i'm too lazy/cheap to buy a gigabit switch for my network. still runnin' 100  :lol

MonMotha:
I honestly don't know how people put up with 100Mbps LANs, anymore.  I'm seriously considering upgrading to 10GbE. The only reason I haven't is that most of my storage at the moment is cheap and can't really go much faster than 1Gbps, anyway.

drventure:
Gigabit's cheap. I don't know much about 10gb so I can't comment there.

shponglefan:
Gigabit is definitely worth it over 10/100.  I recently upgraded my network to gigabit; turns out I just needed to replace one 10/100 switch and it cost all of $30 to do so.

However, I can't see going faster.  I find I top out my network speeds at about 40-45 MB/s (uploading to my NAS).  Looks like HD speed is the limiting factor.  I suppose if I had striped RAID on both ends, it would be faster, but honestly doesn't seem worth it at this point.

If you just replaced your switch, you should consider replacing the ethernet cabling with good quality Cat-5e.  I've done extensive testing with Gigabit, and find that usually when we hit 50MB/s, it's an issue with the cabling.  What's adequate for 100mbps isn't adequate for Gigabit.

You can get about 100MB/s to and from a consumer-grade NAS if you have about four drives.  If you have it in a RAID-5, it's going to really slow things down.

My own setup pushes 400MB/s, but that's with aggressive caching, look-ahead reads, a caching SSD, and a pair of log SSDs for writes, and 32GB of RAM pretty much devoted to the NAS.
