About Megabyte per second (MBps)
A megabyte per second (MB/s or MBps) equals 8,000,000 bits per second and is the practical unit that most users encounter when watching a download progress bar. A 100 Mbps broadband connection downloads at up to 12.5 MB/s; a USB 3.0 drive transfers at 50–100 MB/s; an NVMe SSD reads at 3,000–7,000 MB/s. Understanding MB/s alongside Mbps resolves the common frustration of seeing a "1 Gbps" plan deliver "only" 125 MB/s — the two figures are consistent, not contradictory.
A 100 Mbps home broadband plan delivers up to 12.5 MB/s in a download manager. A USB 3.2 flash drive typically writes at 50–200 MB/s.
About Mebibit per second (Mibps)
A mebibit per second (Mibps) equals 1,048,576 bits per second — the binary IEC equivalent of megabit per second. It is approximately 4.9% larger than 1 Mbps. Mibps appears in network performance specifications written to IEC standards, and in operating system tools on Linux and some Unix variants that apply binary prefixes strictly. When a Linux system reports "ethtool: speed 100MiB/s", this distinction from 100 MB/s (decimal) matters in precise bandwidth budgeting.
A 100 Mibps figure represents 104.86 Mbps in decimal — about 5% more data. Network engineers use Mibps when exact binary calculations are required for buffer sizing.
Megabyte per second – Frequently Asked Questions
Why does copying files to a USB drive slow down partway through?
Many USB drives use a small SLC cache for initial writes at high MB/s, then slow dramatically once the cache fills and data writes to slower TLC/QLC NAND. A drive that starts at 200 MB/s might drop to 20–30 MB/s after the first few gigabytes. Check sustained write speed reviews, not just peak numbers.
What MB/s do I need for video editing?
Editing 4K ProRes footage requires about 200–400 MB/s of sustained read speed. 8K RAW can demand 1,000+ MB/s. A SATA SSD (550 MB/s) handles 4K fine, but 8K workflows really need NVMe drives at 3,000+ MB/s. The timeline scrubbing experience directly correlates with MB/s.
How do I tell if a speed test result is in MB/s or Mbps?
Look at the capitalisation: lowercase "b" (Mbps) means megabits, uppercase "B" (MB/s) means megabytes. Most speed test websites (Speedtest by Ookla, fast.com) default to Mbps. If your result seems 8× lower than expected, you are probably reading MB/s where you expected Mbps.
What is the fastest consumer storage in MB/s as of 2026?
PCIe 5.0 NVMe SSDs hit 12,000–14,000 MB/s sequential read speeds. That is fast enough to load an entire 50 GB game in about 4 seconds. PCIe 6.0 drives, expected soon, will double this again to roughly 25,000 MB/s.
Why is network file sharing slower than local disk speed?
Network transfers add latency, protocol overhead (SMB, NFS), and are limited by the network link speed. A file on a local NVMe SSD reads at 7,000 MB/s, but sharing it over a 1 Gbps network caps throughput at 125 MB/s. Even 10 GbE only gives 1,250 MB/s — a fraction of modern SSD capability.
Mebibit per second – Frequently Asked Questions
When would I encounter mebibits instead of megabits?
Mainly in Linux system tools, IEC-compliant technical specifications, and some enterprise storage documentation. The iperf3 network testing tool can report in Mibps if configured to use binary units. Most consumer-facing software and ISPs use megabits exclusively.
How do I convert Mibps to Mbps?
Multiply by 1.048576. So 100 Mibps = 104.86 Mbps. To go from Mbps to Mibps, divide by 1.048576. At small values the difference is negligible, but at gigabit scales it can mean a meaningful amount of data.
Why does Linux sometimes use binary units for networking?
Linux kernel developers historically followed IEC recommendations to use binary prefixes where applicable. Some tools like dd and rsync default to binary (MiB/s) for disk operations. However, network-facing tools like ethtool and ip still use decimal Mbps because that is what the hardware reports.
Does the 5% difference between Mibps and Mbps matter in practice?
For casual use, no. For capacity planning and SLA compliance, yes. If a contract guarantees 100 Mibps and the provider measures in Mbps, the customer might get 100 Mbps (only 95.4 Mibps) and technically be short-changed. Data center SLAs should specify which unit system applies.
Is my ISP cheating me by using megabits instead of mebibits?
No — ISPs legitimately use decimal megabits because Ethernet and fiber standards are decimal. A "100 Mbps" plan genuinely delivers 100,000,000 bits per second. The confusion arises only when comparing with binary-unit tools. ISPs are not hiding anything; the two systems just coexist awkwardly.
