Setup:
-All gigabit network equipment - no jumbo frame
-Server running 12 x 750Gig raid60 - Dual Intel Gig NIC
-Workstation using built in realtec NIC
 
Wow, that is amazing Madwand1, you are maxing out a gigabit line 🙂
Do you have jumbo frame enabled ? what kind of switch ?

Turns out that was with an on-board nVIDIA NIC on one side which doesn't support jumbo frames. The switch could have been a Dell 2716, D-Link 2205, or a combination of both of them, depending on what the layout was at the time (sorry, I don't recall exactly).

I don't think the switch would have made any difference, because I've done exactly this sort of test with them, and I haven't noticed the choice of D-Link vs. Dell having any material impact.
 
What are you guys doing to get those speeds???

I have a mix of gigabit adapters and I do good to see 60Mb\Sec and sometimes it drops to 15-20. I'm at default on all adapters. No jumbo frames. I'm using a D-Link green switch but had a Netgear switch but it was no faster. I switched to D-Link because the Netgear would not hold a 1g connection.

One thing I may have screwed was stapling my CAT5 to the baseboard. Staples every 8-10 feet can cause reflections but I wasn't thinking about that at the time.

*edit*
All drives are either WD Black or WD-7200RPM

Here's what you need:

1. Overkill on the storage speed. E.g. tuned RAID on both sides.
2. For Windows, Vista or later OS at least on the client side.
3. NICs working close to maximum speed -- typically on-board or PCIe.
4. Large test files. Small files can be slower.
5. Luck.

These Depict Regular Peer-to-Peer systems.

Computer with Onboard RealTek 8186 Giga NICs + $30 TrendNet Giga switch, No Jumbo Frames, CAT5e cables.

Regular 7200 Hard Drives that are connected to normal onboard SATA (No RAID) and can Read and Write at 80MB/sec.

Vista SP2 x64 on both ends, using FTP:

Pull

Push

No jumbo frames; both with onboard PCIe giga NICs, connected by a Procurve 1400-8G. Both PCs are C2D based, with identical HDDs used for testing. The average STR of the HDDs is ~87MB/s, with a peak of 113MB/s and a low of 52MB/s.
 
Similar setup... using the TrendNet green switch.

Vista Ultimate 64 bit to WHS

2x74GB raptors to a mix of HPs ex485 750GB, Hitachi 1TB, and 2 x 1.5 TB samsung drives.

I get around 79MB/sec
 
This reminds of of a problem I am having. I have two vista systems, one of them I use as an HTPC. It is connected to my main PC via a gig switch, which connects to a gig router - both dlink, using cat 5e cable. Total length of cable between them is ~75 feet.

I am able to get a steady 85 MB/s from my main PC to my HTPC, but from my HTPC to my main PC I can't do better than 30 MB/s. Both systems have disks which can sustain 70 MB/s or more on average and I am not using raid in any of my systems.

The NIC in my main PC is a Realtek 8111B PCIE (onboard) and my HTPC has an nForce NIC (Zotac 9300 Mini ITX board). I'm not sure why I can't get the same speed in both directions...not that it matters much but it just makes me wonder.
