Data Storage conversion — common questions
Why does my hard drive show less space than advertised?
Drive manufacturers use decimal units (1 TB = 1,000 GB = 10¹² bytes), but operating systems often display binary units (1 TiB = 1,024 GiB ≈ 1.0995 TB). A '1 TB' drive shows as ~931 GiB in Windows.
What's the difference between Mb and MB?
Mb is megabits (lowercase b = bit), MB is megabytes (uppercase B = byte). 1 MB = 8 Mb. Network speeds are typically in Mbps (megabits/s), file sizes in MB.
Are KB and KiB the same?
No. KB = 1,000 bytes (decimal). KiB = 1,024 bytes (binary). The 'i' is the IEC prefix for binary.
