What throughput are you observing?

That's close to the range I observe on my DNS-343s ~10-14 MB.

These speed is more like 100Mbps connection, gigabits should be much higher like 20 to 30MB.

Are you all talking about megabytes or megabits? 14MBS is about 140mbs

I am getting around 60-65 mbs (megabits/sec).  

Configurations is as follows:

CABLE MODEM > CAT5 CABLE > WNDR3400 ROUTER > CAT5 CABLE > DGS-1024D SWITCH (previously used DGS-2208 with about the same results) > CAT6 CABLE > DNS-321's and other individual devices.  PC has gigabit NIC card.

Check all your cables, make sure you have good CAT6 wiring.  I like putting a switch ahead of the Router.  I only have the DGS and an OOMA Hub (VOIP) plugged into the router.

It's pretty clear when one state MB it refer to Megabytes (notice the uppercase B). And 14MB is not 140Mb but 112Mb ( 14MB * 8 ).

BTW, for gigabits (1000Mbps) connection, CAT-5e cable is good enough.

I have used the 1.03 firmware update and it is just total SHI* for speed. I would not get over 7-8MB/sec with 1.03 sometimes slower no matter what configuration I would use jumbo on 3k 9k nothing improved speed.

 I went and flashed back to 1.01 and now get 14MB/s steady while not real gigabyte speeds I can notice the difference. I went through every configuration and I get best speeds on Auto with no jumbo frames.

My config is

DNS-321 v 1.01
Netgear GS108T Gigabyte Switch (Network)
Linksys WRT54G with DDWRT (Internet)

so from what everybody is saying i am not going to get Gigabit speeds out of it just have to be happy with the 10 to 14 MBs thanks everyone for the reply i thought i was doing something wrong. but seems like its dlink that has done something wrong because 10 to 14 MBs is not Gigabit speed no where close.i have a linksys e4200 and 2 linksys Gigabit switches 10/100/1000 and i usually transfer at 90 to a 100+ with everything else in the house. so once again thanks

Although you MAY expect greater speeds on gigabit ethernet, it's important to recognize that anything exceeding 100mbps is, by definition, gigabit - now - it would be nice to see 400+ mbps, it's important to recognize what you're dealing with, a low cost, low power consumption NAS, and the reality is you're not going to get it.

The bottleneck is the NAS itself.

I have read that it is the processor in the 321.. 15MB (15*8= 120Mbs) is in the most common range or xfer speeds I have read on the forum..

I did indeed see a speed increase when I went full Gbs network.. but it isnt anywhere close to actual 1Gbps. 

The xfer screen shows in Mega Bytes, 1 Byte is 8 Bits so convert to network ratings, multiply by 8 you get Mbs..

There is a bug in the samba version used in the 1.03 firmware which causes slow transfers relative to other firmwares. Not DLinks fault, but they should release a new firmware with a new version of samba in it without the issue.

You can either downgrade the firmware to 1.01 or use a fun_plug and run a different version of samba.

The hardware in the device is slow. Over gigabit you shouldn't expect more than 15MB/s
