I'm trying to copy a 40Gb 7zip archive within my network.

The computer sending has an Intel Centrino 130, that's supposed to be 802.11 b/g/n compatible. The router is a Pace 4111n which is also supposed to be wireless n; lastly, the receiving computer uses a usb wireless adapter, TP-LINK WN722N, also wireless n.

With all of the devices wireless n capable, why is the file only copying at 2.7Mb / s? Since there's 8 bits to a byte, shouldn't it be copying the file around 18Mb/s? Is my math wrong?

150Mbps would translate to 8.9MB/s. Remember, all the data has to be sent twice, once to the access point and once from the access point. But that would include no address and control overhead, a perfect 150Mbps on both devices, and no packet loss or retransmission. Actual WiFi throughput being around 1/3 of the maximum is typical given interference and range issues.
