How many grams is a t of a mobile hard disk?
1TB of mobile hard disk is equal to 1000G, which is displayed as about 932GB in Windows operating system.
To convert TB (T) to G (GB), the International System of Units (SI) decimal conversion should be used.
In International Units (SI) decimal:
1TB = 10^3 GB= 10^6 MB = 10^9 KB =10^12 Byte
So, 1TB=1000GB.
However, in the Windows operating system, Windows Explorer uses the IEC standard (binary) for calculation, 1TB=(1000^12)/(1024^3)≈931.32GB.
So, the capacity of a 1TB hard drive in the Windows operating system will be about 932GB.
Extended information
1TB is the manufacturer's nominal capacity, 1000GB is the actual capacity of the hard drive, and 932GB is the displayed capacity in the Windows operating system.
The reason why the actual capacity converted from the nominal capacity is different from the capacity displayed in the Windows operating system:
(1) Because the nominal capacity of the hard disk is calculated differently from the Windows computer system.
(2) When the hard disk leaves the factory, the written manufacturer information, hard disk information, firmware and other files, as well as the boot partition, NTFS formatting and some bad blocks will occupy some space.
The world's first 1TB hard drive was launched on May 16, 2007 by Hitachi Global Storage Company, named Deskstar 7K1000.
Hitachi Deskstar 3.5-inch 7K1000 hard drive is a 1TB product, using SATAII interface, 7200 rpm, delay 4.17ms, seek time 8.5ms, 32M cache, 5-disc 10-head design, listing price is 3199 yuan
