Gigabytes per second to megabytes per second converter
Convertersconversion pair
Convert GB/s to MB/s instantly: 1 GB/s is 1,000 MB/s. Useful when a spec sheet and a benchmark insist on different units.
the spec says gigabytes, the benchmark says megabytes, and both are right.

pro tips
Multiply by 1,000, not 1,024. GB/s and MB/s are decimal; GiB/s and MiB/s are the binary cousins.
A 10 GB/s drive is 10,000 MB/s, which is why the benchmark and the box rarely print the same number.
Sustained writes are usually lower than the peak read figure on the box. Check both before buying.
what it does
One gigabyte per second is 1,000 megabytes per second. Multiply by a thousand and the headline storage figure becomes the one a benchmark tool is likely to print.
This is the conversion for comparing a drive's marketing number with a real copy test. A drive sold as 7 GB/s is 7,000 MB/s, and a benchmark that reports 6,800 MB/s is describing the same class of hardware with a little real-world loss.
Examples: 0.5 GB/s is 500 MB/s, 2 GB/s is 2,000 MB/s, and 10 GB/s is 10,000 MB/s. At the top end, the PCIe generation and the number of lanes matter more than the label on the box.
Type a gigabytes-per-second value and the widget returns megabytes per second live. Click to copy, or swap to the MB/s-to-GB/s page when the source is the other way round.
quick answers
How many MB/s is 7 GB/s?
7,000 MB/s. The prefix step is 1,000, so the number grows by three zeros.
Why does my drive not reach the advertised GB/s?
Peak figures assume ideal conditions: large sequential transfers, a fast interface and an empty cache. Real workloads are messier.
Is GB/s the same as Gbps?
No. GB/s is gigabytes per second, Gbps is gigabits per second. One byte is eight bits, so 1 GB/s is 8 Gbps.
