Comparing storage capacities requires understanding the magnitude of each unit. The hierarchy from smallest to largest is megabytes (MB), gigabytes (GB), terabytes (TB), and then petabytes (PB).1 PB (petabyte) =
1,000 TB (terabytes)100 TB = 100 terabytes9,000 GB = 9 terabytes9,900 MB = 0.0099 terabytesTherefore, 1 petabyte (PB) is significantly larger than the other options listed.References: Storage capacity units and conversions are covered in IT fundamental courses and materials, including those by CompTIA.
