real life gigabit ethernet thoroughput

[homestarmy]

I would really like to move large files (1-4GB tv recordings mainly) accross my network. Where can I find info on how fast they would move over a gigabit ethernet connection? I could use two cards and a crossover cable, right? Would a gigabit switch be any faster?

Thanks!

expect to see 300-400 Megabits/sec depending entirely on how fast the computer is (hard drive, bus, etc)

A switch won't offer any increase over just nic to nic.

 

[homestarmy]

are there any other restrictions with gigabit vs megabit? lenth or quality of cable?

 

[spidey07]

just make sure it is cat5e or cat6. length is still 100 meters.

direct connect may be faster than a switch if the switch does not support jumbo frames.

If you want max speed enable jumbo frames in the driver before xfering.

I get double to tripple the speed of a fast ethernet connnection when using gig. If you are doing a lot of transers it should be worth your time.

would hd speeds be the bottleneck with something like this ?

1 - 4 gig files won't take that long with a normal connection so if you don't alreayd have gigabit, no need to go get it just for that. Should be able to transfer at somewhere around 5 minutes per gig or so... Just copy and paste and go to bed. 🙂

OK, time to do some math..

100 Mb/s = 10MB/s (easy figure to use, includes overhead, etc. and usually works).

1 GB = 1,000 MB
1,000 MB / 10 MB/s = 100 seconds, give or take a bit.


If you figure gigabit is 3-4 times as fast, you're looking at 15-20 seconds. That's theory, it HIGHLY depends on the sending and receiving PC's. If they are both modern, new PC's, you'll probably get 300Mb/s. If one is older, figure it'll top out around 150-200Mb/s.

That being said, gig nics are only a bit more than 10/100's, so it'll be cheap to try it out.
