Frequently asked questions
Why does my 500 GB drive show 465 GB?
Drive makers use 1 GB = 1 billion bytes; Windows counts in 1024³ bytes but still says GB. 500 GB is about 465.66 GiB, so nothing is missing.
How fast is a 100 Mbps connection in MB/s?
100 Mbit/s ÷ 8 = 12.5 MB/s; real downloads usually reach 11–12 MB/s.
How many GB are in a TB?
1,000 GB in decimal units, or about 931.32 GiB in binary units.
