The reason I said you "goofed" is that there is no word "intra-LAN" used
in networking. The closest (common) word would be "intranet", meaning
precisely what you wanted to convey with your word choice.

Yeah, my comment was more directed at Curt, to explain that while disk
I/O "may" come into play, it really will only do so if the drive's
sustainable speeds are significantly lower than that of the network
link.
