2TB
2TB refers to two terabytes of digital information storage. In decimal notation, a terabyte equals 1,000,000,000,000 bytes, so 2 TB equals 2,000,000,000,000 bytes. In binary terms, data storage is often described as tebibytes (TiB), where 1 TiB equals 1,099,511,627,776 bytes; therefore 2 TB is approximately 1.818 TiB. Because many systems and vendors label capacity using decimal terabytes, the two figures can differ on the same drive depending on how the manufacturer and the operating system report size.
In practice, operating systems may report capacities in TiB or GiB, while drives are marketed as TB.
2 TB is a common size for internal hard drives and solid-state drives, as well as external
There are trade-offs between the media types. Hard disk drives of 2 TB offer large capacity at
