USB transfer speed over network?

What kind of sustained transfer speed might I expect from the 323 when reading or writing files across a gigabit network to an external USB2 hard drive connected to it?

Thanks!

Re: USB transfer speed over network?

I'd guestimate at 170 mbps or thereabouts - could be less - and if you have jumbo frame, it could be a little more.

You do need to be aware however, that the DNS-323, out of the box, supports neither external USB drives, or jumbo frame - if you want them, you'll have to hack it, which is not difficult, the instructions are all here in this forum.

Re: USB transfer speed over network?

Thanks so much for the info fordem.

Wow 170mbps is fantastic, I am running a jumboframe gigabit network.  If I could get anywhere near 20MB/s I would be thrilled.

Last week I was between the DNS-323 and the ZyXEL NSA-220.  The hardware specs on the 220 were better but it's lacking the community the 323 has here.  I ended up going for the 220 and it's been very slow moving files over the USB connection. 

I'm seeing about 20MB/s on the internal and 1.2MB/s on the external USB

You may have helped me decide to return it and get the DNS-323

Does a hacked 323 also get about 170mbps from the internal drives too? (i.e. there is really no performance hit for using the USB connection?)

Re: USB transfer speed over network?

Rechecked my notes - seems my tests were done between a USB flash drive and the internal disks - 10 MB/s - the 170 mbps is what I get across the LAN to my internal disks, sorry for misleading you.

I would guess that the DNS-323 would give you better than 1.2 MB/s to an external drive, but, I don't have the required kernel modules loaded so I'm unable to run an actual test.

Again my apologies.

No worries, thanks for following up with that info.

If your hardware is capable of at least the 10MB/s internally it shouldn't be too much worse over the LAN I would presume.  Especially since the flash drive itself could have been the bottleneck.

If anyone else has numbers I would love to hear them too.

Thanks!

Re: USB transfer speed over network?

I just had to replace my unit and recopy the files to my NAS.  I saw the same 16-17 MB/sec when I copied from the NAS to the USB disk and back from the USB drive to the NAS.  The NAS has 2 750 GB WD drives in RAID 1 and the USB has a 750 GB Seagate.

Was that to/from a USB drive attached to the NAS itself?
