A 20g ordinary mobile hard drive costs 420! It's not cost-effective, it's better to ask for a 40g 550!

Anonymous users2024-02-02The reason why USB flash drive is expensive:
1. The capacity of the U disk is large, such as 32G and 64G, which are more expensive.
2. The speed of the U disk is fast, such as the interface speed is a high-speed U disk, which is more expensive.
3. The manufacturer of the U disk is a big brand, such as Lenovo U disk is more expensive.
4. The workmanship, appearance, and delicacy of the U disk are also a little more expensive.
5. The channels of the U disk are different, and the merchant has to buy it a little more expensive, or it will not be able to make money.
In fact, this conclusion should be incorrect, or depending on the specific problem, let's analyze it for you: Because the U disk manufacturer is calculated according to the conversion unit of 1g=1000m, and the computer is calculated according to 1g=1024m, so the actual capacity of the U disk with a nominal 8G capacity on the market is only 8*1000=8000M, not 8*1024=8192M as we understand it. In this 8000m capacity, divide 8000m by 1024m g (computer) =, and then deduct some system files to occupy the space that may be left, so the 8g**u disk you bought, the capacity displayed on the computer is not 8g, generally floating left and right. >>>More
Hard disk than USB flash drive.
The speed is much faster, so it is very fast for the U disk to copy files to the hard disk, and the U disk only reads; On the other hand, the write speed of the USB flash drive is not as fast as the hard disk, which causes the hard disk to copy files to the USB flash drive much slower, and the speed keeps jumping because the file is slower than a large file if it is fragmented. >>>More
Your computer should be a newly bought Windows 7 system, right? >>>More
Summary. Precautions for the use of U disk: 1. The U disk generally has a write protection switch, but it should be switched before the U disk is inserted into the computer interface, and should not be switched in the working state of the U disk. >>>More
