The Graveyard - Products No Longer Supported => D-Link Storage => DNS-321 => Topic started by: ddasilva99 on June 21, 2010, 08:09:01 PM

Hello,
I purchased the DNS-321 this evening and I plugged in two WD 2TB green drives running in RAID 1/EXT3 configuration. My NAS is connected direct to my Marvel 1Gbps NIC via cross cable. I have configured my NIC and NAS to run jumbo frames, 9K.
When I transfer a file it usually transfer between 9.3-10.2 MB/sec (as stated by Windows 7 File Transfer dialog).
I feel this is unusually slow since they are new drives and I have configured jumbo frames. Could someone please advise if I have done something wrong?
Thanks,
D

Probably not, but you should be able to get it up to maybe 13-14. There might be some other issue in the network throttling the throughput to 100mbit, which looks like what you're getting.
-
Its probably the drives. If the model number ends in EARS they are the WD Advanced Format drives which D-Link doesn't support.
-
The drives wouldn't explain that slow a transfer.
-
I'd like to jump in here as well. I have the DNS-321 hooked up to my D-Link DIR-655 All supposedly Gigabit ports. When logged into the 321 the speeds it says it detects is 1000 so gigabit. Yet when my PC is copying files to it, i'm only getting 5~6Mbps copying huge files over. WTF?
I enabled the 9K jumbo frame thing and it's still in this range 5/6/7Mbps.
This is total garbage.
-
I get the same results no matter how I configure my router, NIC, switches, and other equipment.
For some reason many of the NAS devices available have atrocious networks speeds.
It would appear that among the DNS-321's many other faults, this is also one of them.
-
I'm totally f-in confused now.
When I FTP upload to the NAS I now get like @ 15~20Mbps UPLOAD.
But when I try to download I'm only getting 3~6 Mbps? DOWNLOAD? Why the hell is this slower?
I tried turning off JUMBO Frames on both my NIC card on my PC and disabling it on the NAS device. Same thing. Enabled it again on both and same thing.
I don't get it? Does anyone who has the 323 have these issues?

Anyone? It's SLOW still copying from the device. < 4Mbps. Writing to it is faster???
-
Are you using FTP to transfer the files internally? Have you tried SMB? I wonder if it's worth connecting directly to the NAS with a network cable and see if you still get slow speeds. You might find your network is the issue?
-
SLOW SLOW SLOW this is gigabit? Regular Ethernet even seemed faster! Even my DIR655 has an extremely slow config page. I'm really starting wonder about D-link.
-
If you're on a totally gigabit ethernet network set the DNS to 1000bps not "auto". Something about using the auto speed selection slowed it down. Still, I'm not getting above 12MB/sec transfers in either direction.
-
You need to spend more on a NAS to get the performance you expect.
-
I will return the 321 and buy a USB 3.0 box.
NAS and locally attached USB are very different things.

I have a DNS-321, DNS-323, and a Synology DS209. There is a significant difference, here's my benchmarks.

i Just got the 321 today along with a seagate 2tb 5900 and I'm transfering some movies from local hard drive to the 321 at 15.2mb per second.....
-
Wow - I just configured to RAID1 and thought I would see how performance is doing. Copying a 3GB file to the NAS did just over 5Mbps, copying off did over 11Mbps. Smaller files copied from the NAS at 15 Mbps.
That is disappointing for a GB LAN. At least streaming from the NAS is faster.
-
How can I measure the transfer rate?
I just rec'd my 321 yesterday (with two 1TB drives). They are the Black Caviar (WD10EARS) drives. I initially confirgured the 321 as Raid 1 with Ext 2 format. I then copied my media files onto it. I was able access all files and play 720p video without any issue.
Then after finding this forum and reading a few posts I decided to reformat as (2) separate drives. I'm in the process of recopying my files and the performance is terrible. Shouldn't this be faster than RAID?

Did some poking around the web this weekend... Looks like 15MB/s is the best you can expect on this device. One of the clearer explanations I found was here: http://www.krazyworks.com/gadget-review-dlink-dns-321-nas/ (http://www.krazyworks.com/gadget-review-dlink-dns-321-nas/). Now if only I could figure out how to get to 15MB/s from the 6.5 that I have right now.
