Why does my hard drive show less space than advertised?

Drive manufacturers count in decimal, where 1 GB is 1,000,000,000 bytes, while operating systems usually display binary gibibytes of 1,073,741,824 bytes. A 1 TB drive therefore shows as roughly 931 GB even though nothing is missing.

What is the difference between MB and MiB?

MB is the decimal megabyte of 1,000,000 bytes; MiB is the binary mebibyte of 1,048,576 bytes. The distinction matters most for storage marketing and network throughput figures, where decimal units are the norm.

What is the difference between megabytes and megabits?

A byte is eight bits. Internet plans are advertised in megabits per second, so a 100 Mbps connection tops out at about 12.5 megabytes per second of actual download speed.

How much storage does an hour of video use?

Roughly 1 to 2 GB per hour for 1080p streaming, 7 to 10 GB per hour for 4K streaming, and far more for recorded footage. Use the converter to translate a bitrate in Mbps into an hourly size before planning storage.
