Frequently asked questions
- Why doesn't 1000 MB equal 1 GB?
- Operating systems usually use binary units: 1 GB (technically 1 GiB) = 1024 MB. Drive manufacturers often use decimal GB (1000 MB), which is why a '500 GB' drive shows as roughly 465 GB in your OS.
- Does this matter for mobile data plans?
- Carriers typically advertise decimal GB (1000 MB). The values shown here use the binary convention, so they may differ by a few percent from a carrier's metering.
