Mebibyte per Second (MiB/s)
A mebibyte per second is 1,048,576 bytes each second, about 8.39 Mbit/s. Many operating systems and tools show copy speeds in MiB/s labelled “MB/s”.
Symbol: MiB/s
Quantity: data transfer rate (bandwidth)
SI relation: 1 MiB/s = 8388608 bps (exact)
Derivation: 1 MiB/s = 1,048,576 B/s.
Exact: yes, by definition
Typical uses
- File copy dialogs
- Linux and storage benchmarks
