and the Patriot is at the forefront of technology. I'm mainly afraid that I won't be able to get out the information if it is broken, so it's better to buy a good brand.

Don't think about repairing the USB flash drive. Throw it away and buy a new one, because the bad one is basically the chip itself, and it is not as cost-effective as buying one to repair one.

Shenzhou's hard disk price is okay, but the quality is not good, including the computer is not very good

1. Look at the reading and writing speed: the reading and writing speed of the U disk is not slow, the general U disk writing speed can reach 8-10MB s, and the read speed can reach 15-20MB s.

2. Look at the material: When buying a USB flash drive, you should also look at the shell material of the USB flash drive, whether it is dust-proof, drop-proof, anti-static, etc. Generally speaking, the shell made of metal is wear-resistant, but the seismic performance is reduced, and the shell made of engineering plastic or rubber trembling material has good shock and drop resistance, but is not wear-resistant.

3. Look at the brand service: the product quality of big brands is often guaranteed, the after-sales service is better, and the powerful mobile storage manufacturers have achieved better service standards, which can directly meet the needs of users in various regions in the pre-sale, in-sale and after-sale consultation, experience and repair, greatly shorten the service cycle and ensure the quality of service.
