How can I connect my DNS-323 to a 100mbit modem/router and get gigabit speeds to it and my PC? Can I hook up a gigabit switch to the router then connect my PC and the 323 to it?
Any help appreciated.
-
Connect a gigabit switch to the router, connect all the network devices to the gigabit switch. Problem solved. :)

If you have a 100mbit connection, you're router should already have a gigabit switch on it. If it doesn't I'd consider getting one.
-
I'm sure he was talking about the ports on the router, not the ISP service.
-
also, you'll never get/reach gigabit speeds with the DNS-323, even if using it back to back with the end device.
i believe the maximum speed reported here on the forums was about 122mbps.

If network speeds are what we're discussing, then I've actually seen as high as 400mbps to/from a DNS-323. If file transfer speeds are what we're discussing, then the number drops to around 250mbps.
As far as I'm concerned, once you cross the 100mbps threshold, it's gigabit speeds - can you transfer 122mbps on a 100mbps LAN?

never said you could, was just pointing it out there for him.

Never say never ;)

It depends which protocol you are talking about, I've made some iperf tests with it and was able to reach 230 Mbits unidirectionnal (bi-dir is really bad, sureley because of the network cables)
After that, my cables are only CAT 5 certified and I've used the chipset of my motherboard for network connections, so I think I should be able to go further but I'm satisfied of that perfs.
Remember that Cat 5E cables are certificed for 350 Mbits, they may be able to handle more, but that's pure luck.

Actually theoretical maximum is 128 MB/s not 122 mb/s, in essence he is probably meaning that 122 MB/s is the highest he has seen on the forums reported. The BIG DIFFERENCE between MB and mb/Mb is capitalization of the second letter, Uppercase is bytes and lowercase is bits and there are 8 bits in a byte. And no you can't exceed a 100 mb/s on a 100 mb port, you need a gigabit router or switch, with the gigabit devices connected to it to even come close to the theoretical maximum of 128 MB/s ....thats Megabytes btw... :)

Just a suggestion - at least familiarize yourself with the topic being discussed before chiming in ...
He says (and I quote) "i believe the maximum speed reported here on the forums was about 122mbps."
To those of us who've used a DNS-323, there is no doubt whatsoever that he does in fact mean 122 megabits/second - the idea that a DNS-323 might be able to somehow achieve 122 MegaBytes/second is - quite frankly - ludicrous.

I had a similar problem. The router was gigabit but often would not transfer faster than 100mbit speeds. I connected everything to a gigabit switch instead and then one connection to the router. I now get 35-40MB reads and 15-20MB writes on the DNS-323. Cat6 cables all the way. All connected properly and tested. Was previously no higher than 12MB reads/writes. It still on occasion gets slower.

In your dreams! ;)

Please bear with me, I am new to this.
My current setup is like this:
Cable Modem> Router> Giga-bit-Switch> Everything else (2 Computers, D-link 323, Xbox-360)
With this setup I am getting a Read write speed of 10MB/sec from 323. All cables and router are gigabit.
Your consensus it to have setup like this for faster speed?
Cable Modem> Giga-bit-Switch> Router>Everything else (2 Computers, D-link 323, Xbox-360)

Nope, your configuration is correct. You can't put the switch in front of the router or you'll have no file sharing.

I have a CAT5E home network with four machines all connected to the same Gig switch (Linksys SD-2008) and the DNS-323 is also on that same switch. The best performance I have ever seen on mine is ~140Mbps (not MB/s) and that was observed from Task Manager on a windows box. I am running a pair of Seagate 1.5TB drives mirrored in RAID 1.
Not bad for a little Linux box, IMHO. Yes, there are faster solutions out there and of course windows is not the faster either for file transfer.
All in all, my DNS-323 is on its second set of drives in as many years and performs reliably and with decent performance.
-
That's the performance I get as well, but I didn't like the speed so I got a Synology DS-209, must faster, like about 3x faster. :)

I just purchased a second DNS-323, ran some tests and something seems screwed up.
Here is my config
1st DNS-323 (NAS1):
Connected with Cat5e to Netgear Wndr3700 - Router indicates the connection is 1000
2x WD 5200 RPM 1.5 TB drives in Raid 0
Using the NFS Addon (does not allow to set
2nd DNS-323 (NAS2):
Connected with Cat5e to Netgear Wndr3700 - Router indicates the connection is 1000
2x Hitachi 7200 RPM 2 TB drives in Raid 1
Laptop:
Windows 7 Ultimate, Intel ABGN4965 connects at ~130 Mbps to the Wndr3700 on 2.4 GHz
PC:
Windows 7 Ultimate, Dell Wireless 1505 connects at ~270 Mbps to the Wndr3700 on 5 GHz
Uploading a 2GB video file from either the PC or Laptop to either of the DNS-323 I get speeds around 6 MB/s
I decided to copy all the data from the older DNS-323 (NAS1) to the newer one (NAS2). Using the web interface (which in the back is using smbclient) I copied a folder which contains a lot of video files, and the copy was very very slow
So I mounted the folder using NFS and using rsync to copy files from one to the other I was getting a max throughput of around 3 MB/s
Using rsync via ssh to copy from one to the other I was getting a max throughput of around 1.5 MB/s (which probably has to do with the encryption overhead of ssh)
Using just regular copy across SMB or NFS mounts the throughput was almost the same at around 4.5 MB/s - no gain using NFS over SMB
Using multiple connections (more than one file being copied at the same time) the aggregate speed is the same (each individual connection slows down) - around 3 MB/s
Using FTP from one DNS-323 to another I get around 4.5 MB/s for one transfer
Using multiple FTP connections, each connection maintains around 3 MB/s up to four simultanious transfers (after which it starts degrading) hitting a ceiling of around 12 MB/s
So for curiosity's sake, I reran the smbclient copy (as the web interface would have executed it) and it seems like the smbclient copy is maxing out at around 1.5 MB/s
Summary:
Copy via SMB from PC/Laptop to either NAS1 or NAS2 - 6 MB/s
Single stream unencrypted - rsync - 3 MB/s
Single stream encrypted - rsync - 1.5 MB/s
Single stream unencrypted over SMB or NFS - cp - 4.5 MB/s
Single stream FTP - 4.5 MB/s
Four FTP streams - ~3 MB/s each totaling 12 MB/s ceiling
Wierd...
