One gigabyte (GB) is equal to one billion bytes, one terabyte (TB) is equal to 1,000GB (one trillion bytes), and

one petabyte (PB) is equal to 1,000TB (one quadrillion bytes) when referring to solid-state drive or hard drive

capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the drive,

the computer’s operating system, and other factors.
