Convention for Storage Capacity Values

Physical storage capacity values (e.g., data drive capacity) are calculated based on the following values:

1 KB = 1,000 bytes 1 MB = 1,000 1 GB = 1,000 1 TB = 1,000 1 PB = 1,000

Logical storage capacity values (e.g., logical device capacity) are calculated based on the following values:

1 KB = 1,024 (2 1 MB = 1,024 KB or 1,024 1 GB = 1,024 MB or 1,024 1 TB = 1,024 GB or 1,024 1 PB = 1,024 TB or 1,024 1 block = 512 bytes
