How much does a 20G portable hard drive cost

It's about 100 yuan, but it also depends on the place!

For example, Zhongguancun: No, Shanghai Qiujiang Road: about 130 yuan Xujiahui's Bainaohui:

No, Shenzhen fills: 80 yuan, Guangzhou Shantou: 75 yuan, Fuzhou Electronic City:

95 yuan, Fuzhou Xindian thrift market: 90 yuan, Zhejiang Xiangshan: 105 yuan.

That's all I know.

The one on the third floor, if you want it, I have it here, and sell it to you!

Is there such a big one?,Why don't I know?,Don't say it's stopped.,I don't see that it's ever been produced.,Two g of it is almost 200 yuan.,20g is at least more than 900.。

Dizzy,20G mobile hard disk is only about 320 yuan,There must be a lot of people who buy it.。。

As far as I know, the cheap ones are more than a thousand, usually about 1400.

There is no 20g for the new one, so it is better to buy a 40g or 60g one directly. Buy your own hard drive, and then buy a box to pack yourself.

Also, how long has it been since you been to the computer city on the 3rd floor?

Laptop hard disk is about 40g500, 60g600, 80g700. There is a slight difference between different speeds.

Box of about 100 is good.

Buy a second-hand 20g hard disk by yourself, and then go with a hard disk case, it should not exceed 150 yuan.

Yes, when is the 3rd floor?

There's that thing there.

1TB of a portable hard disk is equal to 1000G.

The conversion of tb(t) to g(gb) is based on the International System of Units (SI) decimal conversion.

In International Units (SI) Decimal:

1tb = 10^3 gb= 10^6 mb = 10^9 kb =10^12 byte

So, 1TB = 1000GB.

1TB of a portable hard drive is equal to 1024G. TB, also known as terabyte terabyte, is the storage capacity unit of the computer, generally memory will not have TB level, TB level is generally hard disk, the system recognition of memory is in byte bytes, and each byte is composed of 8 bits of binary numbers, that is, 8bit is a bit is also called.

1TB memory definitionAccording to the binary method of the computer, the conversion multiplier is 1024, so 1TB is equal to 1024GB, 1TB is equal to 1000GB is equal to 10000MB Basically, the capacity of most hard disks is equal to the actual nominal capacity, the reason is simple, 1TB is not equal to 1000GB, nor is it 1024GB.

In the computer, binary system is used, and the theoretical value is the value used for learning in the computer or textbook, which is usually converted to 1024 times in the textbook or the internal calculation of the computer.
