No problem providing more info. Just remember, you asked for it!
Originally I wanted to create my own router using an old box I had lying around, but it was suggested by GregN that running both a Router and NAS on the same box would probably present a large security issue. So, after deciding it was best to split the project and focus on a NAS/Web server and simply buy a wireless router/switch combo, I ended up here.
At the moment, I have everything running in one computer. All my storage drives are in the same system that I use for browsing the web and playing vidya games. My goal is to centralize all of my files in one place so that I can access them on any computer in my house. I've started to spend a lot of time in the kitchen cooking, so I have a computer there. I also have an HTPC in the living room, an old computer in my bedroom that simply streams content to play on a TV, and of course my iPhone. My goal is to be able to access my media anywhere I go. Like carrying your file server around with you.
Although this has worked pretty well so far, it makes my computer REALLY damn loud and it generates a freaking ton of heat. This computer is also in a small den-like room, and although it's generally comfortable, once that video card gets cranking all that heat adds up and you end up with your very own unintentional sauna/environmental catastrophe.
Sadly, this environmental offense is probably less of a concern when you consider that I'm running all this solely on WINDOWS. I know, what a sacrelige. Also, I've been planning to get back to working with Linux and I figure that this project will help me do it. So, I'm giong to create this NAS running (probably) Ubuntu Server, loading it up with all of my drives, and then every computer wired or not will access this beast through the wireless router. So, it's both functional, and a fun little project.
All of that considered, the main function of this router will be networked DATA SHARING, so both wired AND wireless throughput are of utmost importance. Looking at the charts I noticed that the ASUS seemingly had the highest throughput, but I later realized that this is partially skewed due to the gigabit WAN to LAN speeds. I don't have gigabit internet nor is it available (I wish it was) so I think a standard 100mbps port will tide me over on the WAN front.
This will be replacing my AWFUL D-Link DI-624 that won't even allow me to run Steam (even with correct port forwarding set up) and stutters every time I try to stream a BluRay movie over wireless at 802.11g speeds. Also, I will probably end up flashing the firmware with DD-WRT just so that I can get some better QoS packet managment as well as bandwidth monitoring features. I want to know exactly how traffic's moving around the network.
Also, it probably bears mentioning that in this NAS I'll have a couple of 2TB low-RPM archive drives and some WD Caviar Black 1TB drives in a RAID setup for files that I frequently access like music/movies/tv episodes. I can transfer files at 100 MB/s from one WD Black to the other internally, and I want to try to retain this speed as best I can over the network. I realize that things will be a bit slower over wires and a few client intermediaries, but I don't expect TOO MUCH of a slowdown.
