Title: Post your Speed
Post by: vaz on September 08, 2011, 11:07:58 PM
I have a 323 and I'm looking to get a 325 in the future, but dlink has left a bad taste with their limitation on the 323 to about 120mbps on gigabit ethernet. So I'm interested to see what kind of transfer rate 325 owners are seeing with their gigabit transfers.

Where are viewing this information ·
You gigabit connection on all computers?

If your talking about the speed restriction, it's in fine print on the box. You would never notice it in the store.

I do not understand what you mean.

He's referring to the technical specifications printed (in very small writing) on the DNS-325 shipping box.

I looked very carefully at all sides of the DNS-325 box, which I still have since it was delivered only a few days ago, and I couldn't find any fine print mentioning this.

On the bottom side, it says:

1 Speed results may vary, depending on the benchmark utility, hard drive configuration, and the network environment used for testing.

"1" is found on the left side of the box:

High performance with Gigabit Ethernet connectivity 1

So the box doesn't promise gigabit per second speeds, and it doesn't say explicitly what speeds can be expected. Looks like they have hired a lawyer before printing anything on the box ;-)

the 323 has the 120mbps limit written on the box, I've never seen the 325 box. I just want to know what kind of transfer rates people are getting

It's quite likely the 325 has a similar limitation, then. It's just that the D-Link marketing guys thought it's better not to mention a specific figure. What utilities should be use to measure real transfer rates?

well if your on vista or 7 you can see the transfer rate by clicking on the more info arrow when you transfer a file. If you on a previous windows you can see transfer rate from the task manager by going over to network. It will display the transfer rate as a percentage. In this case 100% = 1gbps, so if you get 25% = 250mbps.

I find that information

I find that the actual speed attained is highly dependent upon the network infrastructure and what else is happening at the time.
In addition, speed measurements depend on what sort of data is being transferred; one large file will be much faster than lots of small ones and writes will be slower than reads.

Having said that (and using read speeds), I get about 2.5MB/s using a netbook connected wirelessly and 70MB/s using a desktop that is wired. The former is limited by the netbook itself and the latter is probably limited by the 325. On a *very* good day, laptops connected wirelessly are limited by the wireless bandwidth (400Mb/s) but mostly they are limited by the vagaries of RF propagation. I have not sought a PC that is connected to the same switch as the NAS for testing.

Transfers between wired desktop PCs are faster but for the most part the NAS is "fast enough". I would probably not notice the difference between 70MB/s and 100MB/s without a clock.

The 323 *might* have been slower but not noticeably.

Hope that helps.
Jack

70 is a huge improvement. If your using a magnetic disk hard drive, they usually top out between 60 and 90MB/s, which for communication purposes, 70MB/s is about 560mbps. The DNS 323 was limited to 120mbps = 15MB/s. The funny thing is that my Desktop routinely achieves about 6MB/s, which is annoying. My laptop will do 15 when wired.

Large file --- around 40MB/s
Smaller files --- 30-35MB/s

Tested with DIR-655 and DIR-855 with wired PC.
