What bothers me is i always used to have 10-12mb/s write and fast reads 20-30mb/s
and i lost it somehow
not sure if its the new 2.03 firmware or something else that caused it,
any1 can help or had same issues?
-
Same here...
(starting to think that with such a bargain, we´re just getting what we paid for...)
My WD 1TB live gets ~45MB W/R..... ::)
-
simc84, if you had higher speed before what has changed in your network setup?
As an example, we had a client that sent in a report that their network had started to crawl. On inspection we found that one of the cables had been put under one of the legs of a desk - to stop the cleaner moving it - and as a consequence was partly cut through. Replacing the cable brought the network speed up to normal.
I am not saying this is your problem, just that everything needs to be checked.
-
added some additional devices
anyhow, will replace to a brand new cat6 cable on both ends
and disconnect all the devices from the switch except these 2 ends and report again later
-
with WD live i manage to get a solid ~45 MB R/W.
Using the same cable that connects to WD live and...tadaaa: ~30w/10R
This NAS should give at least ~30R/W out of the box...Shouldn´t be necessary to tweak around...

same or even worse results here >:(
also just upgraded nas fw to 2.03 and bought gbit switch to speed up the home network speed - to no avail
nas seems to be the bottle neck in terms of read speed
-
You can't compare apples to oranges...
The DNS 320 has:
CPU 800 MHz
128MB RAM
Some WD NAS have 256MB RAM. So you need to compare all specs.
Yes, the memory does make a difference.
You have to also factor if you have a GB network all across, such as GB switch, cat5E or newer, GB NIC on laptop or server, etc.

I think, something went wrong with latest firmware upgrade :(
Before upgrade, I used FW2.00 and had read speeds about ~35MB/S (2x SamsungF1 1TB in RAID1 and NAS of course connected to gigabit network) and I was relatively satisfied for about year or so.
Last week, upgraded to 2.03 (mainly because of time and fan issues) and now I noticed, that read speeds from NAS lowered to 11 MB/s, whereas write speed to the NAS is relatively OK at about 25 MB/s.
Tried resetting NAS to defaults, messed with samba's socket options (mentioned in discussion http://nas-tweaks.net/148/transfer-rate-and-networkperformance-of-the-d-link-dns-320/ ) disable fun_plug, I'm not using FTP, P2P or any other CPU hungry services ......... but nothing helped, it is stil sooo slow.
-
I had the same problem. But reverting to 2.02 firmware fixed it. As mv_cz said there is something wrong with latest firmware

Benchmark cancelled.
canceled the benchmark because results were evident :) un fortunately i dont have spare time to dig deeper what causes this behavior
-
Many thanks for your test. I tried reverting back to 2.00 but this didn't work - so going back to 2.02 is possible?
And is it true that fw 2.02 has problem with file copying? Maybe that's the reason for this behaviour. D-Link "fixed" samba's problem resulting in speed drops :-\
Now i don't know, whats better: slow and safe (2.03) or speedy NAS (ehm, standard system performance :-)) with file system problems (2.02)? :-(
-
reverting to 2.02 is possible on mine it went without problems and the settings and data are still there :)
didnt noticed any problems with file copying. i have tested it also in windows explorer with files up to 15GB big.
-
more to that it seems to me that it is realated to cpu / mem beeing overused in 2.03

Reverted back to 2.02, Stock (no fun plug).
And speeds are now acceptable and similar to xsnailx benchmark....
Product reached EOL, now firmware 2.0(>3) will be hard to appear and solve the slowliness issues.
-
Me too, I've downgraded to 2.02 and read speed is relatively ok without fun_plug (about 25 MB/s which is still lower than with 2.00 but OK). With fun_plug active, it's somewhat lower at about ~17 MB/s and I'm using fun_plug because of Twonky DLNA server, which is idling at that moment.
Tempting to try 2.04b01 but there is no changelog available.
Maybe it's time to upgrade and buy another NAS. In my opininon, not much will be upgraded, it is getting slow a still a lot noisy. I've figured myself, that this has something to do with gigabit connection. Even with harddrives powered down and with no activity, the fan is spinning. System reports temperature about 40C, harddrives (when active) max 35C. The new DNS-320L is not faster (don't know why, it has 2x more RAM), it has simmilar small fan ::) And DNS-325 is a bit expensive - at that price, it's better to go with Qnap/Synology etc..
-
FWIW - the slow read performance in 2.03 occurs if accessing the DNS-320 via NFS as well - I did a crude test copying a large file (DVD .iso image) from the NAS; I couldn't get more than 8-9Mbyte/sec average for both NFS and CIFS mounts from the same Linux PC.
Went back to 2.02 and getting approx. 35 to 40Mbyte/sec for the same file copy (CIFS very slightly slower than NFS). So I shall be staying with 2.02 for now and hoping that the "0kb" issue stays away...
