1.1 Drive capacity and transfer rate measurement
conventions
The computer industry generally adheres to two different conventions for
definitions of the terms megabyte (MB) and gigabyte (GB). For computer RAM, 1
MB is defined as 2
20
= 1,048,576 bytes and 1 GB is defined as 2
30
= 1,073,741,824
bytes. For drive storage, 1 MB is defined as 10
6
= 1,000,000 bytes and 1 GB is defined
as 10
9
= 1,000,000,000 bytes. These two conventions are known as powers of two and
powers of ten respectively. Microsoft deviates from the hard drive capacity
measurement convention and uses the powers of two convention for its operating
systems.
Tableau products report drive capacities and transfer rates according to the industry
standard powers of ten convention. In TX1 screens, reports, and documentation, a 4
GB hard drive stores up to 4,000,000,000 bytes; a hard drive with a 150 MB/sec
transfer rate transfers 150,000,000 bytes per second.
