Calculation force of 1TB
Under the current difficulty, 1t mining machine can dig about 0.0268 BTC per day, which is about 1 bitcoin in 50. It is about 100 yuan in RMB. How much bitcoin you can dig in a day depends on how many shares you hold, that is, computing power. However, the computing power is floating. When the overall computing power is low, it's more. Otherwise, it's less. You can go to Babbitt's website to check the specific content when you have time< br />
The actual capacity of 1t hard disk is about 931g< br />
1TB of mobile hard disk is equal to 1000g
The conversion ofTB (T) to G (GB) should adopt the international system of units (SI) decimal conversion
in Si decimal system:
1TB = 10 ^ 3 GB = 10 ^ 6 MB = 10 ^ 9 KB = 10 ^ 12 byte
therefore, 1TB = 1000gb
extended data:
when viewing a mobile hard disk with a nominal capacity of 1TB in the computer operating system, the theoretical capacity is about 931gb, but the actual capacity is slightly less than this value. This seemingly shrinking capacity is e to the difference between the "nominal capacity" of the hard disk and the calculation method of the computer system
for storage procts including hard disk, the manufacturer calculates the nominal capacity in decimal system: 1KB = 1000bytes, 1MB = 1000KB, 1GB = 1000mb, 1TB = 1000gb
The capacity statistics of storage devices by computer operating system are calculated in binary mode: 1KB = 1024bytes, 1MB = 1024KB, 1GB = 1024MB, 1TB = 1024gbtake a hard disk with a nominal capacity of 1TB as an example: in decimal calculation: 1TB = 1000gb; When the computer operating system is converted to binary, the actual capacity should be 1000gb * 1000 * 1000 / 1024 * 1024 * 1024 ≈ 931.32gb
= 1024
GB
the largest
value is
1GB = 1024MB
1MB = 1024KB
in Si prefix list, t is Tera, translated as Tai, AI is e (exa), so it is called Taizhao
above.
The capacity of 1t = 1024g hard disk is based on 1000
1t = 1000g, including the space occupied by the system, the actual available capacity is only about 950g
1TB is 1024gb in theory, but manufacturers generally sell 1000gb hard disk. Because hard disk manufacturers do not use the theoretical standard value for better calculation, but take 1000 as the conversion unit to facilitate calculation
even according to the manufacturer's standard, 1TB hard disk is equal to 1000g, but when we actually partition the hard disk or calculate the capacity of 1TB hard disk in the system, we will find that 1TB hard disk does not have 1000g, but only about 930g. The main reason is that there are firmware programs inside the hard disk, which are written by the manufacturer and we can't see, But actually this part of capacity still exists
extended materials:
the world's first 1TB hard disk was launched by Hitachi global storage in Jingdong Mall on May 16, 2007, and named as deskstar 7k1000
The Hitachi deskstar 3.5-inch 7k1000 hard disk is a 1TB proct, with sataii interface, 7200 rpm, delay of 4.17ms, seek time of 8.5ms, 32m cache, 5-disk and 10 head designthe price of Hitachi 1TB hard disk launched by jd.com is 3199 yuan. On January 24, 2011, Jinshan network announced the launch of 1TB (about 1024gb) network hard disk "t disk"
