A terabyte comprises an ext than 1 trillion bytes. Discover how the storage measurement range was created and where a terabyte stands among other devices of measure up today.

As the quantity of data we generate continues to grow, so does the perform of units to measure it. The humble byte is currently attached come a slew of prefixes denoting vast amounts of data.


A terabyte (TB), for example, is equal to 1012 bytes. Hitachi exit the first terabyte-level tough drive in 2007, and also today, HDDs have the right to hold as much as 18 TB that data. The largest SSDs can hold as much as 100 TB. An LTO-9 ice cartridge attributes compressed capacity as much as 45 TB.

On their own, these massive storage capacities are nearly incomprehensible. By to compare these devices of measurement, however, it"s easier to get a clean picture. To recognize what a terabyte is, it help to recognize what is bigger and smaller than one.

Is a TB bigger than a GB?

A terabyte is bigger than a gigabyte.

A terabyte is same to 1,024 gigabytes (GB), which itself is equal to 1,024 megabytes (MB), if a megabyte is tantamount to 1,024 kilobytes. Every storage measuring units -- kilobyte, megabyte, terabyte, gigabyte, petabyte, exabyte and so ~ above -- space multiples of a byte.

How the size range was created

Bytes organize a wire of bits, frequently eight because that most computer system systems. A bit, brief for binary digit, has actually a solitary binary worth of either 0 or 1 and is the smallest unit the data in a computer system system. Memory or warehouse devices commonly store the worth of a bit over or below a designated level of electric charge in a solitary capacitor. A byte stop its cable of bits for this reason they have the right to be used in a larger unit for applications or OS purposes.

Werner Buchholz is attributed by Fred Brooks -- author of the classic software engineering tome The Mythical Man-Month: Essays on Software Engineering and very early IBM hardware architect and IBM System/360 OS job manager -- together the originator that the ax byte. Follow to Brooks, Buchholz come up with byte while helping to style IBM"s an initial transistorized supercomputer, the 7030 STRETCH, in 1956.

Terabyte vs. Various other byte measures

Measurements the are smaller sized than a terabyte include a kilobyte, megabyte and also gigabyte.

A terabyte is one of the biggest units of warehouse media that commodities on the industry use today, yet it is not the greatest unit of measure up in data storage. Units larger than a terabyte include a petabyte, exabyte, zettabyte, yottabyte and also brontobyte. A geopbyte is also larger 보다 a terabyte and also refers to 1030 bytes, or 1,000 brontobytes.

Additional units of measurement come to be necessary as the lot of data in the human being increases. And also it"s not going to slow-moving down any type of time soon. Actual journey capacity may not right now go beyond the terabyte scale, but this will certainly undoubtedly readjust as warehouse media technology evolves.

How lot data is in a terabyte?

A terabyte has actually a storage drive capacity of around 1 sunshine bytes or, an ext specifically, 1,099,511,627,776 bytes; 1,073,741,824 kilobytes; or 1,048,576 megabytes.

In valuable terms, a terabyte that data is equivalent to the following:

728,177 floppy disks 1,498 CD-ROM discs 212 DVD discs 40 single-layer Blu-ray discs 85,899,345 pages that Word documents 132,150 650-page books 500 hrs of movie 1,000 hrs of video clip 310,000 picture 17,000 hrs of music
