Computer storage units: Byte, KB, MB, GB, TB, PB, EB, ZB, YB, DB, and NB

In the computer paper, we can see that the 20 data centers of the Dutch bank have around 7 Pb disks and more than 20 Pb of tape storage, and each year 50% ~ 70% increase in storage capacity,

So I want to see how big the pb is, and calculate the size of the 27pb disk is about 0.4 million and 80.

1 Byte = 8 Bit

1 KB = 1,024 Bytes

1 MB = 1,024 KB = 1,048,576 Bytes

1 GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 Bytes

1 TB = 1,024 GB = 1,048,576 MB = 1,073,741,824 KB = 1,099,511,627,776 Bytes

1 PB = 1,024 TB = 1,048,576 GB = 1,125,899,906,842,624 Bytes (13107.2 80 GB

1 EB = 1,024 PB = 1,048,576 TB = 1,152,921,504,606,846,976 Bytes

1 ZB = 1,024 EB = 1,180,591,620,717,411,303,424 Bytes

1 YB = 1,024 ZB = 1,208,925,819,614,629,174,706,176 Bytes

Bytes, KB, MB, GB, TB, PB, EB, ZB, YB, DB, and NB

The smallest basic unit is that Byte should not be known to many people. Next we will show all units in order.

Byte, KB, MB, GB, TB, PB, EB, ZB, YB, DB, NB

I only know the first five. Most people know it. It is calculated based on the rate of 1024.

1 TB = 2 to the power of 40 bytes = 1099511627776 bytes

1 Pb = 2 to the power of 50 bytes = 1125899906842624 bytes

1EB = 60 to the power of 2 bytes = 1152921504606846976 bytes

1ZB = 70 to the power of 2 bytes = 1180591620717411303424 bytes

1YB = 80 to the power of 2 bytes = 1208925819614629174706176 bytes

1DB = 90 to the power of 2 bytes = 1237940039285380274899124224 bytes

1NB = 100 to the power of 2 bytes = 1267650600228229401496703205376 bytes

During the calculation, I found that the calculator that comes with XP could not be computed at all, and I had to re-enter a calculator that could be computed.

Looking at these numbers, you don't feel anything. Now let's just look at it. Let's take NB as an example. (Why is NB? Is it very NB where it can be used ?)

We are about to step into the TB era. Now the standard weight of 1 TB hard drive is 670 GB (almost)

1NB = 2 to the power of 60 TB = 1152921504606846976 TB = 1152921504606846976 1 TB hard drives

The total weight is about 7.72457e+08 million tons. Currently, the largest ship, nock Nevis, carries 0.56 million tons.

That is to say, the hard disk that stores 1NB data needs to be pulled back and forth at least 1 379 388 229 1.4 billion times to about times before the data can be shipped to the location, it is estimated that reimbursement will be required for all 1000 nononoisy noisy accounts.

Now, I understand the concept of 1NB. Is it a well-deserved NB? We have been developing in the TB storage era for so many years. I don't know if we can develop into the NB era before the destruction of the world... Byte, KB, MB, GB, TB, PB, EB, ZB, YB, DB, NB
