Man back when i had my 10baseT network i rememberd how fast it seemed.. now a days i have 10/100 everything switched everywhere and the works, and its way to slow.. when im transfering like 30gigs of mp3's it takes for ever. Is there anything afordable that is much faster?
Fast Ethernet is too slow

I mean i guess it may seem odd, but really. Me and all my friends have fast, gaming rigs. Then when we decided to transfer something.... AHHH!!! GOD hurry up damnit.
Umm... hardly.
100MBit network is 12MB/sec max (in real life not over 10MB/s). Now remember that modern hard drives can spit data at 40MB/sec...
Gigabit Ethernet, on the other hand, can transfer up to 125MB/sec. Ok, little protocol overhead and line noise, youve got 100MB/sec transfers.

If you have the cash, I'll hook you up with one of the IBM Shark's (2TB drive) that we use at work...Its on a SAN (Fiber) and that 30Gb transfer can be almost instantaneous...of course its about $500K
500k lol
ok think about this, my friends cablemodem can download at .5MB/Sec he downloads gigs and gigs of stuff for me in a night, then to transfer it to me we only got like 8mbps max... if u can get a connect to internet for 40$ a month that fast, there has to be something afordable? heh, I remember seeing NIC's that use 2 fiber cables, that were very cheap like 70$ or something a card, but i bet the cables are very expensive..
how much is gigabyte hub/switch

You aren't going to find a better solution than a 10/100 switched network, for your cost/needs.
You can bump up to gigabit, but the cost for it would definitely not be worth it to just transfer MP3's.
There is NO WAY that your friends cable modem will ever match what your HD's can pump across a 100mb switched network.
The max speed I've ever seen a cable modem hit was 1.5 megabits/second. That is ~ 187k a second. 1500/8 = 187.
A 100mb network will be able to pump across 12 MEGS per second, provided there is no bottleneck such as disk performance, lag, collisions, stack overhead, ect.
If my math is right, at highest performance, a computer should be able to pump across 30 gigs in about 40-42 minutes. 12x60x42 = 30240 or, 30 gig.
My suggestion, transfer less data, or deal with it.

no he can download 500 kbytes/sec AT&T took some limiter off his modem
thats 4megabits/sec
I never got 12MB/sec on my network and its switched.. do the cards have a major affect on performance? mine are D-link

Even if he could pull down 500k, then he's still a fraction of what a 100mb network would in theory be able to reach.
Like I said, there are a lot of factors that come into play - quality of nic, quality of switch, quality of cabling, disk I/O performance, among other things.
I the host(person w/ the MP3's) only allowing one user to access at a time? If you have more than one person pulling down at a time, you are going to notice a significant drop in performance if so.
Still though, bumping up to gigabit wouldn't a worthwhile investment unless you guys are all running some SCSI drives w/ some massive I/O performance.
Always keep in mind - you are only as fast as the slowest link.
If one of the two computers has a slow part in it, then you will only transfer as fast as that computer can push/pull the data.

Also, if I was your friend, I wouldn't get too used to having 500k downloads. Eventually the neighborhood will catch up to him and he will be down to 200k or slower.
500k sounds extremely high, even for a cable modem.
THe cable modem that I had from ATT@home maxed out at 1.5 megabit. I know that most of them in the area around Cedar Rapids, IA are the same as well.

Also, I don't have enought conclusive evidence to say one way or another what impact a "cheap" NIC like a Linksys or a D-Link would have on performance.
Most of my file transfers are under 500 meg, so that amount of time isn't significant enough to notice a difference between a 3Com or a Linksys.
Maybe someone here could provide better information, or some numbers pointing one way or another.

Yes your right,
You understand my situation right? Not that he's as fast or anything, just an example. I transfer almost 100gigs a month, every week i goto a LAN party or at least friends house, and we always have gigs of stuff waiting for eachother.. and it takes way to much time to transfer... way to much I'd be satisfied with like a gig in 10min or something, but when your spending hours just transfering when you want to play games and stuff its silly.

With switched 100/Full duplex ethernet you should get about:
10 Mbytes/sec
600 Mbytes/min
6 Gigabytes/10 min
Sounds like a network problem or possible limits of your hard drive. Make sure your speeds/duplex match up with what is on the switch between source and destination as this can cause serious performance loss.
If switch is set to auto negotiate then set the card to auto negotiate speed/duplex.
If switch is set a speed/duplex then you must set the card to the same
NEVER SET ONE SIDE OF THE LINK AND LET THE OTHER SIDE AUTONEGOTIATE. Either auto<--->auto or force<--->force. A duplex mismatch will cause dropped frames and retransmissions, your TCP window will NEVER get much higher than 2 kbytes. Also MS networking is notorously slow with HUGE overhead. USE FTP.
Check these things out. Also if you wanna take the network equpiment out of the equation then use a cross over cable between two computers only and set both cards to 100/full.

never thought of trying ftp LAN, ill have to try that.
everything on my network is full duplex,
with MS networking max ive ever seen (using DU meter) was about 9mbps, witch is like about double what my friend downloads heh.

WOW, 9 megabits/sec. That sucks.
When you say the network is full duplex are you saying that you have set the switch ports to full duplex and the NICs as well?
Try the cross over cable between two computers and take the switches out of the picture.
What protocol are you using? How are the files being moved between PCs, windows networking and shares? What OS are you running? Any other protocols bound to the nics?
