<Note for storage capacity calculations>
 Memory capacities and requirements, file sizes and storage requirements, etc. must be
calculated according to the formula 2
calculations by 2
1 KB (kilobyte) = 1,024 bytes
1 MB (megabyte) = 1,048,576 bytes
1 GB (gigabyte) = 1,073,741,824 bytes
1 TB (terabyte) = 1,099,511,627,776 bytes
 As for disk capacities, they must be calculated using the formula 10
results of calculating the above example capacities using 10
1 KB (kilobyte) = 1,000 bytes
1 MB (megabyte) = 1,000
1 GB (gigabyte) = 1,000
1 TB (terabyte) = 1,000
