Comcast revealed last year that it intended to deliver a special high speed option for Internet service at up to 105Mb/s.  An article in USA Today reports:

"Extreme 105, [will be] available to consumers in more than 40 million homes in San Francisco, Seattle, Denver, Chicago, Boston, Philadelphia, Washington, D.C., and Miami, among others.

The service delivers data at 105 megabits per second — more than 60 times faster than a T-1 line, which most businesses rely on, Comcast says.

The new service can download a high-definition movie in 8 minutes, compared with 2 hours and 15 minutes for a standard, 6-mbps Internet connection at home. A TV show would take 20 seconds, instead of 7 minutes."

Are these numbers correct?

A T1 runs at 1.5 Mb/s so the quick math says that 105Mb/s divided by 1.5Mb/s is 70.  So the more than 60 times faster is a safe statement, assuming you get the full 105Mb/s.

The download speeds depend on how big the file is.  Using the calculator found here, I reverse engineered the assumptions:

5Gig_file_transfer

So the assumption is that the file is about 5 Gigabytes in size, and without any further information as to format, we think this is about right.
