Guys, post your speeds and settings that matter.

DNS-323
DIR-655
Marvel gigabit both with Jumbo Frames at 9000
Core2Duo 8400@3600
4GB Gskill 8000

Not bad - push the file size up to 1 & 2 GB and see what you get, typically it'll be faster than what you see at 500MB.

Now - although you've listed what's at the other end, you're missing the critical info - like what drive subsystem does it have.

[pbls]

The drive from i run nastester was a WD 640GB.

[fordem]

The drive subsystem involves a little more than just the drive and the capacity itself - is it SATA-I or SATA-II, is it RAID, even the time it was last defragged (yes it makes a significant difference).

I've seen read speeds similar to what you have (just over 30MB/sec) and write speeds a bit faster (around 24MB/sec) when running NASTester on my IBM xSeries server with a Maxtor 2x250GB RAID1 array - however, after I switched the server's RAID1 array to a RAID5 using 3x250GB Seagates the NASTester read figures took a serious nose dive, due to the "RAID5 write bottleneck".

Sooner or later you'll come to realise that the throughput numbers are purely academic - it's realworl throughput that makes the difference.

Try transferring a single 2GB file and then 1000 x 2MB files - same volume of data, but I'll be that the single large file transfers a heck of a lot faster

Y is no 1 posting! is this a dupe thread?
I want some specs to compare 2!!

DNS-323 w/2x WD10EARS in RAID1

1024MB File: Avg. W. 15.62 MB/s, Avg. R. 29.72 MB/s

1 thing..is NASTester spec'ing bits or bytes? I'm guessing it's bytes. Rite?
Bits are small 'b'...and NASTester is showing BIG 'B'.

Correct!

By the way - thanks for reviving the thread, there's a forum member here who has doubts as to the capabilities of the unit, your numbers should certainly interest him - they're quite impressive - this is the first time I've seen someone approaching 40MB/sec.

[gunrunnerjohn]

I have no idea how they get those numbers from the DNS-323, I've never seen them here.  Here's a set of tests from a local drive, a Synology DS209, and the D-Link DNS-0323.

Did you changed anything on the software of the box to get those speeds ?

[gunrunnerjohn]

Personally, I'm not at all impressed with the speeds I get.  Look at the previous benchmark!  My speeds are pretty lousy, which is why I now have a Synology DS209 for my main NAS.

My speeds are almost the same as yours for both NAS.
I would also like to know how they squeeze those high transfer values out of the DNS.

[gunrunnerjohn]

I'm at a loss how they do it.  I have one clue, it could be my SOHO gigabit switches.  I also notice that my upload/download speeds to/from the Internet are affected by the switches.

I get this when I connect directly to my router with this computer.



This is what I get when I connect through my gigabit switch, and I've tried three different switches with the same result.



I'm thinking that something about these cheap switches is hammering my upload speeds, since that's the only variable.  I just wondering if I'm not seeing the same thing talking to the NAS boxes.

[ttwong]

I've been searching for solutions for days and have not found any solutions.  I have my 323 connected to a Linksys WRT610 router, with Cat 6 cable.  I use to only get 7-8 MB/s upload speeds, downloads are about double that, but recently its gone down to about 100 KB/s.

I have two 1.5 TB 7000 rpm Seagate drives in a Raid 1 configuration, running Vista Ultimate 64 bit.  I'm also using the latest firmware on the 323.

Thinking that the drives were fragmented and/or had viruses, I backed it up and reformated the drives.  No change in speeds in Raid 1.  I then tried JBOD, Raid 0, and independant volumes...no change.

I then played with the settings, and when I went to Jumbo Frame 9000, and 100 MB instead of 1000 MB connection speed, my upload speed has gone up to 400 KB/s.

I'm so frustrated, I'm considering getting another NAS.  Any ideas?

Thanks,

Terrance

[gunrunnerjohn]

Well, 100mbit doesn't use jumbo frames, so those settings are mutually exclusive.  If you get more than about 10-11 mbytes/sec either way with 100mbit, something is wrong with the benchmark!

As I mentioned previously, I picked up a Synology DS209, my speeds are posted previously in this thread.

Running a 1000MB file write on drive I: 5 times...
Average (W):     25.07 MB/sec
Running a 1000MB file read on drive I: 5 times...
Average (R):     45.26 MB/sec

Conversely, for the same test with the DNS-323, same switch from the same system I get.

Running a 1000MB file write on drive J: 5 times...
Average (W):     10.27 MB/sec
Running a 1000MB file read on drive J: 5 times...
Average (R):     16.47 MB/sec

 I'd love to see the speeds others are reporting in these forums, but it's never happened.  I did get 13-14mbyte/sec upload speeds with a pair of 7200 RPM 500G drives in RAID-0 when I first got the DNS-323, and the read speeds were a bit faster as well.
