A byte refers to a quantity of data. However, the modern USB stick, computer, or other data carrier offers capacities well beyond 1,000 bytes. Therefore, information units that are multiples of a byte are in use. Gigabytes and terabytes are common measures of memory for data storage capacity. In the case of server centers and mainframes, the amount of data well exceeds that of private storage devices which is where petabytes come in. There are 1,024 terabytes in one petabyte.
Given rapid digitalization, the increasing popularity of streaming services and continued technological developments, it’s only a matter of time before petabytes will become more relevant to the average user. There’s already a growing demand for larger storage capacities and data carriers continue to scale their volumes. An SSD in 2.5-inch format now stores up to 15 terabytes. For 1 petabyte of information, around 68 SSDs are required.
