I primarily bought this device as a dlna nas. I feel the need to share my experiences here as i just set up a drobo for a friend recently and the experience was much better.
I have these devices on my network
apple tv with xbm
ubuntu linux with myth
ps3 2.51 firmware (dlna)
2 x xbox 360
macbook
macpro quad xeon
vista 64 ultimate (another quad xeon machine)
onkyo 906 receiver (dlna)
The good:
mountable from afp,smb and nfs
Cheap
fairly easy setup
runs linux and open source code provided
dlna/upnp (fuppes), itunes and torrent clients.
decent backup software for windows
The bad:
no way to tweak the linux configuration -- promise: look at what drobo did with drobo apps.... it's a great business model to promote your device!
The Drobo model is ok. We will have a Dev Kit for the community that will require an NDA. We are headed in two different directions as we move towards digital downloads and other services. The Drobo model is just open which is ok but their Drobo Share is overpriced and also supports limited features and services. Good Luck.

documentation is poor
Documention is getting a rewrite and I will be supervising. Yes, it is poor.

Slow - 4gb file sometimes takes 1 hour to copy even with jumbo frames
Something is wrong with your configuration. You are synced at 1000 Mbps? What GNIC? What Switch? I am easily copy 4GB in a few minutes not hours.
afp keeps shutting down for no reason
Resolved in SR5 FW. Will be posted tomorrow. If you cannot wait, send me PM for access.
afp displays 5 separate welcome messages
In SR5, welcome message can be customized. Leave it blank for no message.
nfs does not work from my mac
NFS support is meant for Linux OS and is not tested under Mac. SMB and AFP are supported under MAC
you need to connect to 5 different shares to do what you want.
itunes server does not recurse directories, everything has to be in one folder.
New version is now build on Firefly. Tested with 75GB of music with sub directories. Now supports Video playback. Email me for beta version. Will be posted in the near future.
crappy software (smartnavi) to control the torrent plugin, why could this not have been built into the web interface?
The idea is to move features out of the browser as it everyone knows how to or wants to open a browser everything to access files and makes changes to configuration. The BT applet will be seeing some new features and enhancements in the future. SmartNAVI on the other hand is better than what any other vendor offers. You can directly access shares, change permissons, manage users, load Plugins and more. You can also use PASM if SmartNAVI is not to your liking.

My ps3 keeps telling me "the media server has disconnected dlna error 2110" and i cannot stream video for longer than 5 minutes before it disconnects me, i've installed fuppes (same dlna server as the 4300) on another linux box to see if it was a problem with my media/network , and it is not fuppes it works great just not on the 4300
The NS4300N and PS3 are DLNA Certified devices. Unforunately in some configurations things do not work as well as expected. I use the PS3 all the time for streaming never see the message you reported until you have a large library. The large library issue is addressed a new BETA version of the Plugin. Send me PM for Plugin. If your library is not huge and has issues, what other devices do you have on the network (UPnP or DLNA). I am chasing down an issue with the DLNA stack used on the Samsung TV's as it can cause other devices such as the PS3 to constantly disconnect from the NS4300N. Send me a PM to discuss more.
my onkyo randomly gets disconnected while trying to play back 320mp3
More details such as configuration (playback devices, etc).

randomly needs to be power cycled because the power button, web client and smartnavi stop responding
You are on SR4 FW? Please check your event log? Any Bad Sector Loggin Errors? If so, more than one disk? If unit becomes unresponsive it is generally due to File System Errors and errors on multiple disks which can something corrupt the File System. Again, PM me to move forward.
My advice to anyone considering purchasing one of these as a dlna server to stream video is to stay away for now till they get the firmware figured out, if you are hot to trot on a dlna server, get a drobo and droboshare. I'm now considering getting a drobo/droboshare as it works as advertised.
