NIC supporting Jumbo Frames 9000 MTU

[trueimage]

I'm looking to pickup 3 identical NICs and use 2 in Win XP and eventually Vista boxes, and one on my NAS (unRAID) in linux.

My current setup involves a Cable Modem into my WRT150N router running DD-WRT, and then Cat 6 running out to a Gig-E switch (Netgear GS108 v2) which connects via Cat 6 to the 3 PCs. The router also connects directly to a vonage box, PAP2 I think.

Now, the GS108 switch supports Jumbo Frames with a 9000 MTU AFAIK.

This is a list of NICs known to work well with the unRAID software:

# Intel PRO/1000 Gigabit Ethernet (At least one report of this being broken)
# Marvell Yukon Gigabit Ethernet
# Netgear GA311 Gigabit Ethernet
# Realtek Gbit - RTL8169S-32 chip
# D-Link DGE-528T Gigabit Ethernet

I was leaning towars the Netgear GA311NA, because I like netgear products and I assumed they would work well together easily.

However, I can't find anything on netgear's website or newegg or ncix etc that says it supports Jumbo Frames.

This really is a must, as I'm serving large video files and copying stuff around a lot (4.5GB - 15GB files)

I want to get the best performance out of my network so that I'm not swearing at it (as I am right now, it is too slow.)

So, does the GA311 support Jumbo Frames with an MTU of 9000?

If so, is it a decent NIC?

If not what is my best choice?

Thanks!

Here's a list of some jumbo frame capable equipment. It's not a complete list mind you, but it's a start. It states that the GA311 only supports an MTU up to 7500.

I know that SMC makes some PCI NICs that have jumbo frame support and are based on a Marvell chip. This is the one I've got and it supports up an MTU of 9000.
