Megabyte per Second (MB/s)
A megabyte per second is one million bytes each second, equal to 8 Mbit/s. Download managers, Steam and drive benchmarks report MB/s.
Symbol: MB/s
Quantity: data transfer rate (bandwidth)
SI relation: 1 MB/s = 8000000 bps (exact)
Derivation: 1 MB/s = 10⁶ B/s = 8 Mbit/s.
Exact: yes, by definition
Typical uses
- Download and copy speeds
- SSD and hard-drive benchmarks
- USB transfer rates
