Hi,
When copying from a PC to a DNS-323 over gigabit ethernet (distance is a few feet and switch is local), what file transfer speed do people get?
On the DNS-323 LAN setup page, I see it showing "Speed 1000 Mbps".
On my PC, it shows 1.0Gbps connection speed.
When I transfer a file, it gets around 12MB/s, which would appear to be quite slow to me. Is this slow or average?
Thanks,
RW

1000Mbits and 1.0Gbps is the same so you are ok there. writing to the unit is slower the reading from it. most people here get about ~20MB/s - ~25MB/s reading and ~10MB/s - ~15MB/s writing on a Gbit network. theses numbers can differ due to a lot of factors like network and/or drive proformance on both the NAS and your computer etc..
12MB/s is not bad for this device and seems to be working normal.
-
The transfer rates are dictated not only by the network speed, but also the devices you are transferring from/to and how fast they can read/write.
I believe the packaging says up to 15~20MB/sec (I've had my DNS-323 over two years now, and the packaging is long gone), since then D-Link has added jumbo frame which potentially improves the throughput so it's should be a little faster than that, assuming the other end can handle the speed
I've got a couple of different computers - one, a server can write to the DNS-323 at close to 15MB/sec and read from it at just under 30MB/sec, but my desktop (gigabit equipped), which has the same processor and memory as the server can't manage anywhere close to that - maxing out at a miserable 6MB/sec.
Your 12MB/sec isn't the fastest, but it's also not the slowest.

I have been clocking the time to copy 13.8 gig of files to find the speed, which is 6.35 Meg/Sec.
Is there a utility which would make the job easier as I fool with the NIC speeds?
-
this http://www.bandwidth-meter.net/ could be useful :)
-
Search this forum - I have posted a link to a utility called NAStester which was written specifically for testing read/write speeds to/from network shares, as opposed to measuring network throughput or bandwidth , which is a completely different thing.
The NIC on a DNS-323 is capable of throughput of roughly 400 mbit/s (50MBytes/sec), which is well over anything you will see when actually transferring files, where the highest speeds I've seen are fractionally over 30MBytes/sec (sustained) on a read.

Hey fordem, i did a search for the link for NASTester and wasn't successful, do you know what it is, i would like to try this out and can't find the link.
Thanks in advance fordem

I believe the link for the NAS performance tester is
http://www.808.dk/?code-csharp-nas-performance
(Fordem, please correct me if this is not the utitlity
you were referring to)
-
thanks mig, i will try this out, hopefully it is the right one!!!
-
That's it mig - thanks much for stepping in.

Does the NASTester damage or destroy data on a NAS that already has data on it by any chance?
-
no.
-
No it does not.
The link should provide you with source code if you want to see how it works, but in a nutshell, it creates a temporary file on one disk, and then copies that across to the other disk, timing the copy and calculating the transfer rate, after which the files are deleted. The process is repeated, so to speak, in each direction so that you get both read & write speeds.
You have the option of selecting the file size (up to 2GB) and the number of iterations - if you select more than one iteration it will display the transfer rate for each run as well as an average.

I just tested NASTester .. and it reports that I have a
write (to NAS) speed of about 5.5MB/sec
read (from NAS) spped of about 18.5MB/sec
I have a GB NIC onboard (Asus P6T) connected to a Linksys WRT610N (Gigabit also)
and the DNS-323 is also connected to that router
all 3 devices are in the same room
Jumbo frames is set at 4000 in DNS-323
Jumbo frames on NIC is set to Auto
I have found nothing about jumbo frames on Router
IS there any thing I can do to improve those speeds (specialy the write)
-

Try disabling jumbo frames on both the DNS-323 and your PC.
-
I would start by disabling jumbo frame and re-testing, and then follow that with manually setting the frame size on the Asus (if possible), you'll need to test at different frame sizes to determine which works best for you.
Please also be aware that the computer you are reading from/writing to also has an impact on the transfer speeds - if you have another computer with gigabit try that also.

That sounds about right....
