How long will it take for a DVD to transfer over a Gigabit connection? (assuming everything is optimal)?

it takes solidly 6 hours…..
A dvd is 4 gigs compressed and ripped and a regular dvd is 6 – 9 gigs in space if you have a true gigabit ethernet and everything is optimized and their is not loss in packets or choke on the connection it could be done in as fast as a 30min to 1 hr.!
if you’re talking about 4.5 gb dvd over a 1000mb (1gb) per second transmission, then you’re talking about 4.5 seconds potentailly over a pure point to point connection.
Your system can’t buffer data that quickly though – and certainly can’t do disk activity that fast.
Your computer is probably liminted to 150mb per second read/write on the hard drive at best – and then you’re even slower reading data off an optical drive.
There are alot of variables that come into play.
Gigabit LAN = 1000 Mbps (Mega bits per second)
1000 Mbps / 8 = 125 Mega Bytes per second
Standard DVD-R = 4.7 Gigabytes = 4700 Megabytes
4700 / 125 = 37.6 seconds to transfer one DVD-R over Gigabyte LAN.
I’m sure the actual time would be a bit slower than that due to network overhead, etc. just like you never get 56kbps out of a dial-up modem.
I have no idea how many DVD-Rs it would take to fit the Library of Congress…..
Aaron is wrong…
A Gigabit connection is 1000 mega bits per second which when you divide by 8 is 125 megabytes per second which your computer could handle. He is right there are many things that can slow it down. Optimally running it can work at 125 MBps. which is about 38 seconds for a 4.7 GB DVD.
Good Luck HTH
