Networking question

need some advice here. Just purchased a Dlink DIR655 gigabit wireless N router with the intention of faster file transfer.

my network consists of the following, MacBook (wireless N), iMac (hard wired 10/100/1000), MacMini (hard wired 10/100/1000 used for media centre only) GCC Tech network printer (10baseT) Plextor PX-EH400 NAS(400Gb HDD 10/100 with two 500Gb USB2.0 WD MyBook HDDs connected to it for movie storage.)

The "bottleneck" in the network is the NAS, just wondering if I'd be better off replacing the NAS and attached USB drives with FW or USB2 drives connected to either the iMac or MacMini and leaving such machine on all the time with sharing turned on. Thinking being FW is 400Mps and USB2 is 480Mps compared to 100Mps over the network.

On an off topic, can FW drives be RAIDed? ie striped?

You may wonder why, well I'd kinda like to be able to have the ability to watch at least two movies on separate machines at the same time. Gigabit and all.

Most NAS devices use an ancient implimentation of Appletalk (i.e. classic appletalk ala netatalk). This is _much_ slower than what OSX uses (appletalk over tcp/ip).

Couple of suggestions to try. First, try connecting to your NAS with smb:// protocols instead of afp:// .. you may be surprised at the results. If that doesn't work then you will probably be better off with the drives attached to a machine for sure.

Lastly, you can try doing some media streaming if you want to get really geeky I use VLC ( http://www.videolan.org ) and do realtime transcoding to UDP streams targettted at the IP address of the machine in question. I can actually get away with doing an decent quality UDP stream (DIV3 video @ 384kbs, MP3 audio @ 96kbs) over my VPN and high speed internet access, and watch videos from my media server from remote locations all the time Going with this approach you could potentially run much more than 2 streams without bottlenecking (well maybe at the CPU of the streaming server hehe)

HTH

Oh .. and yes FW drives can be RAIDed n OSX (striped, mirrored and spanned).

smb://computername/sharename
Supposedly it can take up to 10 mins for smb share to show up on the network.
SMB has to be actived in the networking pane...

edit I should have typed this: first press command k to open the go to dialog.
then do as above or like this:smb://ipaddress/share name

Actually you don't need to active smb/windows networking in shares to do this, I was talking about connecting to the NAS device with smb instead of afp.
