based on the following values:
1 KB = 1,000 bytes
1 MB = 1,0002 bytes
1 GB = 1,0003 bytes
1 TB = 1,0004 bytes
1 PB = 1,0005 bytes
Logical storage capacity values (e.g., logical device capacity) are calculated
based on the following values:
1 KB = 1,024 bytes
1 MB = 1,0242 bytes
1 GB = 1,0243 bytes
1 TB = 1,0244 bytes
1 PB = 1,0245 bytes
1 block = 512 bytes
