Transferring 200 GB over WiFi 7 takes 5m 20s

A 200 GB transfer over WiFi 7 works out to 5 minutes 20 seconds at a realistic 5 Gbps sustained rate. 802.11be's advertised peak is 46 Gbps across the combined 2.4 / 5 / 6 GHz bands — achievable only in lab conditions; real devices deliver 3–6 Gbps on a single high-bandwidth client.

How this is calculated

WiFi 7's big practical win is Multi-Link Operation (MLO), which lets a client use two bands simultaneously, sustaining throughput even if one channel degrades. In a busy apartment building with dozens of overlapping 5 GHz networks, WiFi 7 feels noticeably steadier than WiFi 6 — the peaks are similar but the floor is much higher. Wired 10 GbE still wins for raw speed, but WiFi 7 is finally approaching wired Gigabit as a usable network fabric for bulk transfers.

Verdict

5m 20s for 200 GB over WiFi 7 is genuinely close to a 10 GbE wired run. For the first time, wireless is fast enough that "just transfer it wirelessly" is a reasonable answer for large files.

Frequently asked questions

How long does it take to transfer 1 TB over Gigabit Ethernet?
At a theoretical 1000 Mbps (125 MB/s), 1 TB takes about 2 hours and 13 minutes in ideal conditions. Real-world speeds over Gigabit Ethernet typically top out around 110-115 MB/s due to TCP overhead, so budget closer to 2.5 hours for a full 1 TB copy.
Why is my real transfer speed slower than the cable's rated speed?
Rated speeds are raw signalling rates in bits per second. Protocol overhead (TCP/IP, USB framing, filesystem operations), encryption, small-file latency, and the slowest device in the chain (often the disk, not the cable) all reduce usable throughput. A USB 3.0 port rated 5 Gbps usually delivers around 400 MB/s in practice, not the theoretical 625 MB/s.
What's the difference between megabits (Mbps) and megabytes (MB/s)?
There are 8 bits in a byte, so 1000 Mbps equals 125 MB/s. Network speeds and ISP plans are advertised in megabits per second, while file sizes and storage speeds are measured in megabytes per second. Dividing Mbps by 8 gives you the MB/s figure you actually see when copying files.
How fast is WiFi 6 compared to Gigabit Ethernet for file transfers?
WiFi 6 can exceed Gigabit Ethernet on paper (up to ~9.6 Gbps theoretical) but real-world throughput usually lands between 500 Mbps and 1.5 Gbps depending on distance, interference, and client hardware. For a single large file transfer, wired Gigabit is still more consistent; WiFi 6E or WiFi 7 can edge ahead in ideal conditions.
Is USB 4 or Thunderbolt 4 faster for copying files?
Both use the same 40 Gbps underlying spec and deliver comparable real-world speeds of around 2800-3200 MB/s for sustained transfers. Thunderbolt 4 guarantees the full 40 Gbps and PCIe 32 Gbps tunnel; USB 4 allows 20 Gbps implementations, so check the port's actual spec rather than assuming parity.
Does file size affect transfer speed?
Yes — significantly. Transferring one 50 GB file hits near-maximum throughput, but copying 50 GB of small files (thousands of photos, say) can be 5-10x slower because every file has filesystem and metadata overhead. For large migrations, compressing into an archive first is often faster end to end.
